hi Claudio - we missed your question here.
No, the new logs aren't info-level, they're logWarns() - the new checks switch off canCreateEvents, so a warning seems appropriate.
Some of the older logs in the same function are indeed info-level - we'll check them out and let you know here if we change anything.

Hi, sorry for the delay in responding. At the moment everything looks perfect to me.
Do the new logs require the info level on the Calendar?

hi Claudio,
We've fixed these issues in 15.0 and will port them to 13.1 today.
There were a few categories of error:
1. hard-coded use of the default "startDate" and "endDate" field-names - crashes with non-standard start/endDateField
2. code-paths that assumed events had valid dates and made direct method calls, like event[calendar.startDateField].getTime() - crashes with missing event-dates
3. mouse-related date-detection issues for longEvents when firstDayOfWeek was non-zero - various visible misbehaviors of the ghost canvas
We've added some autotests to exercise firstDayOfWeek with longEvents, and also modified the internal autoDetectFieldNames() path, so that is sets canCreateEvents to false if start/end date fields aren't valid/can't be detected, and logs about it.
Please retest with tomorrow's builds, dated March 9 or later. Note that those builds will also address most of the matters raised by Blama in the related thread. We'll update there separately.

Hi, sorry for the confusion.
The issue is that the code causing the problem in my application was extremely basic, and the previous test cases seemed to reproduce it adequately.
However, I hadn’t actually realized what the trigger for the bug was; now I hope I’ve figured it out.
The problem seems to be caused by the startDateField having a different name than the default, which is why it didn’t happen with the tasks dataSource.
I’ve now tried changing the name in the dataSource in this way:
and the test case fails, in two different ways.Code:<DataSource isSampleDS="true" ID="tasks" serverType="sql" tableName="tasks" testFileName="/examples/shared/ds/test_data/tasks.data.xml" > <fields> <field name="taskId" type="sequence" hidden="true" primaryKey="true" /> <field name="name" type="text" title="Name" required="true" /> <field name="description" type="text" title="Description" /> <field name="foo" nativeName="startDate" type="datetime" title="Start Date" required="true" /> <field name="endDate" type="datetime" title="End Date" required="true" /> <field name="lane" type="text" title="Lane" required="true" /> <field name="eventWindowStyle" type="text" /> <field name="canEdit" type="boolean" hidden="true" /> </fields> </DataSource>
In the first case simply by running it:
Code:var _calStart = isc.DateUtil.getStartOf(new Date(2020, 6, 5), "W"); var _calEnd = _calStart.duplicate(); _calEnd.setDate(_calEnd.getDate() + 20); isc.Calendar.create({ ID: "testCal", startDate: _calStart, endDate: _calEnd, width: "100%", height: "100%", startDateField: "foo", currentViewName: "month", autoFetchData: true, dataSource: "tasks" })and in the second case (with autoFetchData: false) you need to click on a day:Code:18:44:56.131:XRP4:WARN:Log:TypeError: Cannot read properties of undefined (reading 'getTime') Stack from error.stack: _3.getDateColumn(<no args: exited>) on

Just to follow up here Claudio - your proposed addition of a field didn't add any values into that field in the data. It was a nonsense addition, without corresponding values on records.
If you find bugs, It will really be best to just provide a calendar with the data you expect it to have, and explain why it doesn't have it. Pointing a calendar at supplyItem, which has nothing at all to do with calendar events, is really not the way to go.Leave a comment:

hi Claudio - when you say "it doesn't seem to do it", what do you mean by that?
It kind of seems like you're trying to force a situation that you already have in your code. You're trying to forcibly inject a different field into a built-in test DS right?
Can you please just show us the actual code that fails?

