Hi,

I try to migrate a projet from Acceleo 2.6 to Acceleo 3.1 and i have a problem with

requests.

in my acceleo 2 project i have this code ( ownedParameter[direction=="in"])

<%for (ownedOperation){%>
    <% common_signature%>(<%ownedParameter[direction=="in"].nSort().common_parameter.sep(", ")%>) throws GenericException{

then with this code, request filter only on parameter with direction = "in" that is good.

on acceleo 3 i write this :

[for (ownedOperation)]
[javadoc_method()/]
    [common_signature()/]([ownedParameter->select(direction = 'in')->sortedBy(toString()).common_parameter()->sep(', ')/]) throws GenericException{

then ownedParameter->select(direction = 'in') return always nothing.

Could you help me to find my mistakes

thanks

Hi,

You should change your code for something like this:

ownedParameter->select(direction = DirectionKind::IN)

Since I'm pretty sure that the direction in your metamodel is an enumeration and enumerations are manipulated differently in Acceleo 3 (MyObject.myEnumValue = MyEumeration::myEnumerationLiteral).

For more information, you can have a look at the Acceleo user guide which contains videos and tons of screenshots, the best practices guide (where you can find lot of information to create a good generator and where we are often adding new recommendations). the FAQ or even an open source example of UML to Java generator that you can fork as you want.

Regards,
