iview getting refresh continously

Hi,

We have an custom ABAP WDP application, integrated it in the Portal.

it runs fine when checked from the backend(SICF - test service) and also thru the URL.

But when we check for the same in the Portal iview - preview or from the service added in the Homepage .. the page just gets refreshed n refreshed .. nothing happens ..

Can some one help me with this

Regards,

NR
