Very simplified version of rich tree with list data source still giving me a blank page...

[Matt Kohanek]

Instead of using my code that is rife with potential erros, I decided to simplify things to determine if it was just in the way I was binding my list to the rich tree. ANd in its most simplified form I am still getting just a balnk page.

Here is what i did:

First I made a simple class to declare a list, populate it with one entry and have setter and getter:

public class RootNodes {

	List<String> ids  = new ArrayList<String>();
	
	public List<String> getIds() {
		ids.add("Test");
		System.out.println(ids);
		return ids;
	}

	public void setIds(List<String> ids) {
		this.ids = ids;
	}
	
}

When I printed out the value of ids it printed out [Test] so it seems the list is getting the value, and should not be null. SO I created a managed bean, and then tried to bind ids to a tree:

<ui:composition xmlns="http://www.w3.org/1999/xhtml"
      xmlns:ui="http://java.sun.com/jsf/facelets"
      xmlns:h="http://java.sun.com/jsf/html"
      xmlns:f="http://java.sun.com/jsf/core"
      xmlns:a4j="http://richfaces.org/a4j"
      xmlns:rich="http://richfaces.org/rich">

    <h:form>    
        
            <rich:tree style="width:300px" switchType="ajax" >
            <rich:recursiveTreeNodesAdaptor nodes="#{nodesBean.ids}" />
            </rich:tree>


    </h:form>

</ui:composition>

But all that does is print out a blank page, just like my other code up there. This is as simple as it can get, so I must be missing something about how to bind this to a treeNode. Can anyone tell me what Im doing wrong?

Im kind of thinking I might need more java code. Maybe something needs to invoke the getter method so it will first add "Test" to the ids list? That is really all I can come up with though.


edit:

I even simplified it a bit further by doing this:

int[] ids = {1, 2, 3, 4};

	public int[] getIds() {
		return ids;
	}

	public void setIds(int[] ids) {
		this.ids = ids;
	}

ANd still a blank page. However, I did change nodes="#{nodesBean.ids}" to roots="#{nodesBean.ids}" and I did get a one branch tree with a value of
[I@1486306
Not what I was looking for, but compared to the luck I have had with this it is almost a miracle

I just needed to change nodes="#{nodesBean.ids to roots="#{nodesBean.ids
and also create a void method to do the adding of the values to the list, then call that method in my getIds method and now it works.

On a side note I have never seen the jsf forums so dead (I know I have only been a member since april but still)
