Dieter,
I would like to hear Alex's confirmation, but I suspect that this may be due to the way the XForms instances are encoded in URLs. Passing a parameter named id=123 may be mistakenly interpreted by the XForms engine, which modifies your instance.
If this is the case, it is problematic and we will have to fix it. In principle, if you just do a get on the /admin/clubs/club?id=123 anyway, the XForms engine should not try to modify the instance. It should only try to reconstitute an instance when a form is submitted.
In the meanwhile, can you try to name your parameter $id to see if that changes the result?

Hi, in my current project I'm using an XForms instance which is filled with values from an SQL database.
page-flow.xml: -------------- <page path-info="/admin/clubs/club" xforms="/resources/admin/clubs/club/form.xpl" .../>
form.xpl: --------- <p:processor name="oxf:sql"> ... <sql:query> SELECT * FROM clubs </sql:query> <sql:results> <xf:model> <xf:instance> ...
Everything just works fine, as long as I do a static SQL query. But I want to pass a request parameter like this: "/admin/clubs/club?id=123". But this fails: a certain entry in the form (namely "action") is missing (but it should be there!). For the request input I prepended a generator like this:
<p:processor name="oxf:request"> <p:input name="config"> <config> <include>/request/parameters</include> </config> </p:input> <p:output name="data" id="request"/> </p:processor>
<p:processor name="oxf:sql"> <p:input name="data" href="#request"/> ... <sql:query> SELECT * FROM clubs WHERE id = <sql:param type="xs:string" select="/request/parameters/parameter[name = 'id']/value"/> ...
That looks good to me. Why does it fail? Can anybody help?
Thanks ~Dieter
