Hello there,
i have a (main)template which expects 2 arguments besides the EObject it generates for.
Before the update that came with Indigo, i could simply add these arguments in the run configuration under "properties" (one argument per line). This does not work with the new version.
I understand the procedure for this has been changed, but i dont understand how this works. Obviously, one argument per line in the "properties files" tab does not work, but when i add the workspace path of a file that contains the arguments, it does not work either.
I know i can pass these arguments by calling the generate() method, but as of now i would like to know how i can achieve what i have done with the previous version 
Also, i got an annoying bug:
When starting eclipse and launching my plugin-project (meaning the acceleo project "lives" in the second instance of eclipse), acceleo does not recognize the template's metamodel, although it is correct. I have to change the name of the metamodel first and then rename it to its correct name again for acceleo to recognize the metamodel.
Something i could try about this?
Thanks for your help, really nice support here

Hi,
The Run Configuration was buggy with this feature since it was used for two different features at the same time. It was use to enter the path of properties files and to enter arguments that would be used during the generation. Now, the configuration has been simplified and you can enter in the run configuration the path of properties files just like in the "getProperties()" method.
If you want to get the old behavior back, you can launch it with the Java Application mode and change the main method of the generated Java class to from this:
public static void main(String[] args) {
try {
if (args.length < 2) {
System.out.println("Arguments not valid : {model, folder}.");
} else {
URI modelURI = URI.createFileURI(args[0]);
File folder = new File(args[1]);
List<String> arguments = new ArrayList<String>();
Workflow generator = new Workflow(modelURI, folder, arguments);
for (int i = 2; i < args.length; i++) {
generator.addPropertiesFile(args[i]);
}
generator.doGenerate(new BasicMonitor());
}
} catch (IOException e) {
e.printStackTrace();
}
}
to that:
public static void main(String[] args) {
try {
if (args.length < 2) {
System.out.println("Arguments not valid : {model, folder}.");
} else {
URI modelURI = URI.createFileURI(args[0]);
File folder = new File(args[1]);
List<String> arguments = new ArrayList<String>();
for (int i = 2; i < args.length; i++) {
arguments .add(args[i]);
}
Workflow generator = new Workflow(modelURI, folder, arguments);
generator.doGenerate(new BasicMonitor());
}
} catch (IOException e) {
e.printStackTrace();
}
}
After all, the Run Configuration of Acceleo is just the Java one with a new look an few more widgets, you type anything you want in this configuration and you can use it as you want later.
As for your bug, do you have the "automatic build activated"? (Project -> Build Automatically).

Hi Stephane
I don't understand why a minor version change has removed this user
interface facility.
Surely arguments are much more useful than properties, which if required
can be passed as -properties=... ? the converse doesn't work.
And the Acceleo documentation in the RunConfigurations section shows a
picture of an Acceleo Tab with
a properties panel and a description of how to add arguments one per line.
[The comments in
List<String> arguments = new ArrayList<String>();
/*
* Add in this list all the arguments used by the
starting point of the generation
* If your main template is called on an element of
your model and a String, you can
* add in "arguments" this "String" attribute.
*/
GenerateJava generator = new GenerateJava(modelURI,
folder, arguments);
make no sense to me. Surely the args/arguments need mutual filtering,
and how is this code protected from regeneration?]
Please put the command line arguments facility back.
Regards
Ed Willink
