States and visualstatemanager

Anyone got any good info on these subjects, seems like theres nothing out there at all of any use.

Basically we’re trying to change the state of a control when a certain event happens (in this case a page scanning or a document uploading)

We’ve managed to change the states though blends built in gotostateAction through a mouse click, but we cant get it to change (well we have but it doesnt change visually, which is kinda the whole point!)

any clues would be much appreciated!
