[TRINIDAD] Javascript sendPartialFormPost - how to read param in bean

[Elmar Kretzer]

Hi everyone,

when i am triggering a partial submit via javascript and add e.g.  
param1 to the call,
how can i read the value of the param in the bean from the  
FacesContext ?

Javascript Code:
TrPage.getInstance().sendPartialFormPost(
     theForm,
     {param1: "value1", param2: "value2"});


any clues?

Thanks in advance
Elmar
