Dave,
Thanks for the help here. I see the same thing happening now.
If I have a leading slash in my config file I can create a link with both
and action and a url but the action tag then only works if I have a leading
slash. If I dont then I get the 'cannot find action' error.
I can create a url tag with or without a leading slash.
If I dont have a leading slash in the namespace attribute in the config file
I cannot create a url at all.
It may be inconsistent. It maybe documented that way. It may be the case
that this demonstrates the correct semantics for both the url and action
tags, I don't know. I do know that I can make progress now and that makes me
happy.
I do wonder if this is correct. I am gonna have a good long look at docs
again and see.
Thanks all for the feedback. Especially Dave N.
