"Select an entry" link in edit window of Multi-page Portlet not working..

[VRaj_90]

Hello Cognos Folks,

I am facing one trivial problem in creating portal page in cognos for my client.
When I create a page using portlets for ex: multi-page, then in its edit properties box,
it seemed that i can't access "Select an entry" link to provide folder path to the portlet.

I have checked all possibilities like
[1] Checking whether the Portlet is locked or not in Cognos Administration.  (Well it is not locked in this case)
[2] Checking whether the access permissions of that page are appropriate. (all access are granted to that page)

If I go to the path like:
Cognos Administration--> Configuration tab--> Portlets tab--> multi-page--> Actions--> view or modify this portlet--> edit button..
Here the link is working fine, in fact all links of all portlets are working fine if I followed the path stated above for all portlets.

From my RnD work, though I am not sure about this, but I found something like maybe,
the Javascript of that link is protected or restricted may be, to control modification of already created pages in the portal.

A solution is needed as soon as possible from you Guru's, eagerly waiting for your replies...
