Problem with custom popover for iPhone

[santosh_kumar]

Hi all, i have a problem with custom popover for iPhone. In fact popover is working fine but the location of popover is creating problems. When i clicked a textfield, popover should present from that point instead it is displaying from (0,0,-,-). one more thing is that i have various panels inside the page,each panel comprise various controls including textfield attached to the scrollview. My observation is popover is invisible if we set the frame that is beyond the display area of iPhone.

Is it the problem of scrolling page or panels inside the page? why it is not taking the right location when we triggered from -(BOOL)textFieldShouldBeginEditingUITextField *) textField method?
