yep i think to ;) i will make one tonight or tomorrow

I have been having trouble with interaction between ListGrids and clientOnly:true datasources when it comes to removing records.

After much poking around, the simplest example of failure I could come up with is the following:

Open the feature explorer:

/isomorphic/system/reference/SmartClient_Explorer.html#localDataSource

OR browse to the 'Data Binding' > 'Lists' > 'Local DataSource' example.

Go to the JS tab and add the line canRemoveRecords:true so that it looks as follows:

isc.ListGrid.create({
    ID: "countryList",
    width:500, height:224, alternateRecordStyles:true, showAllRecords:true,
    dataSource: countryDS,
    autoFetchData: true,
    canRemoveRecords:true
})

Click 'Try It'...

Although the red crosses appear by each row, if I click one, the record does not disappear.

I would expect the behaviour of a clientOnly datasource to be that when I click remove, the record is removed from the testData set.

Programatically calling removeSelectedData or removeData(primary_key) on the ListGrid also do not result in the records disappearing.

Behaves this way on SmartClient 7.0rc2 (& nightly SmartClient_SC_SNAPSHOT-2010-07-17) on Win:IE8 IE7 OSX:FF Chrome Safari

That DataSource has no primaryKey declared. Primary keys are required for data changing operations to complete (for any DataSource type).

Many thanks, this solved my problem. It appears to have solved my programatically calling the remove functions, too.

If anyone is interested, I found another way to remove data from list grid:

RecordList list = listGrid.getRecordList();
for (int i = list.getLength()-1; i >=0 ; i--) 
	listGrid.removeData(list.get(i));

[rtsan]

yourListGrid.setData(new ListGridRecord[0]);

should empty the list.

Hi,

Take a look at this post -> http://uptick.com.au/content/crud-gwt-gwtp-smartgwt-and-jpa and the ListGrids used in the sample code.

Cheers

You're the only one experiencing this "bug" while others are reporting that it works.

Don't file a ticket. Try producing a standalone test case instead.

Actually I also met the exactly same issue, maybe some more other people met this same issue but just did not report here... very horrible bug...

I add datasource to a listgrid and use the ds just for client-only. prior to smartgwt 2.2 releases,we use the following two code lines to clear the data in the list grid and it worked fine:
listgrid.invalidateCache();
listgrid.getDataSource().setTestData(null);

now we use Smartgwt2.5(we also tried the previous ones after 2.2)and we cannot clear the listgrid data.

Info to clear ListGrid

I beliew in self coding,

rlPriceGrid.setData(new ListGridRecord[] {});

How many agree with me....:)
