Hi, I have 2 questions:

1)how can I truncate a string in DSP or template?

2)I have 5 elements in the document. I want to check if document type is null or not in DSP. I used %ifvar documentName -isnull% or %ifvar documentName -notempty% but in some cases, it is giving the result
and in some cases, giving opposite result.

Thanks

Truncating via javascript works for me in DSP’s:
StringA = StringB(Start_Pos, End_pos);

Field presence checking that i have used:
%ifvar operation exists%

Truncating via javascript works for me in DSP’s:
StringA = StringB.substring(Start_Pos, End_pos);

On the truncation issue: you could also just write a wrapper service around the service you were wishing to invoke which performed the truncation.

There’s also the (messy) option to invoke a service in your DSP for each thing you want to truncate, though that would get very messy, very quickly.

My option would be to create a wrapper service that was just for the UI invocation of your service. Should simplify your DSP too.
