Bug: TWikiVariables don't seem to display consistently in templates

There seems to be some difference between different types of variables, and the way they are displayed in templates.

I like to create new pages based on semi-built templates, such as in the NewBugTemplate for creating a new BugReport. In the NewBugTemplate example, there are some TWikiVariables such as %DATE% and %WIKIUSERNAME%. When a new bug report is created using that template, I see something like this:

 -- Main.RossC - 16 Oct 2002 

when editing the new bug report. However, let's say I want to track the time of the bug report creation, so I include the variable variable %GMTIME% (or %SERVERTIME% for that matter) in the NewBugTemplate. In this case, I see:

 -- Main.RossC - GMTIME 

i.e. the variable is not expanded to its value. ( Yes, the appropriate % signs do show up. Still struggling here with VerbatimExpandsVariables)

Why does this happen 'correctly' for the %DATE% and %WIKIUSERNAME% variables, but not for some others?

Test case

Environment

-- RossC - 16 Oct 2002

Follow up

The current spec is that only %DATE%, %WIKIUSERNAME% and %URLPARAM{...}% are expanded, and %NOP% is removed.

There are cases where other variables should get / should not get expanded. See related topics MoreExpansionInTemplateTopic, ExpandUrlParamForNewTopics
