Thanks for the hint... I did look into the source code and could figure out
the onComponentTagBody trick, too... replacing this with text is one
thing... but wrapping other components would not be as easily done (as far
as I am able to grasp this - correct me if I am wrong) - that's why I
brought up the ImageLink use case, too. Is it a good idea to add child
component tags to the component tag body programmatically and adding the
component instances later on, in onBeforeRender?
Cheers :)
