Just some notes relating to error codes received during Sharepoint integration using the UpdateListItems method of the lists.asmx service.
A value in the update for a column exceeded the maximum column size.
<ErrorCode xmlns="http://schemas.microsoft.com/sharepoint/soap/">Invalid text value
A text field contains invalid data. Please check the value and try again.</ErrorText>
A column to be updated was passed in that did not exist.
<ErrorCode xmlns="http://schemas.microsoft.com/sharepoint/soap/">One or more field types are not installed properly. Go to the list settings page to delete these fields.</ErrorText>
</Result>
The field being updated was a lookup field that allows multiple values and the value passed in contained a trailing ";". A trailing semi-colon only seems to be an issue when it is the first item in the list.
<!-- <Field Name="VehicleFeatures">1,#Cassette Radio;</Field> -->
<ErrorCode xmlns="http://schemas.microsoft.com/sharepoint/soap/">Bad parameter passed to Web Server Extensions. Check the information you entered and try again.</ErrorText>
</Result>
