Attribute named 'function' in ETL [message #537211]

Hi,
If a metamodel class has an attribute named 'function' then it appears
to cause problems within an ETL rule:

(1)rule MyRule
(2) transform inItem : Source!InputModelElement
(3) to outItem : Target!OutputModelElement {
(4) outItem.name := inItem.function;
(5) outItem.number := inItem.number.asInteger();
(6)}

Line 4 won't parse as it stands, 'function' appears to be a reserved
word in ETL (EOL?). Can I escape the attribute name in some way?

Regards
Chris

Hi Chris,

You can use backticks to escape reserved words. E.g.

outItem.name := inItem.`function`;

Cheers,
Dimitris
