Subject [jira] Reopened: (TAPESTRY-2311) "Parents before Child" concept for Component Rendering does not allow different rendering in subclasses
Date Thu, 17 Jul 2008 11:15:32 GMT

     [ https://issues.apache.org/jira/browse/TAPESTRY-2311?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Fritz Pröbstle reopened TAPESTRY-2311:
--------------------------------------


The *override* functionality works fine if all classes base and subclass(es) are in the same
package.
The overriden function is called for  subclass only.

If base and subclasses are in different packages only the base class function is called. (
It seams as if tapestry did not "see" the overwritten one.

This really seams too be the problem, because if you 
specify the function to be "protected" (at least) tapestry can "see" it and calls the correct
one.

This workaound can be done id source is available for the base class(es) and does not work
if I want to subclass 
core-components.( And naturally this is doen in another package, so this error prevents my
to use the new *Overridíng* feature)

> I   subclassed  GridPager ( public class MyGridPager extends GridPager) to implement
another pager visualisation.
> After creating a MyGrid (public class MyGrid extends Grid) which uses MyGridPager and
copying Grid,tml to MyGrig.tml ist was ready to test.
> Start.tml:
>         <t:mygrid source="tl" row="treffer" rowsPerPage="5">
>                <t:parameter name="regnrcell">
>                  <t:pagelink page="marke2"  >	${treffer.regnr}</t:pagelink>
>             </t:parameter> 
>         </t:mygrid>
> It runs fine - but I got the "old" ,default Visualiation *AND* the   new one.  It is
a result of the "Parents before Child" concept .
> First the Parent creates its visualisatrion the my Child createy its new visualisation.
> Subclasses can not decide of they want to call the implemetation of their parent or not.
> Why is this implemented like this?
> Why call parent implemtation at all, the child could do this explicit by calling super.XXX.(
I know Annotations may make this more complex)
> Can you help ?
