[opencms-dev] set widget parameter of self-made widget, reading property of resource

[Andy Bicksbo]

HI
May set the Listener to null and may call the garbageCollector.
Build a loop which sets it to null if nothing is checked.
But i don't know if there are some bugs...but for my expirience the opencms
source is very structured and doesn't provides code which will not work,
maybe a few methods should be set to pulbic ;)
