JasperReport conector error

I used BOS 6.3.3. I have a error with the conector of JasperReport, i fill the fields in the wizards of the conector, but when i press the test button, BOS show me the following message:

Input parameter ‘jrxmlDocument’ using a unreacheable expression.

I follow all the steps in the official site for configure Jasper and Bonita:

http://documentation.bonitasoft.com/jasper-50-0

but i have the same error i dont know why. Please help me with this.

Are you sure to have followed these steps?

  • define a new document (called for example jrxmlDocument)
  • initialize it importing there the .jrxml file
  • in the jasper connector wizard bind as input parameter the jrxmlDocument

Hope it helps.
Cheers
