Form runner not populating control values from DB

Hi,

I have an requirement where in,

I have a template  where on click on a particular control, brings data from database(Mysql) and populates the fields on

Template, then I should be able to generate PDF of template using PDF button on form runner.  

To achieve this,

#  I have designed a template(Form)  using form builder which have DataBaseService(pointing to jndi datasource)/Action defined for the form,

Template is having minimal three fields,

#  A button, on click of which database service is called

#  A SingleLineText control which is used to pass parameter for database service.

#  A SingleLineText control which is used to present the value returned from the database service.

On placing value in input control, the output control is not getting populated after

clicking the the button to invoke database service.

I am not getting error as well,

The below is snapshot of orbeon logs on doing above action.

Based on above logs can anyone point to the issue,

Would appreciate any help,
