Hello, I'm writing a custom Composite widget which contains a CellTable. This CellTable must always have an item selected. (I wrote an implementation of DefaultSelectionModel to achieve that). And every time the selection changes, a specific SelectionEventHandler must be invoked to perform some modifications in the widget - modifications which depend on the selected element.
This CellTable must be populated with an AsynDataProvider which is given by "user code", so I can't really change it to adapt to my widget "internals". How can I make sure that the selection model will fire a SelectionChangeEvent every time the range changes and the new data is asynchronously set by the provider? The main problem here is that my SelectionEventHandler must be executed after the asynchronous request completes, because it depends on the data loaded from the server. If I simply add another RangeChangeHandler to the CellTable, even if I add it after the one added by the AsyncDataProvider, that is not enough because it is likely to execute before the call to the server returns. I saw there's an addValueChangeHandler on AbstractHasData, which could help me I guess, but unfortunately it is package protected, and the javadoc gives the impression it only works for CellBrowser, not CellTable. Anyone has any idea that could help me? If there was a way to add a handler that would react after the AsyncDataProvider calls updateRowData that would be great...
