soma Apex code generation from WSDL error - variables using reserved word names
I created a simple webservice in C# for the purposes of processing some data to send emails. One of the parameters for a function of my webservice was called "from". I generated the WSDL for this webservice (and removed all SOAP 1.2 tags), then went to the sandbox to generate the Apex code from the WSDL. The code was generated, but there was an error (see the generated Apex class following this discussion). It took me quite a while to figure out what the problem was. Examining the Apex code revealed nothing, but then I read another post in this forum where someone noted that he/she was able to generate Apex code with reserved words as variable names, e.g. public String return; and this caused a problem. I suppose 'from' is one of those keywords in Apex, so I renamed the field in my code, rewrote the WSDL, then regenerated the Apex code from the WSDL and all was well. The error and the code that generated the error follows:

The following generated class(es) have compilation errors:

"From" is a reserved keyword and can not be used as a variable anywhere in apex. Renaming it should fix the problem. Maybe "source" instead? A list of reserved keywords can be located on page 171 of the reference guide.
