How do I use an IF statement in a loop with StringTemplate

Question

This displays nothing:

$Articles:{ $if(i!=1)$ display in between articles $endif$ $it.Text
}

This displays as expected

$Articles:{ display in between articles $it.Text
}

Any ideas on how to get this working?

you need to compute all expressions and push into the template. You are clearly filtering, which shoul be done in the model not the view. Please see:

here, it says that $if tests for the presence of an attribute or evaluates a boolean expr. The only operator allowed is !(NOT),
so maybe you can define a boolean variable = (i!=1) and use it in the $if statement.

yeah I saw that, don't know how I can create a boolean value within a loop as a global one would be no use to me. The i value represents the current iteration. – Oct 15 '09 at 14:31
