I have a SimpeMod modifier, which has a rollout, that has a dropDownList. I can't directly associate a parameter from the rollout with a dropDownlist in the user interface, so I have to store the index and the string for the selected object. (ui:)

When the user selectex a item in the list, I store in a local variable the selected item, and the index of the item. But, when I select a different object in the scene, and then select the first one again, the rollout appears with the default selection value defined for the rollout. I don't know how update the list when I select the object so in the user interface the dropDownList is showing the item that I stored in the local variable as selected, and not the default one...
