jdk 1.6.0_31 as well. We should test with combinations of Kepler/Luna and Acceleo 3.4/3.5. It might me a change/regression introduced in Acceleo 3.5 (if 3.4 works), or related to https://bugs.eclipse.org/bugs/show_bug.cgi?id=419205 which makes parts of Acceleo (all versions) not work on Luna. The bug is marked fixed, but the fix is just a workaround to tell users not to use the mode that does not work. Basically, the "magic" that Acceleo does to dynamically load Java code from the workspace without launching a separate runtime does not work anymore with Luna. It could be the cause for the CNFE we see, as the service classes are in the workspace only. Created attachment 245728 [details] Result with Sirius 1.0.x nightly on Kepler with Acceleo 3.4 I have just tried with . eclipse-standard-kepler-SR2-Java8-win32, . Sirius 1.0.x nightly . http://download.eclipse.org/sirius/updates/nightly/1.0.x/kepler . Acceleo 3.4 is installed. The service call from an Acceleo3 expression are wrking fine (see the attached screenshot) I have updated the environment used in the previous comment to have Kepler/Sirius 1.0.x nightly / Acceleo 3.5 It fails to evaluate the service in live editing mode. Hi Acceleo guys,
as said by Pierre-Charles:

But it does not work anymore with Accleo 3.5 on Kepler too.
Could you help us to detect what is broken ?
Dynamically loading plugins from the workspace no longer works since Luna as the platform removed the (internal) APIs that allowed us to do so. |
Created attachment 245576 [details] Sample project with java service Steps to reproduce: . Unzip the attached sample project in your workspace. Do not deploy it. . Open the aird file and its contained diagram (model folder) . One of the container is named "invalid", the label is rendered from the service in RenderService.java -> KO . Note that the completion proposes the service.