Thanks for the suggestion about the tasks dataSource. From a quick test, it doesn’t seem to do it.
However, this seems odd to me: the test case in post #4 didn’t appear to have anything illegal - there are two datetime fields in the dataSource:
which are used for the Calendar:Code:<field name="nextShipment" type="datetime" title="Next Shipment"/> <field name="endDate" type="datetime" customSelectExpression="TIMESTAMPADD(SQL_TSI_HOUR, 1, nextShipment)"/>
am I missing something obvious?Code:startDateField:"nextShipment", endDateField:"endDate"

Could you perhaps post a sample that does not rely on an unrelated table? SupplyItem has no relation at all to calendars. Use the task datasource if you want to report issues with calendars, or provide a proper calendar-event DS.Leave a comment:

Hi, please note that in post #4 I've posted an updated test case, with an endDate field in both dataSource and Calendar.Originally posted by Isomorphic View PostLeave a comment:

Yes, apologies, the fixes didn't hit 13.1 builds in time for today's builds.
But note that your test-case is just wrong - it wouldn't be expected to work in any previous version or any current one. There is only one date-field in the DS.

hi Claudio,
The problems you mentioned have the same source - the test-case uses an unrelated DataSource, supplyItem, which only has one date-field, and events need start and end dates.
If you instead start from the id=databoundCalendar/Timeline samples, which use a valid calendar-event DS with start and end date fields, you won't see this crash or the bad ghost positioning.
We'll address the unsightly crash for today's builds, and perhaps set canCreateEvents to false if there aren't valid date-fields on the DS - but the test is basically invalid as-is.
Some other fixes will also hit today's builds, from the other on-going thread about this feature.Last edited by Isomorphic; 6 Mar 2026, 21:48.Leave a comment:

Hi Isomorphic I found the catch. To reproduce the error, it’s necessary to use a locale like the Italian one, where the week starts on Monday.Leave a comment:

