I have a web app that will basically have two types of web forms, a locator
form with a datagrid and a detail form.  The locator form will display a
list of objects such as customers etc.  The user will be able to either
click a button to create a new object, click a link to edit an existing
object or click delete to delete an object.  If adding a new record or
editing an existing I will display a detail form to fill in.  The user will
fill in the info and when done save the record and record to the locator
form.  I am torn between using javascript open to pop up the detail form and
then save will close it to return to the form below or to move to a new
browser window to display the detail form and then redirect after saving.
Which is the more accepted for data entry web sites and is more user
friendly?
