Today I ran into a pesky little issue when trying to query documents from sharepoint. In a previous example I talked about how to query documents from sharepoint, but what I did not know at the time is that if you have a field name that has a whitespace, you have to do some extra work.

If you have a field named ‘FooField’ all is good, however if you have a field named ‘Foo Field’ (notice the whitespace) you will get the following exception.
{System.Web.Services.Protocols.SoapException: Server was unable to process request. ---> One or more field types are not installed properly. Go to the list settings page to delete these fields. ---> One or more field types are not installed properly. Go to the list settings page to delete these fields.

To resolve this issue replace the whitespace with _x0020_ so the new field name would be ‘Foo_x0020_Field’.

Hope this helps someone.

Till next time
