Hi,
I have a code peace that recalculates a grid:

Code:
	
 public void onRowSelect() {
 			selectedQuery = this;
 			// listOfInteractiveComponents.deselectCurrentSelection();
 			AnalyticQuery analyticQuery = selectedQuery.getAnalyticQuery();
 			if (analyticQuery != null) {
 				ArrayList<String> dependencies = analyticQuery.getDependencyList();
 				if (dependencies != null) {
 					ArrayList<ComponentItem> list = (ArrayList<ComponentItem>) listOfInteractiveComponents.getItems();
 					for (ComponentItem component : list) {
 						if (dependencies.contains(component.getComponentId())) {
 							// component.setSelected(true);
 							listOfInteractiveComponents.selectItem(component, false);
 						} else {
 							// component.setSelected(false);
 							listOfInteractiveComponents.deselectItemWCB(component, false);
 						}
 					}
 				}
 			}
 		}

I use
Code:
 listOfInteractiveComponents.selectItem(component, false);
 listOfInteractiveComponents.deselectItemWCB(component, false);

as I don't want to receive any callbacks to onRowSelect/onRowDeselect of the grid's item.

As shown here I cannot stop it:

Shall I use component.setSelected(false); which is not recommend by the API?

Hi,

NEVER call setSelected() on Item level!!! The JavaDoc tries to "forbid" this to everyone... ;-)

BUT: call selectItem/deselectItem - both methods provide a parameter variant by which you can decide if to execute the normal "binding processing" (onRowSelect/Deselect). Please check JavaDoc of FIXGRIDBinding.

Hi Björn,

I did so. I used false as actual parameter. But the items were called back!

...oh, yes you're rigfht: in the deselect case the boolean parameter is something different (I shoud have checked the javadoc on my own...)

We can add such a method...
