Most effective way to dynamically load a form

Ethan,

If page A wants to tell page B to load form "foobar", I would simply
put "foobar" on the URL which loads page B, whether as part of the
path or as a URL parameter. Then you can, in XForms, load the proper
XML document from the database, using e.g.
xxforms:get-request-parameter().

If you want to use JavaScript, then try the setValue() method from our JS API:

Thanks!

It works.  I found this blog article that illustrates the issue very nicely

What do you mean by "opening 'id'.xml"? Are you loading that file into
an instance? Or loading that file in the browser (a sort of
redirection)?

So you want the "form" to load in the browser the XML from eXist right
away. So the form wouldn't really be displayed, it would right away do
a redirect to the XML. You can do this by having:

<xforms:load ev:event="xforms-model-construct-done"
    resource="/exist/rest/db/projectname/{xxforms:get-request-parameter('id')}"/>

Orbeon Forms is smart enough to detect that, and will issue a redirect
to the browser, which will go to the page you mentioned right away.

I see; so the XML would go into an instance of the form. Maybe you can
try having a submission:

<xforms:submission  id="initial-load"

   resource="/exist/rest/db/projectname/{xxforms:get-request-parameter('id')}"

   serialization="none" replace="instance" instance="your-instance"/>

And you run that submission on xforms-model-construct-done:

<xforms:send ev:event="xforms-model-construct-done" submission="initial-load"/>

(Note that because the submission makes a reference to
xxforms:get-request-parameter(), you can only use it when the page is
produced by the XForms server. You won't be able to run it later. I
you need to, you'll have to store the value of that request parameter
in an instance.)
