RE: Using a TreeModel for Menu State - Best Practice to send statechanges via Struts

[Brian Hart <BH...@MAIL.NYSED.GOV>]

Remove the Tree Model from the equation then, this isn't a question about rich client UI.  The Struts specific question is how to pass parameters to the action class (and access them in the action class code)via the <html:link action="menu"/>  tag without a formbean or form submission taking place.  I want a group of links to share the same action class and pass parameters into the ation class to correctly trigger some behavior.  This is primarily a request for content based on the menu action.  See below:

<html:link action="/menu?menuID=20&content_id=30">Arts</html:link> 
<html:link action="/menu?menuID=10&content_id=30">English</html:link> 

Is the above valid approach?  How do I get access to these parameters in the action class?

This is what we are waiting for in Java Server Faces to bring server side 
action to rich client side interface with easy to use Tags.

Subject: Using a TreeModel for Menu State - Best Practice to send 
statechanges via Struts 


The TreeModel interface and DefaultTreeModel implementation of the JDK 
provide the necessary functionality to manage the state of a tree which will 
be managed in a set of database tables. We will be rendering the state of 
the tree in HTML. My question is how to build the HTML links to correctly 
communicate which link is clicked in Struts 1.1 RC1. I picture a single 
Action class, something like MenuAction that would then get a set of 
parameters indicating the node clicked and then delegate to the business 
object to update the TreeModel accordingly. Much of the documentation is 
about using ActionForms to pass information to the Struts Action. Without A 
Formbean how does one correctly use the action attribute of the <html:link> 
tag in struts 1.1? 

<html:link action="/menu?menuID=20&content_id=30">Arts</html:link> 
<html:link action="/menu?menuID=10&content_id=30">English</html:link> 

Tree could be something like: 
Arts 
Music 
Learning Experiences 
Theature 
Best Practices 
ELA 
Learning Experiences
