Have a look in the ERXComponentRequestHandler. If I remember correctly, basically what happens is a component action url is just a numbered path back into an existing page object in memory. The context id lets the handler know which page to pull from the session
page cache, then the element id is where in the page to find the component action targeted. Something like 5.3.2.4 means context id 5 (page with key of 5 in the cache), with element id 3.2.4 (The fourth element of the second element of the third element of
the parent page). Once that happens, it knows where to call lifecycle methods (invokeAction/appendToResponse/etc) in response to the URL request.
Which means, if you really want to see where the action is executed, look for the invokeAction in the component hierarchy, which appears to be in superclass WOHyperlink.
invokedElement = (WOActionResults)_action.valueInComponent(component);
Where _action is a WOAssociation, probably a WOBindingNameAssociation, where valueInComponent is calling valueForKeyPath on the binding value on the component. That executes the method
and receives a WOActionResult.
I install the Enhanced Class Decompiler plugin to view the code for that. It's a quite nice plugin for eclipse.
Hello,
I have a page component with an action method someMethod(). In the page template, I use this to get the URL for the action method into some Javascript:
<wo:WOActionURL action="$someMethod" />
This is the advertised purpose of that component, and it works as designed.
However, suppose I don't like intermixing component output like that into Javascript in the page template. What I actually want is
just the text output of that WOActionURL component. (Suppose, for example, I want to generate the Javascript some other way, and all I want is that URL itself.) I would have thought that WOContext.componentActionURL() would be the solution—indeed,
somewhere inside WOActionURL that's what is being called. What I cannot see is how WOActionURL is using the 'action' binding to target that method, or, indeed, any way to specify that action method to any of the variants of componentActionURL(). I must be
missing something here—what is it?
