Judging from the source in DocumentTemplate.DT_In.py and DocumentTemplate.DT_InSV.py, it APPEARS that the handling of 'sequence-query' is buggy. It looks like in InClass's constructor, it will define the regular expression 'start_name_re' only if the 'start' attribute was specified AND the value for 'start' is non-numeric. Makes sense since it will remove that variable from the query string if it exists. However, the sequence_variables class will raise an error if 'start_name_re' is not defined when trying to get the value of 'sequence-query'. Shouldn't I be able to get the value of 'sequence-query' if I do something like: <dtml-in some_list start=5> ... Perhaps this is the intended behavior? Does it not make sense to be wanting to look at 'sequence-query' if I'm specifying a constant 'start' value? Both 2.1.x and 2.3.x versions handle 'sequence-query' this way. Thanks, Erik Stephens
