CForms multivalue field breaks if used within union widget with AJAX
enabled??
Hi,
I'm having trouble using a multivalue field within a union - at least
with mozilla based browsers and AJAX enabled I'm getting JavaScript
errors and the multivalue field stops working.
Attached is a very simple example that reproduces the problem. The tar
is intended to be extracted into a default cocoon installation in the
folder where the main cocoon sitemap resides and is then accessible via
http://localhost:xxxx/..../uniontest/uniontest. I'm using Cocoon 2.1.8.
The attached example lets you swich cases via a drop down box - very
similar to Datasource chooser sample in cocoon. Case 1 has a multivalue
field in it, case 2 has a simple field. Upon first loading, the default
case (the multivalue field) is displayed. Everything's fine so far. You
can now swich to case 2, so the simple field gets displayed. However,
from now on it is not possible to swich back to the multivalue field -
at least not with Mozilla or Firefox, IE works fine...
In the Javascript console I can see the following error when trying to
switch back:
Error: this.entry has no properties
Source File:
http://localhost:8080/cocoon2.1.8/policyeditnew/resources/forms/js/forms-lib.js
Line: 234
This is located in the FormsMultiValueEditor JavaScript class that gets
instanciated as part of the multivalue field on the bowser side. Also
this is perfectly working upon first loading the page, it seems that the
partial AJAX updates that Mozilla / Firefox retrieves are not
immediatelly accessible via getElementById. Thus, the first lookup in
FormsMultiValueEditor() fails and causes Mozilla / Firefox cancelling
the new FormsMultiValueEditor() call together with the complete div
replacement and things stop working.
(By the way: The same behaviour occurs when using a multivalue field
within a repeater that has move actions associated with the repeater
rows. As soon as a move has been triggered, the multivalue field stops
working.)
Is this a known problem or is it possible to work around this? I've
dived into this somewhat, but my knowledge of JavaScript is still very
limited. Any help is greatly appreciated.
Thanks!
Ralph

Antonio,
you're right! I've tried it - this behaviour has nothing to do with
AJAX. The values are lost in 2.1.9-dev with AJAX enabled as well as with
AJAX disabled.
Thanks again for your help.
Wish you a nice weekend.
Ralph

Hi Ralph, many thanks for your feedaback!
I used the online cocoon demo site for 2.1.9-dev [1] and I can confirm
this bug.
Step to reproduce:
1- Selected type 'SQL' and added some text in the 3 fields.
2- Selected type 'file'.
3- Select typw 'SQL' again
Result: All the original info in the 3 fields is lost.
Expected: the form must remember the values of the 3 fields for type
'SQL' and show then again after step '3'.
Is this correct?
Question: Have you tried to turn off ajax to see if this is an ajax
issue at all?
Best Regards,
Antonio Gallardo.

It did. At least with the Cocoon 2.1.8 release.

Yes, there is a sample. The datasource chooser in the cforms samples
section shows the problem. When switching union cases, the values are
being remembered when using a cocoon 2.1.8. Using 2.1.9-dev values
entered (or values initially loaded via binding) are lost when switching.

Did it work before?

I don't know. But of course it needs to be addresed. Is a sample is
cocoon code that shows this problem? If not, can you provide a simple
sample?

Thanks! The 2.1.9-dev fixes the problem - the javascript error is gone
and switching cases now works. However, there's a new problem. If I
switch back and forth between union cases the values entered are not
being remembered any more. Is this already being addressed - if not,
maybe someone can point me into the right direction so I can have a look
into this myself.
Best regards
Ralph

In cocoon 2.1.9-dev there are already fixed some ajax issues.
