When use dt2-showtable tag in template page, the variables in template could not convert to value.
In the old discussion, I found out that datatable2 tag cannot be used to store data in template. I think it's right.However, it may be work for dt2-showtable tag use in template. Such as add:
$args['where']=$parser->replaceVariables($args['where'], $frame, true )
in '''renderShowTable''' to convert '''where''', '''order-by'''. Is this suitable?
