Using a formfield in a parametric INCLUDE does not work. The % parser seems to get confused about tags with parameters in parameters of tags.


%INCLUDE{"RenderTopic" NAME="%TOPIC%" HEADLINE="%FORMFIELD{"Headline"}%"}%

The parser is fine, but %FORMFIELD renders the form field before it returns it. I can't see why it should do that, so I have removed it, and it all seems to work now. SVN 6073 CC

This isn't fixed completely: if a %FORMFIELD is a textarea with linefeeds in it then the %INCLUDE will not happen. Sorry, reopend this bug again.


It is fixed completely, as far as the spec of TWiki variables is concerned. No variable allows parameters that contain newlines, and the rules for expansion are quite clear; inner, then outer. If you change the way the parser works, it will be incompatible with Cairo and a lot more than this one example will break.

I agonised long and hard over this, and ended up with what seemed to be the solution most compatible with existing Cairo TWikiApplications. If you still don't agree, then we need to redefine TML, and you should raise a change request in Codev, as it is beyond the scope of a bug report.


CC, should this item be reopended again according to your comments on irc?


No, because the current semantic is consistent with Cairo. if we change the semantic, we confuse people a hell of a lot more than if we don't. Every time I have tried to change these stupid semantics, I have had kickback from PeterThoeny, and I just can't be bothered having the argument again.

Note that this isn't the only stupid syntax/semantic. The way parameters to TWiki Variables are parsed stinks.
