Problem with providing variable to template [message #839869]

I am trying to add variables (input parameters) to my EGLTemplate:

EglFileGeneratingTemplateFactory factory = new EglFileGeneratingTemplateFactory();
factory.getContext().getFrameStack().put(new Variable("outputLocation", outputLocation, EolPrimitiveType.String));
EglTemplate template = factory.load(getEntry());
template.process();

When I check the type of 'outputLocation' in my egl file (grabbed from getEntry() earlier), its type is unset. This code returns 'Type: ' instead of 'Type: String' (or something similar):

("Type: " + outputLocation.type()).println();

So, obviously my next statement

t.generate(outputLocation);

goes wrong as it expects a String for the location parameter. (Changing it to

t.generate(outputLocation + "");

'solves' my problem)

Is this a bug that I should report, or am I doing something wrong here?

Hi Maarten,

Thanks for doing this. To speed things up could you perhaps put together a minimal example I can use to reproduce this?

Cheers,
Dimitris

Hi,

When I created my minimal example it did not fail... Wink

It was my error: outputLocation was an URI instance. So, adding the +"" resulting in a conversion to String.
So by converting it to a string when I created the variable fixed my problem:

factory.getContext().getFrameStack().put(new Variable("outputLocation", outputLocation.toString(), EolPrimitiveType.String));

Thanks for your time.
Cheers,
Maarten

PS Only thing is, that this message could be make clearer:

Method 'generate' not found for: org.eclipse.epsilon.egl.EglFileGeneratingTemplate@2d7cec96 (Driver.egl@6:7)

Maybe by adding the used method parameter types, so the user sees why the method is not found..? (In this case I would have easily seen that I was accidentally using the URI object)
