Changes to application configuration not affecting the page

Hi,

I changed the application configuration RPM_ITEM_DETAILS_CFG and launched the WDA application, but the changes are not reflected. I can clearly see the configuration id in the end of WDA URL. I made changes to all the variants and tried changing button texts, tab headings etc. But none of the changes are reflected either in portal or in standalone WDA application.

Am I missing any thing?

Regards,

Ravikanth
