### PGML: preformated text in a list

by Jan Hlavacek -

I am trying to create a numbered list in which each item contains a line or two or preformated text. I tried this
1.  This is a text in the first item

:   This should be preformated and can has [\$variable]s

And this is still a part of the first item

2.  This is the start of the second item

:   And this is again preformated

The end of the second item

and so on, but it does not render and gives me a cryptic error message:
Can't call method "combineTopItems" on an undefined value at line 222 of [PG]/macros/PGML.pl

Is there any way I can place a block of preformated text with variable substitution in a list?
