Subject [jira] Commented: (TAP5-5) Context lost in a form fragment in a property editor component
Date Tue, 03 Mar 2009 22:38:56 GMT

    [ https://issues.apache.org/jira/browse/TAP5-5?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12678494#action_12678494
] 

Howard M. Lewis Ship commented on TAP5-5:
-----------------------------------------

I think the proper solution would be to have a non-visual component that could be placed inside
the FormFragment whose job is to re-synchronize the PropertyEditor at submission time.

> I created a PropertyEditor to edit a special class, which content spans over one or more
pair of String. 
> The TML for the PropertyEditor declaration is :

> 		                           messages="prop:context.containerMessages"/>
> </t:block>
> The TML of the property editor itself is : 
> <t:label for="s11"/> <t:textfield t:id="s12"/> <br/>

> If I try to read / update the myPropery parameter in that class : 
> - from the s11, s12, s21, s22 getter or setter -> everything works ok, I can read
or update this parameter
> - from the t11, t12, t21 or t22 getter or setter, I get the following stack trace :
