Re: WSDL2RPG : Empty tag for decimal variables
The problem you have is a common problem with RPG because RPG does not
really support NULL values.
Leaving an XML element empty is one option to specify a NULL value in an
XML document. But since RPG does not support NULL values, WSDL2RPG does not
have a chance to properly recognize NULL values. For strings you may say
that a string value with length=0 is equal to NULL. Although that is not
really true it should work in most cases. Fine.
But for all other field types it is not that easy to define a substitution
value for NULL. For example you may say that for numeric fields the
substitute for NULL is 0. But is that really a good idea? I do not think
so. But what other value should we consider to be equal to NULL? *LOVAL or
*HIVAL? Bad.
I wished RPG had true NULL support. All you can do now is to say: "For me,
0 is equal to NULL" and then modify the generated stub accordingly.
I have been thinking about how to support NULL values since the day
WSDL2RPG was born. If it wasn't that ugly I would add a NULL indicator
field for each nillable field. If the NULL indicator is TRUE the field
would be treated as NULL regardless of its actual value. Honestly I do not
like that solution because you always have to set two fields for one value,
for example:
request.myNillableField.value = 123;
request.myNillableField.isNull = *OFF;
Or in case of a NULL value:
request.myNillableField.isNull = *ON;
Any other ideas how to solve that problem?
