How do I set the EXPRESSION_PRIORITY of a plugin expression?  I see it uses a customdatatype PRIORITY.  This consists of a LONG which is a set of enumerations for the evaluation priority ( expression, generator, etc... ) and a GeData which is also a long defining chronological placement in the priority list.  I think I would retrieve the customdatatype from the container and set it back using the specific datattype function.  Doesn't seem to work here.  Any examples would be very helpful.

Have a look at the LookAtCamera.cpp example in the SDK example files.
Use AddToExecution to add your point of execution to the execution list.

That is what I am already using.  I specifically wanted to know how to do it the other way ( setting customdatatype parameters ).  Thanks anyway.

Isn´t that what LookAtCamera.cpp exactly does? Maybe I am misunderstanding you:
GeData d;
 if (node->GetParameter(DescLevel(EXPRESSION_PRIORITY),d,0))
 {
  PriorityData *pd = (PriorityData* )d.GetCustomDataType(CUSTOMGUI_PRIORITY_DATA);
  if (pd) pd->SetPriorityValue(PRIORITYVALUE_CAMERADEPENDENT,GeData(TRUE));
  node->SetParameter(DescLevel(EXPRESSION_PRIORITY),d,0);
 }
Or what exactly do you mean by setting customdatatype parameters?
maybe my english is just bad :o)

Well, you are correct in the second email.  When I downloaded the updated SDK the lookatcamera tag source has changed.  That is what I was looking for.  You first email was speaking of the AddToExecution function which I was already using.  Thank you for the pointer.

Oh sorry, that was only an add-on. I thought probably you need this function too if you are dealing with the execution list. My fault.
