[Seaside] lightbox with WATask

this is definitely a bug. I added a report to the bug-tracker.

It occurs because the lightbox decoration also tries to render the
component that is initiating the lightbox. In the case of a task this
doesn't work (the task itself has no visual representation).

I don't see a simple solution right now. Generally I suggest to use
WATask sparingly. If possible define your flow from a component using
a callback. This is does not show this bug and is more efficient as
well.

Cheers,
Lukas
