Bug: validator variables in a form are being changed during unrelated widget change

[KeyWorksRW]

Description:

If you change a widget type to a different type, and all validator variables in the form are treated as duplicates and get a number added to the end of the variable name. The easiest repro case is to change a wxComboBox or wxChoice into the other type in the wxUiEditor New Dialogs folder (e.g., NewDialog).
