If I have a component that is rendered by an ActionEvent, how to I keep the component rendered on the page if I rerun the even?

[Todd Patrick]

I have the following tree2 (that is working... horray!) that is displayed based on a call to an ActionEvent:

 

<t:tree2
id="clientTree"
value="#{tbrowser.treeData}"
var="node"
varNodeToggler="t"
showRootNode="false"
rendered="#{tbrowser.displaytree}">

 

In my backing bean, I have the following code defined:

 

private boolean displaytree;

 

public boolean isDisplaytree() {
    return displaytree;
}
   
public void setDisplaytree(boolean _displaytree) {
    this.displaytree = _displaytree;
}

 

public void transTypeSelected(ActionEvent event) {

...

    this.displaytree = !this.displaytree;

    FacesContext.getCurrentInstance().renderResponse();

}

 

When I click on the h:commandButton:

 

<h:commandButton value="Search" actionListener="#{tbrowser.transTypeSelected}"/>

 

Everything displays as I expected.

 

The second time I click on the h:commandButton, I return an error "java.lang.IllegalArgumentException: Unable to locate facet with the name: index"; which basically breaks my TreeNodeBase:

 

TreeNode treeData = new TreeNodeBase("index", "Transactions", false);

 

I believe that after I set the displaytree value (rendered) to true then back to false, my Java tree code can't find the tree2 component.

 

Thoughts on how to fix this, do I just refresh the tree? How do I accomplish that?

 

Thanks,
