$P{REPORT_SCRIPTLET} sometimes/always(?) cannot be called twice within an expression

I wanted to include a subreport which is fine as long as one does not reference/call the scriptlet via the $P{REPORT_SCRIPTLET} multiple times:

<subreport>
  ...
  <subreportExpression>
     /* "/myrep.jrxml" */                       /* runs fine */

     /* $P{REPORT_SCRIPTLET}.getMyRepPath() */  /* returns the above and runs fine */

     /* the report runs to the fill phase and may or may not (both experienced) 
      * after some time return and say, e.g. that the file has not been found 
      */
     $P{REPORT_SCRIPTLET}.dbg( "subreport: ", $P{REPORT_SCRIPTLET}.getMyRepPath() )
  </subreportExpression>
</subreport>

It is based on the Jasper Utils EnvScriptlet in case it gives a clue about the cause.

Solution

  • calling the static method directly in the 2nd invocation like this however works fine:

    <subreport>
  ...
  <subreportExpression>
     $P{REPORT_SCRIPTLET}.dbg( "subreport: ", EnvScriptlet.getMyRepPath() )
  </subreportExpression>
</subreport>
