I'm having a struggle to pin point the run-time error with this.
I have narrowed it down to in being caused by a test="" statement, with a
quick search of the net. But I cannot see any problem with any of my test
statements.
Could someone see if they can spot the bloomer!
test="$image-node-list"
-- Requires a return of true if list is not null.
test="not($image-node-list)"
-- Require a return of true if list is null
test="($finish - $start) = $images-across"
test="$start = $finish"
test="$start < $finish"
-- Obvious returns, all values are numbers.
test="$image-node-list[$start]/link"
-- Requires true if link node exists
test="$image-node-list[$start][position() = last()]"
-- Require true if the node at position $start is the last node in node set
As always, all help greatfully recieved.
Cheers
Simon

Subject: [xsl] RuntimeException : Programmers's assertion from xsl transform
Hi all,
I am getting a run time error from an xsl transform, but I don't have a
clue
what this means. Any help would be greatfully recieved. I've included part
of the code where I think the problem may lie.
"java.lang.RuntimeException: Programmer's assertion in getNextStepPos:
unknown stepType: -1"
Cheers
Simon
