Mark Cave-Ayland commented on RF-12611:
---------------------------------------
After a little bit of work, I've managed to set up a suitable development
environment on my workstation which is capable of building RichFaces from
source.
I can now confirm that making the following change to requiresRowIteration() in
UIDataAdapter.java allows my embedded row-level composite component to function
correctly within rich:dataTable:
private boolean requiresRowIteration(FacesContext context) {
return true;
}
I'm not necessarily confident enough in this as a solution to submit a formal
patch (it may have other side-effects I am not aware of), but I thought I
should document it here anyway.
> rich:dataTable doesn't call restoreState() on a row-level composite component

> Key: RF-12611
> URL: https://issues.jboss.org/browse/RF-12611
> Project: RichFaces
> Issue Type: Bug
> Security Level: Public(Everyone can see)
> Components: component-tables
> Affects Versions: 4.2.3.Final
> Environment: Debian Wheezy, Linux, amd64
> Reporter: Mark Cave-Ayland

> I currently have a row-level composite component that works well within a
> h:dataTable which I am looking to migrate to rich:dataTable for more
> flexibility with layout. However when embedded within a rich:dataTable, the
> component state is not preserved during the RESTORE_VIEW phase.
> Further investigation with a debugger shows that the problem is within
> UIDataAdapter::restoreState() in that requiresRowIteration() returns false
> during the RESTORE_VIEW phase, and so the restoreState() function within the
> row-level composite component is never called.

> Many thanks,
> Mark.
