Subject [Trinidad] PPR between two tr:tables not updating selection
Date Wed, 26 Sep 2007 08:19:50 GMT
Hello list,

I have a page with two tr:tables in. The first contains checkboxes and
the second radio buttons (i.e. rowSelection="single" and "multiple"
respectively). Since the first represents queues, and the second users
assigned to those queues, changing selected queue should change the
selected users, that is when a queue is selected, the user table should
show the appropriate users selected in it.

I can achieve this the first time a queue is selected, by calling a
presetSelections method when the bound table is set in the bean. I can
not get it to update on selection events, however.

I'm using PPR and I know that setting the partialTrigger for the second
table to the first table isn't enough -- the second table's selections
need to be reset. I therefore have a selection listener on the first
table which calls a resetTableSelections method which then calls
table.resetStampState(), where table is the property bound to the second
table.

The stamp state is duly reset, but the selections on the table do not
change in the browser. The previous selections are being restored, not
recalculated. This morning I've tried experimenting with a phase
listener to get in there and call the preset method. I thought a likely
place would be after the apply request values phase, as the events would
have been processed, and any changes in the first table registered.
However this caused null pointer exceptions in the render response phase
-- the collection backing the first table. None of the other phases I
tried gave a noticeable effect.

I enclose the stack trace. Was using a phase listener an appropriate
approach to this problem?  Is there a better way?

Cheers,
Edd
