Chuck -
I have been reading and re-reading that section. And, I still can't
seem to grasp one
fundamental issue and that is how I am to relate my current
EOObject to the action.
Each bubble on my graph is a project. Clicking on a bubble popups
the project window.
So...
They are in a WORepetition, right?
I can see how to construct the URL, even invoke an action, however,
I am still mystified
about how it is to know what object the URL is referring too. Does
this make sense?
All that you can know is that the URL is for the current item in the
repetition. The URL is not for a specific object, just for a
specific place in the iteration through the tree of WOElements. So
in your invokeAction method, when context.senderID().equals
(context.elementID()) then whatever is bound to the 'item' of the
WORepetition has the correct Project to popup a window for.
I am also not clear on why you don't just use a WOHyperlink for this.

I need to construct a componentActionURL vs a directActionURL.
Basically I am using jfreeChart and need to create a popup of an
object.
I can make it work great with direct actions however, for reasons
unimportant here,
I need a componentActionURL.
My question I think is how to set the action for
WOContext.componentActionURL?
I think you are thinking about this backwards. The frameworks
compute the URL based on where in the tree of WOElements it is.
You don't set the action. The question to ask is, "How do I know
if the incoming action is for me?" The answer is to check if
context.senderID().equals(context.elementID()). See page 181
