Slight problem with custom output records

This is got to be something trivial I'm missing. I have my own custom output
records within my pane's coordinate-sorted-set and if I manually do a replay
to those records they display themselves appropriately after I do a
window-set-viewport-position*, BUT if I scroll that pane via the default clim
scroll bar, my presentations disappear and they don't redisplay themselves.
But then if I manually invoke replay on it, it appears appropriately offsetted
according to the new viewport position.
If I manually do replay on the coordinate-sorted-set for that pane that
fails also! So what tie-in am I missing between my pane's top level output
record and my output-records? My output-records are elements to that
coordinate-sorted-set and the coordinate-sorted-set is a parent to my
Well, your records might be incorrectly mainting the position/size
info used by output record replay to test for the record being
visible. Look at (describe) the records and see if their bounding
boxes and output-record-position* values look right.
Trace CLIM::REPLAY-1 and see if it gets called on your records.
My output-records have presentation, output-record-mixin,
output-record-element-mixin, and displayed-output-record-element as mixins.
In what order?
Are your new records going to be "leaf" records, or will they have
children? Oh, I see, they are supposed to be presentations and
therefore may have inferiors.
Why not just subclass the STANDARD-PRESENTATION class? That will get
you all the standard behavior. What characteristic of presentation
behavior are you trying to change?
