xfoms:dispatch problem

> The basic functionality is to have a XForms instance in a certain structure
> containing maybe some hundreds of parameter to be editable by the user. This
> Xforms instance is organized in a way that a navigation tree can be derived
> with XForms to select subnodes of the whole instance to let edit the user
> some parameters also by XForms.

> Enclosed I have the whole application (except the OPS lib directory) but
> disabled most of the function by comments to isolate one of my problems

> This problem is in my XForms tree implementation that is based on
> xforms:repeat.

> The selected "record" within a repeat is shown in yellow as somewhere

> way to get information what record is selected with the exception of
> defining a trigger containing a dispatch action to set a node with
> information of the selected "record". This trigger is also doing the

> If you run the application to move from one tree item to another takes on my
