[opencms-dev] <cms:contentload>-tag and no collector results

[Marcus Popetz]

I believe they don't skip the body because you'll never see the "add new 
content' icon if you don't have at least one...it's a nastiness of the xml 
content stuff.

So, you have to create one manually which is a pain (check out the examples 
to find a xmlcontent you can use to create your new one).

Here's something I did to help work around this problem.
