This is a wild guess but if anything works I think the best bet would be through the lang files.
Adding a help element for that property in the same manor as in the <common>-node but for the newslist page type further down or in a "later" lang file could work.
Thanks but unfortunately it doesn't work. I added following node to a "later" language file but the help text didn't change.
<help>new help text</help>
OK, good to know.
I guess you will have to settle for changing the text for all to something like "When using Nyhetslista this controls behaviour x for other pagetypes it controls y".
Thanks. I did it as you suggested.
Hi, does anybody know how to change help text of built-in property for specified page type? For example, I have a page type "newslist", I only want to change help text of property "PageChildOrderRule" for page type "newslist".
