View with external URLs

I created a new component and it has a view that contains links to external URLs. I made the component as a work center and works fine. The external URLs always open in a new window. I would like to open in the same CRM_UI_Frame window.

i use <thtmlb:link id="google" text="google" reference="http://www.google.com" target="_self"></thtmlb:link>

I tried target="_parent" also.

Any help appreciated.
