Igor,
This was great. Exactly what I needed. I applied this to my TextField and
DropDownChoice with a few tweaks and it's perfect. But when I went to do
the same to TextArea, I am told that onComponentTagBody is final and cannot
be overridden.
So i tired without that method overidden like so:
public void onComponentTag(ComponentTag tag) {
super.onComponentTag(tag);
if (!isEnabledInHierarchy()) {
tag.setName("label");
tag.remove("type");
tag.remove("value");
tag.remove("disabled");
tag.setType(TagType.OPEN);
}
}
// public void onComponentTagBody(final MarkupStream markupStream, final
ComponentTag openTag) {
// if (!isEnabledInHierarchy()) {
// replaceComponentTagBody(markupStream, openTag,
getDefaultModelObjectAsString());
// }
// }
And that produced the following exception:
org.apache.wicket.markup.MarkupException: Component [narrative] (path =
[4:oagForm:narrative]) must be applied to a tag of type [textarea], not:
'<label wicket:id="narrative" name="narrative">' (line 0, column 0)

I love this technique as it is so clean and direct to the problem. How can
I make it work for TextArea?
