R12 html forms timed out and re-authentication does not bring you back to the form

Hi,

I've upgrade from 11.5.10.2 to 12.1.3. My context file has s_oc4j_sesstimeout = 30 and s_sesstimeout = 18000000 (which is also 30 minutes). The user is presented with a login pop-up box so she types in her user and password information and click ok. It brings her back to the main login page http://hostname:port/OA_HTML/AppsLogin instead of the form which she left to timeout. Is this expected behavior? In 11i, you were able to re-authenticate after form timed out and get back to the form. In R12, Should after successful re-authentication bring her back to her timed-out form with no data loss?
