startEditingNew not working

[tholmes66]

I've got a working ListGrid with a GWT-RPC datasource. I can fetch existing data and display it in the ListGrid without any problems. I am using the sample code from the showcase, for databound dependent-selects.

The datasource does have a pkField with the properties set as follows:
pkField = new DataSourceIntegerField("Id", null);
pkField.setPrimaryKey(true);
pkField.setCanEdit(false);
pkField.setRequired(true);
pkField.setRootValue(0);

The code to add a new row is as follows:

addDataButton.addClickHandler(new ClickHandler() {
	public void onClick(ClickEvent event) {
		field1.setCanEdit(true);
		field2.setCanEdit(true);
		myGrid.startEditingNew();
	}
});

I get the dependent-selects opened just fine.
There are 4 columns, the first column (pkField), and the last column are not editable.

So ... after I select an item from the first-selection, it does not go to the next drop-down combo-box.

field1.addChangedHandler(new com.smartgwt.client.widgets.grid.events.ChangedHandler() {
	public void onChanged(com.smartgwt.client.widgets.grid.events.ChangedEvent event) {
                myGrid.clearEditValue(event.getRowNum(),"dataName");
	}
});

Instead, the added new record disappears.

If I click on an existing record, this doesn't happen.

Any help would be very much appreciated! Thanks!

This was occuring for me as well. What I discovered is that if the cell you are trying to clear is null, (ie. as in a new record) then the new row is removed by SmartGwt when you call 'clearEditValue'.

Adding a check in the onChanged handler to make sure the value is not null solves the problem.

field1.addChangedHandler(new com.smartgwt.client.widgets.grid.events.ChangedHandler()
{
public void onChanged(com.smartgwt.client.widgets.grid.events.ChangedEvent event)
{
Object val = listGrid.getEditedCell( event.getRowNum(), "dataName" );
if ( val != null )
{
myGrid.clearEditValue(event.getRowNum(),"dataName");
}
});
