Hi there,
I'm trying to use Runtime.releaseObject to delete objects from a page.
I use Runtime.evaluate as discussed before in these emails to find the
object and objectId and then call Runtime.releaseObject on that
object.
I expect the memory of the object to be released. Also I expect if I
use Runtime.evaluate again to find the object, it does not find it
again. But neither of this happens; not the memory is released not the
object is deleted. Calling the function again can find the
corrresponding object.
Any help in this regard would be appreciated.
