I figured out if the page starts with 'advancedSearch = false' the image is
always expand.gif and if it starts with 'advancedSearch = true' the image is
always collapse.gif. So the value of Model object is cached somewhere, but
not in the browser for sure.
What I don't understand is that every time the panel is rendered,
getObject() method is called but apparently the return value is ignored.
