  • 11.1p Exception in Showcase and request flood in application on ListGridField hover

    Hi Isomorphic,

    please see this showcase sample (v11.1p_2018-01-09), which causes many errors like this in the Developer Console on hover for me.
    Code:
    15:46:11.806:TMR9:WARN:Label:isc_Label_2:Attempt to access destroyed widget in the DOM - destroy() called at invalid time (eg: mid-draw) or invalid method called on destroy()d widget. Stack Trace:

    In my code I'm using this at field level with ListGridField.setShowHover(true) + ListGridField.setShowHoverComponents(true) and then
    Code:
        @Override
        protected Canvas getCellHoverComponent(Record record, Integer rowNum, Integer colNum) {
            if ("myfield".equals(getFieldName(colNum))) { ....
    For me locally, it does not result in exceptions, but in many calls to the DB in the ListGrid I'm returning from getCellHoverComponent(), basically on every mouse-move.
    IMHO as long as the mouse is over the field, the hover should not be recreated and moving the mouse over the field should not change anything.

    We did some testing and were not able to reproduce and see the reported warning messages. We need more information on how to reproduce the issue, or post a standalone test case so that we can test it.

      Hi Isomorphic,

      using current online showcase (v11.1p_2018-01-11) I don't see the log issue either?!
      Is it possible that it was fixed in the meantime or that it was caused by some intermittent issue?

      I'll create a testcase for my "many calls to the DB"-issue I can see in my application soon.

      Best regards

        Hi Isomorphic,

        I created the testcase I mentioned in #3 here.
