[Trinidad] Problems with tr:table SelectionEvent

[Rafa Pérez <ra...@gmail.com>]

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

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,

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.
