Hi,
I'm trying to add a rule to a textbox that gets data from my secondary datasource but I keep getting this error:

Reference to undeclared namespace prefix: 'tns'.

I have my namespaces declared like so :

XDocument.DOM.setProperty "SelectionNamespaces", "xmlns:s0=""http://xxx/CDS/wsSAPLookup"" xmlns:tns=""http://xxx/CDS/wsSAPLookup"" xmlns:dfs=""http://schemas.microsoft.com/office/infopath/2003/dataFormSolution"" xmlns:my=""http://schemas.microsoft.com/office/infopath/2003/myXSD/2006-01-08T22:33:58"""


What's puzzling is I am already using this second data source to put values in a drop list and I'm not getting any errors with that.

Any ideas ?

Hi,

Are you sure that you don't have a / at the end of the namespace?

like this:
xmlns:tns=""http://xxx/CDS/wsSAPLookup/""

One times I have forget and that didn't work anymore :)
