[WWdevel] Re: [WWcvs] webwork-modperl: Commented out escapeHTML() of warning messages since it

[Michael Gage]

I'm not sure how to resolve this.  We use "warn" routinely inside 
problems to
help write and debug problems.  pretty_print_rh formats complicated
structures in tables.  This is very useful and I'd rather not loose it.

Hard coded warn messages can have < > manually replaced by < and

there is a problem if the warn message has a variable.

I suppose that the long term solution is to build a protected print or 
debugging statement
within the PG environment that allows us to produce debugging output 
without using the warm
mechanism.

For now I'd like to leave it the way it is, with HTML allowed in warn 
messages, and you have to
do your own escape.  If this causes too many problems I'll up the 
priority of finding another method
for reporting debugging errors in problems.

Take care,

Mike
