Fecth&UpdateData on ListGrid not executed

[AHagerer]

Hello,

I am using SmartClient/SmartGWT Framework v9.1p_2014-04-18/Pro Deployment.

I created an array of two listgrids which are shown in tabs of a tabset and which are associated with the same datasource.
If fetch is called on listgrid[0] it is not executed. The developer console does not show an RPC-call.
If I change list[0].fetch to list[0].getDataSource.fetch the fetch is executed.
Same holds for updateData

Where's my mistake?

Thank you
Andreas

Hi Andreas,

you'll need to show some code.
What comes in my mind:
- Are the lg different Java objects?
- Did you reuse ListGridFields in the lgs?

Best regards,

Hi,

Here are some code fragments:
1. ListGrid creation

examList = new ListGrid[2];
examList[0] = createExamList ();
examList[1] = createExamList ();
...
private ListGrid createExamList () {
	final ListGrid examList = new ListGrid () {
		protected String getCellCSSText (final ListGridRecord record, final int rowNum, final int colNum) {
                ...
		}
	};

	examList.setSelectionType (SelectionStyle.MULTIPLE);
	examList.setCanEdit (true);
	examList.setEditByCell (false);
	examList.setAutoSaveEdits (true);
	examList.setAutoFetchData (false);
	examList.setDataFetchMode (FetchMode.BASIC);
	examList.setFilterLocalData (true);
...
	return examList;
}

2. Assigning datasource to lg

public void setExamDS (final DataSource examDS, final Tree bldgTree) {
	// List of field names to be shown
	final List<String> lgFields = new ArrayList<String> ();
	lgFields.add ("prfgGruppe");
	lgFields.add ("stg");
	lgFields.add ("titel");
	lgFields.add ("prueferNamen");

	ListGridField f;
	final List<ListGridField> lfld = new ArrayList<ListGridField> ();
	for (final ListGrid exlst : examList) {
		exlst.setDataSource (examDS);
		lfld.clear ();
		// prepare list of fields not to be shown
		for (final ListGridField lf : exlst.getFields ()) {
			lf.setCanFilter (false);
			if (lgFields.contains (lf.getName ())) {
				lf.setCanEdit (false);
			} else {
				lfld.add (lf);
			}
		}
		final ListGridField[] o = new ListGridField[lfld.size ()];
		exlst.hideFields (lfld.toArray (o));

		// configure fields
		f = exlst.getField ("prfgArt");
		f.setAlign (Alignment.CENTER);
		f.setCanFilter (true);
		f = exlst.getField ("prfgStatus");
		f.setAlign (Alignment.CENTER);
...

3. fetch

	final Integer id = Integer.valueOf ((String)planorgSelector.getValue ());
	final Criteria crit = new Criteria ();
	crit.addCriteria ("semid", AbstractWindowPresenter.getCurrentSemId ());
	crit.addCriteria ("orgid", id);
	crit.addCriteria ("inprfg", true);
	examList[0].fetchData (crit, new DSCallback () {
		@Override
		public void execute (final DSResponse response, final Object data, final DSRequest dsRequest) {
			examList[0].setData (response.getData ());
			examList[0].ungroup ();
			examList[0].unsort ();
		}
	});

Since in other cases the same steps (creation, assigning, configuring, fetch) work I think that I forget something or I did something in wrong order.

Bye

Hello,

I reduced the code and found out the reason.

I configured the ListGrid with 'setFilterLocalData (true)' in combination with 'setAllowFilterExpressions (true)' since I don't want to evaluate expressions like '..., OperatorId.GREATER_THAN, 10' on the server.
But if the configuration 'setFilterLocalData (true)' is set first, a 'listgrid.fetchData()' is not performed.
However, 'listgrid.getDatasource().fetchData()' works and the result passed to the listgrid by 'setData()' is filtered locally.

Thank you
Andreas

Hello,

I have still difficulties with this setFilterLocalData-ListGrid.

The editor of a cell is a PickTreeItem.
In the changedHandler of the corresponding field the updateData-operation on the datasource is performed:

final Integer prfgpId = (examList[0].getSelectedRecord ()).getAttributeAsInt ("prfgGruppenId");
final Record[] prfgrp =
	examList[0].findAll (new AdvancedCriteria ("prfgGruppenId", OperatorId.EQUALS, prfgpId));
for (final Record r : prfgrp) {
	r.setAttribute ("roomId", event.getValue ().toString ());			
	examList[0].getDataSource ().updateData (r, new DSCallback() {
		public void execute (final DSResponse dsResponse, final Object data, final DSRequest dsRequest) {
			examList[0].getDataSource ().updateCaches (dsResponse);
		}
	});
}

After these activities the cell shows the value of the ValueField instead of the value of the DisplayField.

Any suggestions.
Thank you
Andreas
