RE: Parsing CFML from a database field

[Francisco Montes; Spain on Line]

Thank you for your comments.

As i see, any references to variables in your cfcode are resolved before
anything else. In your first example that is not a problem as they�re
assigned a value beforehand. Then you cfoutput the cfcode variable but
unfortunately is taken as a literal string and handled as such without being
parsed again (as the parsing phase has already finished with it!). That�s
why if you look at the HTML source of the output page you get <cfoutput>
tags in it. Had they been parsed for second time (which is what i wanted)
you would had got that error message we all get when we try to nest cfoutput
tags... :-(
