when you click on Hyper link in CMS Portlet Window, the target is going to home page instead of target window. pls do this needful
Yes, that is the way it works. If you want to display an HTML page from CMS, then the page is shown in the CMS portlet window, which is on the home page.
As far as I know, the only way to get an HTML page to display in another portlet window is to make a copy of the CMS portlet window class and modify it such that any HTML pages requested from that window get sent back to that window.
