I have been having some problems when trying to run certain services that take strings as input parameters. After investigation it turns out that there is an non display character being added to the end of the string so services are failing. In the example below (GQ201) I have a string a property on one of my things. I wrote a service to output this property for all implementing things & I put single quotation marks around the output, If you look closely you can see there is an extra character at the end of the string which presumably is some kind of control character that doesn't display. Even when I change this property manually via the composer it still seems to include this extra non displayable character.
Has anyone else come across this problem before, or does anyone have any ideas as to what is happening?
