I’m trying to open a window in my web, that doesn’t have any tools, like showmodaldialog, and I get some values from it, which is requested by the same window.
I made it, but don’t work, and I don’t know why? The modaldialog is opening, but it is opening in a new window, not the same that was required. After some speculation I tried with <base target="_self" /> in head tag, trying to afect the page desired, but didn’t worked anyway.

Could someone give some help?
