Setting role in form

I'm using request headers to set the role of the person entering a form, so someone opening a request uses the URL 'xxxx/app/form/new?orbeon-role=Requestor.

That successfully sets $fr-roles so that I can access their role inside the form and show them the parts of the form I want them to see.

There are some conditions under which I might want to allow someone to change their role - specifically, for someone with an 'Approver' role, most of a form will be read-only. In order to allow them to create a form, I want them to be able to become a requestor. I don't want them to have two roles at once, because then the 'read-only' and 'visibility' mechanism breaks down; if someone is both Approver and Requestor, I can't make a form read-only for them.

I'm doing this by modifying the code for the 'new' button on the summary screen, so that when someone with the role of Approver wishes to create a request, they can click on the 'new' button. I added a '?orbeon-role=Requestor' to the URL that gets called when the new button is pressed. I can see that the URL is correct in the browser, but the role doesn't change, so I suspect that the request headers are read once in a session to provide a value for $fr-roles and not again until the user actually logs out and back in.

Can I set the fr-roles variable manually to achieve what I want, and if so, where do I need to do it to make it work ?

Hi James,

What version is this on? I can't remember of an orbeon-role request parameter that would be used to set that the user's current role is. I am searching through our latest code, and don't see any occurrence of orbeon-role (not to be confused with the Orbeon-Roles header).

Re: Setting role in form

Alex,

I found a different and more workable approach. This is no longer an issue.

Thanks,
James.
