As the title says, but specifically I need to mention, I create the cloner from a python script, and change it to grid array in the same script.. Then later in the same script I make an xpresso node from that same object, and try to create the output ports for Size.X Size.Y , which are attributes only available in Grid Array style.. and they don't show up. :[ If I run the same code to add the ports from a python tag after the python script has run. it will work!! strange...

I'm hoping it will suffice to post a small portion of my source code :

# Create cloner node
xnode_cloner = nodemaster2.CreateNode(nodemaster2.GetRoot(),c4d.ID_OPERATOR_OBJECT,None,600,100)
xnode_cloner[c4d.GV_OBJECT_OBJECT_ID] = cloner
# Add In Ports Size.X Size.Y
print xnode_cloner
xnode_cloner_IN_SizeX = xnode_cloner.AddPort(c4d.GV_PORT_INPUT, \n	c4d.DescID(c4d.DescLevel(c4d.MG_GRID_SIZE), c4d.DescLevel(c4d.VECTOR_X)), message=True)
xnode_cloner_IN_SizeY = xnode_cloner.AddPort(c4d.GV_PORT_INPUT, \n	c4d.DescID(c4d.DescLevel(c4d.MG_GRID_SIZE), c4d.DescLevel(c4d.VECTOR_Y)), message=True)

The strange thing is that the node does not produce the ports.. HOWEVER, if I create a Python tag and then run find the node and run the above commands, then I succeed. So I imagine the problem is that running a python script does not allow the GUI to update the state machine or something?? Because I change the cloner to grid array from inside the python script before trying the above.. and I have the feeling that C4D does not "realize" this has happened...

I've encountered another instance where from inside a python script I cannot do real-time interaction with C4D objects / properties. I think this is related.. If you're wondering what I was trying to do in this other case, it was when I was trying to do Mograph selection from Python. If I tried updating the Mograph Selection Xpresso node inputs from the python script (index, select), it would not update properly, only the last index/select value would be written.. In this instance, I averted my problem by instead doing this from a Python Xpresso node itself, meaning that I created a Python Xpresso Node from my Python script (tedious). But I can't imagine having to go that far just yet for this problem too.. Something's wrong about my approach.

So basically, how can I make this work?? In all fairness, I'm not even sure I've identified the problem.

I imagine someone will say migrating from a script to a plugin will help make this work.. Well I need some guidance as this is my first day / 2nd day in C4D with python. And about 3 weeks in with C4D. Right now I've created a python script that creates a bunch of "stuff" (object, cloner, several effectors) .. And now I'm planning on creating a User Data on the top-most-parent Null object, along with XPresso tag to have the user data control parts of the system I have created.. I'm almost there too, although I have not yet learned to create all of the different user data, such as InExclude. But, that's neither here nor there.

I just run into the roadblock of the cloner Xpresso node not creating the ports, and I believe (starting to re-iterate) done.

here's proof of my ordeal, that might be related.. See how even tho the mode is Grid array, the options are still displaying for Linear?

My hunch is that I shouldn't change the ID property directly but may have to get/set container data.

actually the predicament above was because I have tabs betwen the "View" and "Xpresso Editor" and the Attributes menu does not update properly until the "View" tab is entered.. Strange!! bug report??

Hi,

can you please post some more code? You suspect switching the cloner to grid mode goes wrong, but you don't show any code, how you try to do this.
The tabs issue, I'm not sure I understand correctly. But to me it sounds like an event or update message is missing. Perhaps you can explain this in a bit more detail and post some related code as well?
