Hi
I have a problem with definition of Set or variable.
In the following code:
---------------------
[template public generateElement(d : DangerClass){ a:Set(AgentClass)=Set{};}]
[comment @main/]
[file (d.name + '.java', false, 'UTF-8')]
[for (h:Hazard | d.ownedHazard)]
[for (e:Element | h.entity) ]
[if (e.oclIsKindOf(AgentClass)) {a->including(e);}][/if]
[/for]
[/for]
[/file]
[/template]
---------------
the error ". expected instead of {" is shown.(Line 6)
If I write "[for (e:Element | h.entity) {a->including(e);}]" the error "variable a->including(e); is not valid" will be displayed.
I want to define a set ("a" as Set(AgentClass)) that "a" includes agents and I don`t want to print something.But I want to store agents in a set.
Can anyone help me?
Thanks

Hi

You might get a much faster response if you provided an executable repro.

The ". expected instead of {" is very accurate. There is no syntax that
allows a { in an [/if clause.

You appear to have completely misunderstood the purpose of Acceleo. It
is a declarative Model to Text language.

You seem to want an imperative model query language. Try
Java/Xtend/QVTo/ATL/...
