Hi!
No, please don't convert the QdabraRules secondary data source to UDC. Patrick was referring to any other data connections in the form.
I would first suggest displaying the Error, Success and Result nodes on the canvas, temporarily, so that we can see if anything is happening when you call the command.
I would then suggest checking the Postback settings on the controls that call qRules. These need to be set to Always.
Finally, if the above doesn't work, try setting the form back to Domain trust (and make sure the site is added properly to your IE zone settings). The command CAN run in forms that are not full trust by using the dsnamews parameter. This is an undocumented option in qRules, but we should be blogging about it soon. The command will look like this:
SaveToSharePoint /url=http://servername/Documents/ /xpath=/my:myFields/my:Files/my:File /dsnamews=Upload
Upload is going to be a receive type data connection to the Copy web
service in SharePoint (http://servername/_vti_bin/Copy.asmx?WSDL) with
all blank parameters (in the data connection wizard). I'm attaching a
screenshot.
Hope this helps!
