[SOLVED, BUT] Re: REPOST: Cocoon Forms - Javascript errors

[Derek Hohls <DH...@csir.co.za>]

Found the cause of the error - in my "remove value" repeater
I had not correctly specified the selector widget that determines
which row/s has been selected for deletion ie.  I had:

<fd:repeater-action id="removedata_value" action-command="delete-rows"

  repeater="data_value" select="select">

instead of:

<fd:repeater-action id="removedata_value" action-command="delete-rows"

  repeater="data_value" select="data_value_select">

I do think that a better error message could have been generated;
if the sytem had complained it could not find a widget with
name "select", then at least I would have had somewhere to
start looking...

Well, the Form.js file is the standard one supplied with Cocoon;
if that was faulty, I would assume every cforms app would fail
in some way....  perhaps my topic header should be titled
'Errors deleting repeated rows in nested CForm'.

hi derek

have you ever looked into the file Form.js (line 127)? perhaps you get
a 
hint what's causing this nullpointer-exception...
