a4j:region and facelets UIText and UILiteralText

[andrew.rw.robinson]

Is there any way to stop the following when using facelets and a4j:regions?

13:15:57,249 INFO [[/App]] WARNING: Component pageForm:_id1441 just got an automatic id, because there was no id assigned yet. If this component was created dynamically (i.e. not by a JSP tag) you should assign it an explicit static id or assign it the id you get from the createUniqueId from the current UIViewRoot component right after creation!

It is coming from the inline facelets text that is transient (UIText and UILiteralText).

Piece of the code:

<a4j:region>
 <t:selectOneRadio
 value="#{bean.value}"
 layout="pageDirection"
 styleClass="radio">
 <a4j:support
 event="onclick"
 reRender="treeZone"
 ajaxSingle="true" />
 ...

I added the region because otherwise other controls that depend on submitted values break while using ajaxSingle="true" on the a4j:support. In my case, I was having checkboxes that were checked go back to unchecked (since there was no submitted value). I want to render items outside the region, so renderRegionOnly and selfRendered don't seem to be applicable.

The code works just fine and there are no bugs, but the messages in the logs are annoying to say the least (our QA would probably report them as bugs).

I would think there would be other posts/emails on this but I was unable to find it so sorry if this has been previously answered

No reply = no solution to this problem?

Hi,
Sorry but I'm unable to reproduce your warning message. Could you provide an example for me directly? Thanks.

Sorry for the delays.

probably, the attachment to jira issue is better than direct mail.

I think I figured it out. Since you said you couldn't reproduce it I decided to try facelets 1.1.11 instead of 1.0.14. It doesn't seem to be happening anymore with 1.1.11.

Thanks

Okay, I just got it again. This time is when I re-render a component that contains a ui:include element. If I change the value of the ui:include from a region that doesn't contain the include, then I seem to be getting it.

<a4j:outputPanel id="panel">
 <ui:include src="#{bean.value ? 'a.xhtml' : 'b.xhtml'}" />
</a4j:outputPanel>
<a4j:region>
 <h:selectBooleanCheckbox value="#{bean.value}">
 <a4j:support ajaxSingle="true"
 event="onclick" reRender="panel" />
 </h:selectBooeanCheckBox>
</a4j:region>

I don't have a simple example other than this yet to send, but hopefully you can know what is going on from this.

Please use Sergey's suggestion about jira :) On me side (ajax4jsf-1.1.1-20070408.230846-5, richfaces-3.0.1-20070409.000312-4, JSF 1.2.04, Facelets 1.1.12) your code renders the include fine.

[andrew.rw.robinson]

I can't reproduce it with a simple use case yet. Something in our application must be helping to cause it. I'll get back to this post if I can reproduce it with a simple example and post it to a JIRA issue for research.

Okay, found it. Originally, when I was using facelets 1.0.14 I seemed to be getting some of these messages from UIText and UILiteralText. It looks like facelets 1.1.11 got rid of that. The messages I still kept getting were not related to the UIText and UILiteralText. The problem is a bug in "org.apache.myfaces.custom.datascroller.HtmlDataScrollerRenderer" in MyFaces/Tomahawk 1.1.5.

In that code, they create an HtmlOutputText object using application.createComponent(String), but never assign an ID to that component. As a result, all the command links will have a child component with no ID. One of my includes had a table with a paginator, and hence why I was only getting the message with one include.

I also found a couple of our custom component renderers that had the same problem (transient created components with no ID assigned to them).

Sorry for the rabbit trail on this forum. Not sure why I wasn't seeing this issue until I started using the region tag (maybe I just never noticed it before?).

Thanks for the help and any work put in.