Month view: clicking empty day shows longEventsLayout and triggers fetch
SmartClient Version: v13.1p_2026-03-05/AllModules Development Only (built 2026-03-05)
Hi, I found an issue in a Calendar in my application that I’m not able to reproduce in the showcase.
Basically, when clicking on a day with no events in the month view, I get the following stack trace:
While trying to reproduce the issue in the showcase, however, I noticed other problems that may or may not be related. With the following test case:Code:ISC_Core.js?isc_version=13.1-p20260305.js:68250 Uncaught TypeError: Cannot read properties of undefined (reading 'getTime') at cons.getDateColumn (ISC_Calendar.js?isc_version=13.1-p20260305.js:1006:53) at cons.getDateLeft (ISC_Calendar.js?isc_version=13.1-p20260305.js:1015:31) at cons.updateGhostCanvas (ISC_Calendar.js?isc_version=13.1-p20260305.js:287:38) at cons.showGhostCanvas (ISC_Calendar.js?isc_version=13.1-p20260305.js:344:18) at Array.callMethod (ISC_Core.js?isc_version=13.1-p20260305.js:15309:66) at cons.showGhostCanvas (ISC_Calendar.js?isc_version=13.1-p20260305.js:1062:36) at cons.startGhostDragCreate (ISC_Calendar.js?isc_version=13.1-p20260305.js:1167:14) at cons.cellMouseDown (ISC_Calendar.js?isc_version=13.1-p20260305.js:7894:14) at cons.eval [as cellMouseDown] (eval at isc__makeFunction (ISC_Core.js?isc_version=13.1-p20260305.js:2663:21), <anonymous>:4:127) at cons._cellMouseDown (ISC_Grids.js?isc_version=13.1-p20260305.js:13574:37) at cons.mouseDown (ISC_Grids.js?isc_version=13.1-p20260305.js:13552:21) at cons.handleMouseDown (ISC_Core.js?isc_version=13.1-p20260305.js:108122:37) at cons.bubbleEvent (ISC_Core.js?isc_version=13.1-p20260305.js:66415:44) at cons.doHandleMouseDown [as _$observed_doHandleMouseDown] (ISC_Core.js?isc_version=13.1-p20260305.js:62316:28) at cons.observation [as doHandleMouseDown] (ISC_Core.js?isc_version=13.1-p20260305.js:8659:46) at cons.handleMouseDown (ISC_Core.js?isc_version=13.1-p20260305.js:62144:26) at cons.dispatch (ISC_Core.js?isc_version=13.1-p20260305.js:68246:30) at HTMLDocument.eval (eval at isc__makeFunction (ISC_Core.js?isc_version=13.1-p20260305.js:2663:21), <anonymous>:3:127) getDateColumn @ ISC_Calendar.js?isc_version=13.1-p20260305.js:1006 getDateLeft @ ISC_Calendar.js?isc_version=13.1-p20260305.js:1015 updateGhostCanvas @ ISC_Calendar.js?isc_version=13.1-p20260305.js:287 showGhostCanvas @ ISC_Calendar.js?isc_version=13.1-p20260305.js:344 callMethod @ ISC_Core.js?isc_version=13.1-p20260305.js:15309 showGhostCanvas @ ISC_Calendar.js?isc_version=13.1-p20260305.js:1062 startGhostDragCreate @ ISC_Calendar.js?isc_version=13.1-p20260305.js:1167 cellMouseDown @ ISC_Calendar.js?isc_version=13.1-p20260305.js:7894 eval @ VM73634:4 _cellMouseDown @ ISC_Grids.js?isc_version=13.1-p20260305.js:13574 mouseDown @ ISC_Grids.js?isc_version=13.1-p20260305.js:13552 handleMouseDown @ ISC_Core.js?isc_version=13.1-p20260305.js:108122 bubbleEvent @ ISC_Core.js?isc_version=13.1-p20260305.js:66415 doHandleMouseDown @ ISC_Core.js?isc_version=13.1-p20260305.js:62316 observation @ ISC_Core.js?isc_version=13.1-p20260305.js:8659 handleMouseDown @ ISC_Core.js?isc_version=13.1-p20260305.js:62144 dispatch @ ISC_Core.js?isc_version=13.1-p20260305.js:68246 eval @ VM73574:3Understand this error ISC_Core.js?isc_version=13.1-p20260305.js:68250 Uncaught TypeError: Cannot read properties of null (reading 'getDay') at cons._getEventDialogTitle (ISC_Calendar.js?isc_version=13.1-p20260305.js:20032:29) at cons.setDate (ISC_Calendar.js?isc_version=13.1-p20260305.js:18484:31) at cons.setEvent (ISC_Calendar.js?isc_version=13.1-p20260305.js:18520:18) at cons._showEventDialog (ISC_Calendar.js?isc_version=13.1-p20260305.js:19846:12) at cons.showEventDialog (ISC_Calendar.js?isc_version=13.1-p20260305.js:19785:10) at cons.finishGhostDragCreate (ISC_Calendar.js?isc_version=13.1-p20260305.js:1251:13) at cons.cellMouseUp (ISC_Calendar.js?isc_version=13.1-p20260305.js:7918:18) at cons.eval [as cellMouseUp] (eval at isc__makeFunction (ISC_Core.js?isc_version=13.1-p20260305.js:2663:21), <anonymous>:4:127) at cons.mouseUp (ISC_Grids.js?isc_version=13.1-p20260305.js:13688:35) at cons.invokeSuper (ISC_Core.js?isc_version=13.1-p20260305.js:7474:44) at cons.Super (ISC_Core.js?isc_version=13.1-p20260305.js:7291:21) at cons.mouseUp (ISC_Grids.js?isc_version=13.1-p20260305.js:17834:21) at cons.handleMouseUp (ISC_Core.js?isc_version=13.1-p20260305.js:108134:35) at cons.bubbleEvent (ISC_Core.js?isc_version=13.1-p20260305.js:66415:44) at cons._handleMouseUp (ISC_Core.js?isc_version=13.1-p20260305.js:63030:44) at cons.handleMouseUp (ISC_Core.js?isc_version=13.1-p20260305.js:62934:26) at cons.dispatch (ISC_Core.js?isc_version=13.1-p20260305.js:68246:30) at HTMLDocument.eval (eval at isc__makeFunction (ISC_Core.js?isc_version=13.1-p20260305.js:2663:21), <anonymous>:3:127)
in the month view, when clicking on a weekday, in addition to the Dialog opening to create the event, a longEventsLayout is displayed that goes from Sunday to the clicked day.Code:isc.Calendar.create({ ID:"aCalendar", width: "100%", height: "100%", autoFetchData: false, dataSource: "supplyItem", currentViewName:"month", startDateField:"nextShipment" , implicitCriteria:{_constructor:"AdvancedCriteria", operator:"and",criteria:[{fieldName:"nextShipment", operator:"notNull"}]} });
Also, a fetch is triggered on click (note that autoFetchData is false).
