In PowerBuilder versions 10.5 and later, you cannot use system types as variable names in Web service proxies.
If a PowerBuilder system type is used as a variable name, the Web
Service Proxy wizard renames the variable by applying the prefix
ws_. If you are migrating Web service applications
from PowerBuilder 10.2 or earlier, and regenerating the Web service
proxies in PowerBuilder 10.5 or later, you may need to modify your code
to reflect the change in variable names.
PowerBuilder system types include not only the objects and
controls listed on the System tab page in the PowerBuilder Browser, but
also the enumerated types listed on the Enumerated page in the Browser,
such as band, button, encoding, location, and weekday. For example, if
you build a Web service from a PowerBuilder custom class user object,
and one of its functions has a string argument named
location, in the proxy generated for that Web
service, the argument is changed to
ws_location.
