[Trinidad] Problems with tr:table SelectionEvent

[Rafa Pérez]

Hi all,

I need to distinguish between a SelectionEvent delivered when a checkbox is ckecked or when 'Select all' or 'Select None' is clicked. I have been looking into the code and the examples but have not found anything yet (I am surprised that nobody ever needed this feature...).

I have been looking at the internals (javascript) and it seems that there is a hidden input in the generated HTML that has a value "all" or "none" for this purpose. However, when the form is submited in the PPR event, all its hidden fields are cleared and thus, this hidden field never sends its value to the server. Am I wrong? Is this working as it is supposed? Is there any way I can know if the event was generated by clicking the links or the checkbox?

TIA,

-- Rafa

Did you have a look at the SelectionEvent? It (or exactly: its super class) has methods "getAddedSet()" and "getRemovedSet()". Maybe you can check whether the size of the set is > 1 and can infer by that, whether only one item was checked/unchecked or 'select one' or 'select none' was clicked.

Regards, Marco

Yes, I thought about this, but if there is only one element in the table (only one result for a search or only one element in the current page of the navigation range), you can not know what happened... Any hints?

Thanks,
