onChangeImpersonated
This event is triggered whenever the user changes which token is impersonated.
As a frame-based event, a frame containing the event code has to be opened.
Set up
Create a frame that has this special html tag in it:
<link rel='onChangeImpersonated' type='macro' href='macroLink'>
Replace macroLink by an actual macroLinkText-call to a macro of your choice (the returned value of macroLinkText()). A common practice is to call the frame opening macro itself to actualize the content.
No arguments are passed to the event, so to find the impersonated token we have to call getImpersonated():
[h: vImpersonated = getImpersonated(1)]
