Tree Node and Ampersand
Hi,
I need to place ampersands in tree node text property. To get the text
rendered right I need to provide the text as, for example, Bed '&+amp+;'
Breakfast.
This tree node is rendering well in the browser as "Bed & Breakfast".
But if an action is associated with the tree node and I run the app
the tree node is rendering to "Bed '&+amp+;' Breakfast".
"&+amp+;" means the well formed XHTML for ampersand, if I had written this as it should be it would render in this post as &.
Is there any workaround?
Thanks.

The Tree Node is now rendering right, but I run into another problem. After selection I need to display the Tree Node text in a static text component. which worked with this code:
public String node_action() {
String fullId = tree1.getCookieSelectedTreeNode();
String id = fullId.substring(fullId.lastIndexOf(":")+1);
TreeNode selectedNode = (TreeNode) this.getForm1().findComponentById(id);
String category = selectedNode.getParentTreeNode((TreeNode) selectedNode).getText();
if ( category.indexOf("&") != -1 ) {
getSessionBean1().getClassified().setCategory(category.replace("&", "&"));
}
else {
getSessionBean1().getClassified().setCategory(category);
}
String subCategory = selectedNode.getText();
if ( subCategory.indexOf("&") != -1 ) {
getSessionBean1().getClassified().setSubCategory(subCategory.replace("&", "&"));
}
else {
getSessionBean1().getClassified().setSubCategory(subCategory);
}
categoryTextfield.setText(getSessionBean1().getClassified().getSubCategory());
categoryTextfield.setVisible(true);
return null;
}
}
(some & in the code section are original meant to be the XHTML for ampersand.)
but for the few Tree Nodes which are prerendered now, the call
String subCategory = selectedNode.getText();
returns null.
How can I get the text of for those prerendered Tree Node?
Thanks.

It depends on when you invoke selectedNode.getText(). If it is before prerender() is called, it may returns null. I'd suggest to bind the tree node's text property with a bean property which has the string "Bed & Breakfast"
<ui:treeNode action="#{Page1.treeNode1_action}"
binding="#{Page1.treeNode1}" id="treeNode1"
text="#{SessionBean1.treeNode1Test}">
<f:facet name="image">
<ui:image binding="#{Page1.image1}"
icon="TREE_DOCUMENT" id="image1"/>
</f:facet>
</ui:treeNode>
