Jet template for a new file not generated [message #548571]

Hello,

I trying to switch from EMF 2.0.1 to 2.5.0.

My problem is that I generate additional classes from my model and it does not work anymore.

For example:
Class.javajet (overrides standard template to generate {CLASS}.java) - this one works fine, generates with my template.
ClassProxy.javajet (this should generate a {CLASS}Proxy.java file) - this one is not generated, not even present in .JETEmitters src.

Dynamic templates and Force Overwrite are enabled.
I even tried to copy Class.javajet to ClassProxy.javajet and change class attribute in jet directive but with no success.

What do I miss ?
Thanks in advance,
Kate

this reality sucks

Better late than never! Given 2.6 is the latest release, that would
seem better...

We've never had such a template. So that's one of your own... Are the
other ones showing up there?

Do you see any errors in the Error log that might provide a clue?

How would a template EMF doesn't know about end up getting used?

I'll definitely give it a try when I get back from my vacation..

I have two own javajet templates and neither one of them shows up there. But isn't that the result of some incompatible changes in jet template format between 2.0.1 and 2.5.0 (like passing an array of Object instead of single object as script parameters) ? However no jet compilation errors were reported.
Nevertheless for a good start of migration I copied Class.javajet template into my templates/model directory and modified it a bit just to see if EMF will use it and it did. Modified Class.javajet template was used for generation - fine.
After that I copied Class.javajet into ClassProxy.javajet (and changed 'class' attribute to ClassProxy inside jet directive) - but as result ClassProxy_.java is missing in .JETEmmiters src. It seems that for some reason my dummy ClassProxy.javajet template is ignored.

> Do you see any errors in the Error log that might provide a clue?
no, didn't find anything related to this

> How would a template EMF doesn't know about end up getting used?
hm I don't get it

Kate,

Dynamic templates are only useful for overriding/specializing what's in
the default templates. Any new/other templates you add, simply won't
end up being used by EMF. So don't understand how ClassProxy.javajet
will be used. In fact, I think the dynamic templates are compiled on
demand so only the ones that EMF actually uses (tries to apply) will get
dynamically compiled. That's why I'm wondering how you use such
templates. We have an Example that shows how to extend the generator to
apply additional templates to produce additional artifacts...

Okay, that pretty much explains everything. I must have missed that info. I guess the migration won't be that easy then Sad

Thanks for quick answer
