OpenDCL Document Events

The VLR reactors are pretty limited when going from document -> lisp interpreter -> OpenDCL.arx.  I guess it's because of the interpreter, objects don't get released during CommandEnded, AttachEnded, and DataBase call-backs.  Or maybe it's because dcl_Functions are commands?

In any event, it would be nice if OpenDCL had some built-in event handlers.  The ones I've had the most trouble with are when Objects are added or removed from the Drawing Database.  Most of the others work fine: CommandEnded works for most Object Table update functions.  Obviously, this would be for Modeless, Dockable and Palette forms.  These forms need to react to the Documant environment real-time.  Right now I have refresh buttons when reactors aren't working.

Maybe:
dcl_objectAppended
dcl_objectUnAppended               
dcl_objectReAppended
dcl_objectErased
dcl_objectUnErased

Any thoughts?  Any others?

Events related to switching documents would be on my list.

I haven't yet tried using

:vlr-documentBecameCurrent
:vlr-documentToBeActivated

although I may try it this weekend.

Scenario:

Modeless form which needs to use a document-specific variable (either a LISP global or a dictionary variable) to update the value displayed by a control.

Anyone have any experience to share on this topic?

The modeless forms have an "OnDocActivated" event for that.

It would be helpful if you could post some sample code that demonstrates the problem.

I'll put an example together.
