How can multiple users work on same project / same form at a time?
Something like a repository.
In our project there are multiple sections & work is divided on these sections. We tried to save the same form from different systems but form saves only recent data (recently saved form).
Is there a method to club or merge code?
After researching I found an alternative.
We are team of 4 & we spitted our work based on the Sections. Make sure that each developer should have Unique Section.
Go through the Orbeon Source & Collapse XML Tags shown in Image.
after doing this your code should look like above.
Point #1: Copy your other sections here
Point #2: Copy your Binding Code.
Point #3: Copy your Services & Actions
Point #4: Copy your form sections.
This is how we merged 4 different application. Few things to be checked
All the best! Happy Coding :)
