This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
I have a servlet which is invoked by the doGet() method. This servlet has a FORM which has few fields. One of the field has a hyperlink which makes a window.open() call for Onclick. This pop-up allows a user to search for some value. The result of the search is displayed in a SELECT box. Based on the value selected in this SELECT box, the field in the servlet that called this pop-up gets populated. After this is done, I close this pop-up & click on the proceed button of the FORM (using POST) which takes us to another servlet. Then when I click on the back button, the fields on the form which were populated are gone.
I have made the following analysis: (i) On clicking the back button, a request is sent to the server. (ii) It works on FireFox & not on IE (iii) If I do not use the hyperlink to bring the pop-up, and then I click on proceed and then back, the fields do not vanish. (iv) I tried using http://www.ggogle.com to the call on window.open(). Does not help (v) The very action of using pop-up by clicking on it causes this problem
Any help or tips in this regard would be really appreciated.
Naresh, I am not sure about Mahesh's problem, but what you said about IE sessions is not true. On Windows XP each new IE instance is started in the context of a new process, and does not share non-persistent sessions with other IE windows. However, if you do a Ctrl-N or File>>New>>Window and spawn another window in the context of the current process, the sessions are shared between the two windows. As Mahesh's popup is spawned by the current window, it should share the session with the parent window. The issue of the session not being shared between IE processes is a matter of process isolation and it behaves differently between OS versions. This behaviour will not be seen in the Win9x family.
