I have a IN_EXCLUDE list that contains splines (parametric or freehand)
I need to check if any of these splines changed. If it changed position, rotation, scale, point position or, if it is a parametric spline, if any of the parameters changed.
I tried using IsDirty but it is not working.
How can I check for any change in the splines of the list?

It's not the most elegant solution, but you can cache all of the data you want to watch, and then check for changes anytime C4D sends an c4d.EVMSG_CHANGE message via CoreMessage.
If someone knows of something cleaner with less overhead, I'd love to hear about it.

I found a way. I will post it here tomorrow. It is very late here now.

Here is what I did:
I created a global variable (actually, a variable that exists only in the scope of my plugin class) named "old_changes" and initialized it to zero.
then, in the GetVirtualObjects method, I used some code similar to this:
for i in range(count) :
if obj is not None:
new_changes+=obj.GetDirty(c4d.DIRTYFLAGS_DATA) + obj.GetDirty(c4d.DIRTY_MATRIX)
Comparing "new_changes" and "old_chages", if they differ, something was changed in the objects of the list.
Finally, of course, I set "old_changes" to be equal to "new_changes"
