create EventLink without onPassivate

Hi all!

I use ComponentResources to create my EventLinks. As the page context 
(in this example "id") is added to the link onPassivate gets called. 
This results in a link like

     /mypage:mycomponent?t:ac=id

Each component context "cc1", "cc2" passed to the createEventLink method 
results in a link like

/mypage:mycomponent/cc1/cc2?t:ac=id

My goal is to replace the exisiting ac, means the activation context of 
the page which is used in onPassivate to create "arbitrary" eventlinks 
like this

/webui/mypage:mycomponent?t:ac=ec1/ec2

without accessing the page members prior link creation. Of course it's 
possible to convert the Link to URI / String and perform some string 
manipulations, but I wonder if there is a "real Tapestry" solution?


Thanks in advance

Jens
