what is the difference between mainwindow n final window?
Answer Posted / senthil
There can be only one main window.
There can be one or more final windows.
Final windows are processed only after all the nodes in the tree have been processed.
You may want to display or query values on the first page that are determined only during processing.
For example, you may want to name the grand total in the letter text of an invoice. However, this amount is determined only after listing all individual items. Or you may want to query on the first page within a condition the total number of pages, which the system calculates only after processing all pages.
In such a case, you use the final window.
