Custom facelets component to include page

[Steven De Groote]

Hi,

I'm in trouble with a fairly basic custom component I built (using JSF1.2 and facelets)
It's the same as the regular ui:include, but it renders its own children if the includefile cannot be found (instread of an exception like in ui:include).

Here is the code of the apply() function within my TagHandler:

		if (path == null || path.length() == 0) {
			log.debug("Path is empty or 0: src=" + src + ";path=" + path);
			included = false;
		} else {
			VariableMapper orig = ctx.getVariableMapper();
			ctx.setVariableMapper(new VariableMapperWrapper(orig));
			try {
				this.nextHandler.apply(ctx, null);
				ctx.includeFacelet(parent, path);
			} catch (java.io.FileNotFoundException ex) {
				log.debug("Failed to include page: " + ex.getMessage());
				included = false;
			} finally {
				ctx.setVariableMapper(orig);
			}
		}

		if (!included) {
			// The includepage was not included, so we render the child tags as a fallback
			this.nextHandler.apply(ctx, parent);
		}

Problem is though, that the code fails on the "this.nextHandler.apply(ctx, null), saying "Parent UIComponent is null.
It doesn't give me an error there when I make sure that the tag does not have any child tags...

Is there any facelets expert around here who knows what I'm doing wrong?
Thanks a lot in advance!
