[rules-users] Updating a Boolean object in the WM

[skasab2s]

Hi guys,

I've been desperately trying to update a Boolean object, which is in the
working memory.

I have an initial rule that  first inserts it:
rule "Insert initial weanable value" salience 100
	when
		
	then
		Boolean $weanable = false;
		insert($weanable);
end

and then I try to update it:
       ...
       when
               $weanable: Boolean( )
               ...
       then
               	$weanable=true;
		update($weanable);
end    

Which results to this exception : org.drools.FactException: Update error:
handle not found for object: true. Is it in the working memory? 
I checked in the working memory and the Boolean-object was there!


Is it possible to update a boolean that is in the working memory? If not, do
you know some other Java class with setters and getters (behaving as a
drools-fact) that I don't have to create myself and which I can use instead
of Bboolean for this case ? 

Thanks in advance!
