Communication between separate windows

Question

Hello,
I am a JSF newbie and i have the following problem.
I have one JSF-Site where the user can enter a value in an input_text field. I want to open another page in a new, separate window when the value of this field has changed. This is possible by using the onchange-attibute with the javascript: "this.form.submit(); window.open (...)"
In the new window, there?s a table with the possibly results of a selection. Each row has one button to select the row. In the onclick-attribute i tried to work with the javascript: "this.form.submit(); window.opener.location='<Adress from the first JSF-Page>';window.close();"
The data for the two pages are saved in a session bean.
The problem is, sometimes it works, mostly not. The window is closing correctly, but the first window was not updated.
Is there another way to work with separat windows? Can i manage the windows within a bean?
Thanks for your help.

I assume this kind of behaviour is due to the life cycle of the submitted page. The values in your new page have not been persisted yet in the bean while the first page is opening, so the render gets the old values.
Is it not possible to pass the selected value from the new page through parameters in the URL of the first page instead of getting them from the bean?
Second solution, in JSF 1.2, you can use the attribute beforePhase related to <f:view> in order to wait for the persisting of the new values in the bean. The load of the first page is conditionned to a flag set after the persisting in the bean.
