Control Internal Evaluation Order Of Dynamic Elements

Hi,

is there a way to control the internal evaluation order? I want to run my expression in a specific order, after the particle dynamics but before the fluid dynamics. So in the sequence: particle dynamics - expression - fluid dynamics. Ordering the objects in the scenegraph doesnt work, i tried to change the NodeState to "Waiting-Normal" for the fluid container, my script got executed and then it did the fluid dynamics, but i just realized the particle rgbPP doesnt work anymore when i do this :confused:

I really have no clue how to do this, but i really need it this way.

Thanks in advance!
