Dear all,
I need to perform a boolean comparison in an if block. Something like:
[if (class.getTaggedValue(class, 'Stereotype', 'initRandom') == 'TRUE')]
According to the 2.6 reference manual, the following operators should be available (page 9):
Quote:== (equal), != (different), < (less than), <= (less or equal than), > (greater than >= (greater than or equal), || (logical or), && (logical and) and ! (negation)
But whenever I use them I get this error: "=" unexpected token(s). Am I doing something wrong? Or have the boolean operators changed since version 2.6?
Thank you,
Luís

Hi
I've no idea about 2.x, but Acceleo 3.x complies with the OMG MOFM2T
specification that is based on OCL, for which the relational operators are
=, <>, <=, <, >, >=
and the literals are
true, false
