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?

No... jFreeChart when it renders its graphic has its own classes to render the associated URL while it does that.
So I can give it a context and any text.. probably pass it an eo too. That is about it.


Do I have to create and insert context.elementIDs through each iteration jFreeChart does?

confused.

Yeah, me too! :-) In that case, I think that what you want is to do is to create the URL once and append something like ?projectID=123 to it. Then, in the action method, get the projectID form value, use EOUtilities.objectWithPrimaryKeyValue to convert 123 to an Project EO, then return a page showing that. It will be similar to a direct action with a query string / parameter, but it will hit an action method instead of a direct action. Does that make sense? Will that work with jFreeChart (I have never used that)?


Chuck



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.

Hi James,

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
