Populate list with all organizations in the same customer account

[javier.varga...@gmail.com]

Hello!
I want to populate a list widget with all organizations in the same customer account, then I want to populate another list widget with the roles for the selected organization on previous list widget and then I want to populate a multiselect list widget with the user of the selected role for the selected organization.
How can I get the list of all organizations in the same customer account?
And then how can I get the roles for this organization and it users?

Thanks!

Finally I did it with a new connector and the RSS Service.

Thanks!
