Hi,
I tried to solve the problem and to disable a checkbox with the following
code:
TreeNodeChecked treeNode;
...
UIComponent nodeTypeFacet = getHtmlTree().getFacet(treeNode.getType());
HtmlSelectBooleanCheckbox checkBox = (HtmlSelectBooleanCheckbox)
nodeTypeFacet.getChildren().get(0);
checkBox.setReadonly(true);
...
private HtmlTree getHtmlTree() {
FacesContext context = FacesContext.getCurrentInstance();
UIComponent htmlTree =
context.getViewRoot().findComponent("myForm:idAvailable");
return (HtmlTree) htmlTree;
}
But what happens now is, that ALL nodes of type "treeNode.getType()" in the
tree get read only (disabled).
I expected, that only selected node (treeNode) would get "read only"
rendering.
Has anybody some idea what I do wrong here?
Regards,
Tomek
