Hello and Thanks for your reply. I think i have to tell some more details.
I'm working for an university and i got the task to program some administrator-frontend granting and withdraw roles to our 40.000 user as an infopath-formular.
It seemes for me that i can only use prepared tables and views (or stored procedures) to an infopath secondary-connection. I tried to use some normal views for my formular but infopath got very slow with rows from 6000 testuser. Thats why i tryied to personalize the SQL-Querys depending on some other fields in the formular.
With xdExtension i got the possibility to run one procedure for every secondary-data-connection and configure in these procedure the where-clause depending on the values of other formularfields.
All works fine for the formular hosting in infopath. if i now activate "browser-enabled Forms" the design-detective detects no errors. Due to the fact that i used code i cant publish my formular direct from infopath. The publishing process need the sharepoint central-administration to publish the formular. For this publishing-process the formular have to pass a "verify"-step bevor the upload takes place.
In this verify-step i got the error "Fehler beim Analysieren des folgenden Ausdrucks. Die Ursache ist ein Syntaxfehler oder die Verwendung eines nicht definierten Namespacepräfixes oder einer nicht unterstützten Funktion: xdExtension:OrgInfo_for_Account_abfragen() and false.". in english its something like "error on analysing the following expression. the errorcause could be a syntaxerror, a not defined namespaceprefix or a not provided function: xdExtension:OrgInfo_for_Account_abfragen() and false." The origin of this error is manifest.xsf.
Like you posted the xdextension namespace is automaticaly created in the manifest.xsf.
Greetings and thanks for some ideas.
Jens
