OIF with multiple GUIBBs- Save data

Hi Experts,

I have come up with a requirement which is very common I am sure but I juts need some help.

My requirement is -  I will have a OIF screen and inside that I will have a tabbed UIBB or lets say multiple GUIBBS. IN each GUIBB there are a set of fields. The user will open the application and fill out those fields and will be able to save them.

Now, while saving those values will go into different tables so wherever I write the logic for save I will need the data entered in all the GUIBBs.

Lets say I use same feeder for all the GUIBBs. Then how is it going to be possible to get all the data for all the UIBBs..

Many thanks in advance.
