//NOTE: Make sure that we dont invalidate the workflow here. Workflow will be invalidated when'
//the designer actions are refreshed on idle thread. Putting invalidation logic here causes the validation
//to go haywire as before the idle message comes in we start getting to DesignerActions thru the paiting
//logic to show smart tags. This causes problems and ConfigErrors appear everywhere on designer intermittently
//PROBLEM: ConfigErrors appearing on the entire design surface
//This is due to a race condition between the validation triggered during painting
//logic and validation triggered when we try to access the DesignerActions from RefreshTask handler
//In the validation logic we try to get to the types while doing so we Refresh the code compile unit
//in typesystem which in turn triggers CodeDomLoader.Refresh. In this we remove types, call refresh handler
//and add new types. While doing this after the remove types but before addtypes, call is made to the drawing
//logic in which we try to grab the designer actions which triggers another set of validations hence now we
//always call UpdateWindow after invalidatewindow so that the validation will always get triggered on painting thread.
//NOTE: PLEASE DO NOT CHANGE SEQUENCE IN WHICH THE FOLLOWING HANDLERS ARE ADDED
//THE PROBLEM CAN BE ALSO FIXED BY TRIGGERING VALIDATION IN RefreshDesignerActions ITSELF
//FOR NOW THE REFRESH FIX WILL CAUSE MINIMAL IMPACT IN THE LIGHT OF M3
