Hi, 

Ok invoke is another thing. Meanwhile I did write some custom actions. What I 
am doing is trying to call the object from within the actions.
I managed to get an instance to the object by passing a reference to it in the 
event trigger method in my client code. I then access the parent context inside 
the custom action and get the '_eventdata' object.

I was trying to define a variable with the <var> element inside the <onentry> 
element but the engine warned me it was ignoring it. Do you know why ? I saw in 
the datamodel section of the site that you can define them. (Although there is 
not a word of it in the 2011 w3c spec)

Sorry for my ignorance and dumb questions but I am very new to all this.

Thanks
Daniel Santos
