[Closed] Can't create rollout with execute in Scripted Material Plugin

I am trying to make a material plugin via the scripted plugin system in MAX.

I have been able to create the basic functionality I need using the standard structure explained in the documentation. However, I want to dynamically add content described in the following example with a for loop, either by creating the rollout with an execute function or via the rolloutcreator tool.

  plugin material EasyDecal
  name:"Easy Decal"
  classID:#(695425,446581)
  extends:Standard replaceUI:true version:1
  --Place no#1
  	( 
  		parameters main rollout:params
  			(
  				MBdiff 							type:#texturemap ui:MBdiff
  			)
  		--Place no#2
  		rollout params "Decal Parameters"
  			(
  				mapbutton 	MBdiff 						pos:[16,16] width:212
  			)
  	)
  

The problem seems to be that you cannot use execute or the rolloutcreator at either location described above.

Here is some examples of some things I have tried:

Place no#1

  str = "(
parameters main rollout:params
(
MBdiff 							type:#texturemap ui:MBdiff
)
rollout params \"Decal Parameters\"
(
mapbutton 	MBdiff
)
)"
  execute str
  

Place no#2

  paramsRCI = rolloutCreator "params" "Decal Parameters"
  paramsrci.begin()
  paramsRCI.addControl #button #BtnSourceFolder "Show Maps Folder: " paramStr:"align:#left"
  paramsRCI.end()
  

&

  str = "rollout params \"Decal Parameters\" (
edittext MapFolderLocation)"
  (execute str)
  

I figure this could just be an issue of scope but I doubt it. I’m guessing that if there is a work around it will be something that isn’t apparent. I am guessing that I will have to define the rollout externally and then call it somehow within the plugin but there doesn’t seem to be any help on how to do that.
