I'm hitting a problem with auto-refreshing= of tables using Trinidad 1.2.1, facelets and JSF 1.2 (Sun RI). I've conden= sed the scenario down to a small test case shown below. The summary is:
=
- I have a page which displays a table containing a collection of objec= ts
- Each row of the table contains two command links - one to edit the= row and another to delete the row
- Both links pop-up a dialog with det= ails of the row. Hitting the "save" button on the dialog will either save t= he edit changes (if invoked from the edit link) or delete the row (if invok= ed from the delete link).
- The table has a partialTriggers attribute wh= ich attempts to refresh the table contents whenever a row is edited or dele= ted (i.e. partialTriggers contains the ids of the edit and delete links)- Everything appears to work fine apart from deletion of the last row in t= he table whereby the table does not automatically refresh.

Is this = a bug or am I doing something silly? Is there a better way to achieve what = I'm trying to do?

thanks in advance for any help.
