Page navigation buttons not working properly

Question

Hi,
I am having a multilingual Java Application (e.g. English, Japanese, French...).  In this application there are reports which display the data using locale parameter (like en_US, ja_JP etc.) to display the data in selected language.
The problem comes up when I see Japanese reports on English operating system machine and vice versa.
When I click any button of page navigation it changes the page number but does not load and display the page accordingly.
It's like when I run the report it displays the first page, then clicking on Next button brings 2 in navigation field but the report  would still show first page, same happens for 3, 4.... all pages. 
The other navigation buttons also do not work, they change the page number but display only the first page.
This problem does not occur when I see Japanese reports on Japanese OS machine and English reports on English OS machine.
However my clients need the first case, Japanese reports should work on English OS machine also.
Please advise urgenly.

Hi,
I resolved the above issue by removing the call to method setProductLocale in jsp file (which was really unnecessary in code as product locale is meant to set languange for crystal report design environment ).
Actually the problem was I had set locale at two place
                1. using setLocale method of ReportClientDocument object) after the initialization of report client document object
                2. using setProductLocale method of CrystalReportViewer object after the initialization of Crystal Report Viewer  object
After commenting out code for setProductLocale, reports in all languages and all their functionalities started working 100% perfectly.
Thanks.
