Custom command link in renderer

Question

Hello, I have created my own custom tree renderer that displays a tree structure on screen. For each node, I want to generate a command link that is bound to a single method in my backing bean. I am trying to use writer.startElement and writer.writeAttribute for this, but I don't know how to code the actual method binding. Here is what I have so far:
writer.startElement("a", component);
writer.writeAttribute("href", "#", "href");
writer.writeAttribute("onclick" document.forms['workArea:subview1:treeTestForm'].submit();", "onclick); writer.write("My Node Label");
writer.endElement("a");
However, clicking this link submits the form, runs my encode method again and then runs my decode in the renderer. How can I write attributes to this link so that a single method in my backing bean is called each time a node is clicked?

Answer 1

Basically what I'm doing now then is creating a MethodBinding in the decode method, so that it calls a method I'm looking for when the row is clicked. I have two problems now:
1. The encodeBegin method is called again in this instance and I only want it called once when the component is first rendered. Is there a way to only allow it to run once?
2. My ID is not being passed back in the UIComponent argument, even though I am setting it in the ResponseWriter.
I read that the basic syntax for command links is:
document.forms['CLIENT_ID']['CLIENT_ID'].value='CLIENT_ID' but when I view source on some of my other pages that use the h:commandLink tag, the second CLIENT ID reads : '['__LINK_TARGET__']. and I have no idea where that is coming from.
Any ideas?
