window.opener lost after redirect
<p>The situation is as follows:
I have a main window which opens a child window using window.open(). Then there are couple of forwards (it's Struts 1) because this is a multi-step wizard and the user can select multiple options in each step.</p>

<p>The problem is however that the window.opener is undefined in the last step of the wizard and I want to set a hidden filed in the parent page to some value(the page which actually created the window in which the wizard is happening). Window.opener is lost after going to the second step of the wizard.</p>

<p>Thanks for any suggestions.</p>
