problem passing the ressource bundle parameter from the master report to the subreport

i have a problem passing the ressource bundle parameter from the master report to the subreport : 

here the issue :

i used parameters.put(JRParameter.REPORT_RESOURCE_BUNDLE, resourceBundle); to put the ressoyrce into the main report

in the master report template i added a subreport element and put the same parameter as a subreportparameter 

but as an output the ressource work only for the master report i even changed the name of the parameter to "MASTER_REPORT_RESOURCE_BUNDLE" to avoid conflict with the default parametr.

i in desperate need for help .

Thanks in advance
