Problems updating a formLayout

The UI of my script is created when the script is run, and what it does is that it creates a list of objects, using a for-loop that runs through an object array, creating a new iconTextButton per object. Later on in the script, I want to be able to rebuild this UI-part and "repopulate" the list and I was looking into doing this by first deleting the old UI, then call on a rebuild-procedure and last but not least update the formLayout.

All of this is working except for the final part: updating the formLayout.

	formLayout -edit
			
		-attachControl 		secondFrame 		"top" 		0 	firstFrame
		-attachForm 		secondFrame 		"left" 		0
		-attachForm 		secondFrame 		"right" 	0		
		-attachControl 		secondFrame 		"bottom" 	0 	lastFrame
			
	myLayout;	
Generates this error:
Error: line 8: Object 'secondFrame' not found.

...which is a lie because running "deleteUI secondFrame" deletes the UI object. If the object didn't exist I wouldn't be able to run that command, so why is Maya complaining?

The reason I need to do that edit to this formLayout is that I need to re-attach the secondFrame UI-object to the lastFrame UI-object. Right now everything in my script is working except for this final part (as I wrote above), and I end up with a large gap between the second and third frame.

Without seeing the whole code, this is the only thing that comes to mind:

is 'secondFrame' a direct child of the formLayout? It must be in order for the formLayout to consider it a valid control.

Spot on Nyro - that did the trick!
I had parented it to the firstFrame instead of parenting it to myLayout as you suggested.

Yeah, the coders eternal nightmare: confounded by a problem, expecting a complicated bug, solution turns out to be trivial
