My second problem is not related to printing but interresting anyway, at least

to me... :-)

Is there an "official" RV way to handle the situation when the components

are containing data not related to a published field. (I guess that's the

case in the TChart demo: When saving the demo page containing the data-filled

charts and loading it back, the data is gone...)

My own solution is adding a persistent stream to the component, and saving

the data to this one BEFORE saving the rvf, and later reading the data back

from the persistent stream for each component AFTER the rvf is loaded.

Is there a simpler way? Would it be possible to extend the demo whith this

kind of "saving and loading charts pages containing chart data"-functionality?

Reagards, and thanks for a superb product! / Jonas
