Problems to reRender a columnGroup (there's no id)

[hwoarang]

Hi there!

After some debugging (using Firebug) I noticed that my r:columnGroup don't have an Id, even when I explicity type one. So I can't use reRender='myColumnGroupId'.

I tried javascript too, but without Id I don't know how to access my component.

I can see the auto generated id for r:column, but not for r:columnGroup. Someone has an idea why this happens?

What I'm trying: hide/show a columnGroup from h:selectOneMenu onchange event.

my code:

<r:columnGroup>
 <r:column>
 <h:selectOneMenu value="#{myBean.propertyName}">
 ...
 <a4j:support event="onchange" reRender="columnGroupId" />
 </h:selectOneMenu>
 </r:column>
</r:columnGroup>

<r:columnGroup id="columnGroupId" rendered="#{myBean.propertyName} == 'A'">
 ...
</r:columnGroup>

Hi,

I've created an issue for that: https://jira.jboss.org/jira/browse/RF-5081

and by the way even if we add the id you requested - your code is wrong. It's not allowed to reRender partially rendered components. Only the parents of such components.

@nbelaevski: thank you.
I'll follow the issue.

@ilya:
sorry, I didn't understood "It's not allowed to reRender partially rendered components.".
I changed my code to reRender my r:column's and works (but I need to put rendered options more than I think it should).

thank you all

sorry I've used wrong word :) should be "not allowed to reRender conditionally rendered components."
