Im trying to update text field from dialog box .The text field is in the parent component. But its not happening . If i give the id of text field in the update of command button
Finally, i have got the solution . The exception i have encountered is because of the form tag . The ajax event fired from the dialog is not able to find the component outside the form .In this case use: :#{p:component('componentId')}
Here it will search the id not only within the form but outside of it.
