Hi,
I tried to setup render and rendertester in different bundles, to archive project specific rendertesters.
In my case it's not working because the render needs the corresponding rendertester in the same bundle, same for rendertester.
I took a look to SWTRenderFactoryImpl.readBundle and saw that this is the actual behavior.
loadClass(configurationElement.getContributor().getName()...
Therefore I patched the renders.exsd to add a optional bundle name as string. Maybe there's a nicer way to archive that instead of a string. But this did the trick. Here's the modified readRender
private void readRenderer() {
final IExtensionPoint extensionPoint = Platform.getExtensionRegistry().getExtensionPoint(RENDER_EXTENSION);
for (final IExtension extension : extensionPoint.getExtensions()) {
for (final IConfigurationElement configurationElement : extension.getConfigurationElements()) {
try {
// PATCH START
String bundleName = configurationElement.getContributor().getName();
if (configurationElement.getAttribute("bundle") != null
&& !configurationElement.getAttribute("bundle").isEmpty()
&& Platform.getBundle(configurationElement.getAttribute("bundle")) != null) {
bundleName = configurationElement.getAttribute("bundle");
}
//ORIG:final Class<AbstractSWTRenderer<VElement>> renderer = loadClass(configurationElement.getContributor().getName(), configurationElement.getAttribute("renderer")); //$NON-NLS-1$
final Class<AbstractSWTRenderer<VElement>> renderer = loadClass(bundleName, configurationElement.getAttribute("renderer")); //$NON-NLS-1$
// PATCH END
final Set<ECPRendererTester> tester = new LinkedHashSet<ECPRendererTester>();
for (final IConfigurationElement testerExtension : configurationElement.getChildren()) {
if (TEST_DYNAMIC.equals(testerExtension.getName())) {
tester.add((ECPRendererTester) testerExtension.createExecutableExtension(RENDERER_TESTER));
} else if (TEST_STATIC.equals(testerExtension.getName())) {
final int priority = Integer.parseInt(testerExtension.getAttribute(TESTER_PRIORITY));
final String vElement = testerExtension.getAttribute(TESTER_VELEMENT);
final Class<? extends VElement> supportedEObject = loadClass(testerExtension.getContributor().getName(), vElement);
tester.add(new ECPStaticRendererTester(priority, supportedEObject));
}
}
rendererDescriptors.add(new ECPRendererDescription(renderer, tester));
} catch (final CoreException ex) {
ex.printStackTrace();
} catch (final ClassNotFoundException e) {
e.printStackTrace();
} catch (final InvalidRegistryObjectException e) {
e.printStackTrace();
}
}
}
}
Or is there a different way to archive that? When exactly do i use additionalRenders extension point?
Cheers
Philippe

Hi,
I see your issue. I acually wonder, why "createExecutableExtension" is
not used here. This would IMHO solve the problem.
Could you kindly report a BR for this and add me to CC?
Best regards

Hi,
thanks! "Additional Renderers" is a very specific concept to replace
renderers for a certain GridCell. It is not really officially supported.
For your use cases, I believe you will just need the regular renderer
extension, not the "additional renderer".
About the comercial renderers: This is refering to renderers, which we
implemented for customer projects and which are not open source. We
currently do not sell licenses for any renderers. We do provide support
and/or development ressources to adapt existing renderers or even
develop new one. If you are interested in learning more about that,
please contact me. (https://www.eclipse.org/ecp/emfforms/communication.html)
Best regards
