[ http://issues.apache.org/jira/browse/MYFACES-603?page=all ]
Martin Marinschek updated MYFACES-603:
--------------------------------------
Status: Resolved (was: Patch Available)
Fix Version/s: 1.1.2
Resolution: Fixed
Assignee: Martin Marinschek
Any duplicate id exceptions due to dynamic addition of components to the tree
(or also due to different points in time when getClientId is accessed) should
have been fixed by me last december.
If this still occurs in 1.1.4, we need to reopen, but I doubt it.
regards,
Martin

> When reloading a page, I get the exception below.
> I search the mailing list and someone suggested to assign a id by hand
> to every component - which is much work and would clumber the jsf pages.
> I manualy added an id to the component with the duplicate id and
> redeployed the app - now I get the exception from another component. So
> what changed from 1.0.9m9 to 1.1.0 related to this problem?
> Another strange thing is that I get the following warning:
> 2005-09-20 15:06:39,481 INFO [/XXX]: WARNING: Component _id12 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!
> Everything went away after I rearragned the components like this:
> Original:
> <f:view>
> .. jscookmenu
> ... dataTable with command links
> <h:form>
> ... more dataTable with more command links
> </h:form>
> </f:view>
> Now without problems:
> <f:view>
> ... jscookmenu
> <h:form>
> ... dataTable with command links
> ... more dataTable with more command links
> </h:form>
> /f:view>
