     [ http://issues.apache.org/jira/browse/MYFACES-603?page=all ]

Kenji Nagahashi updated MYFACES-603:
------------------------------------

    Status: Patch Available  (was: Open)

> duplicate id exception
> ----------------------
>
>          Key: MYFACES-603
>          URL: http://issues.apache.org/jira/browse/MYFACES-603
>      Project: MyFaces Core
>         Type: Bug

>   Components: General
>     Versions: 1.1.0
>  Environment: Tomcat 5.5.9, JDK 1.4.2, Windows NT
>     Reporter: Boris Klug
>     Priority: Minor

>
> 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>
> === Thrown exception ====
> 2005-09-20 15:06:47,753 ERROR [jsp]: Servlet.service() for servlet jsp threw exception
> javax.faces.FacesException: cannot add component with id '_id21' and path : {Component-Path : [Class:
>  javax.faces.component.html.HtmlInputText,Id: _id21]} to its parent component.
>  This might be a problem due to duplicate ids.
