[EMFForms][RAP] No render found [message #1274509] Fri, 21 March 2014 11:23 Go to next message
Eclipse UserFriend
Hi there,

i try to use EMFForms in my RAP app. I created a "task" object of example model makeithappen. Than I'm passing the object to
ECPSWTViewRenderer.INSTANCE.render

When I open the view I get a NoRendererFoundException.

org.eclipse.emf.ecp.view.spi.renderer.: No renderer for View found.
	at org.eclipse.emf.ecp.view.spi.swt.SWTRendererFactory.render(SWTRendererFactory.java:110)
	at org.eclipse.emf.ecp.view.internal.swt.ECPSWTViewRendererImpl.render(ECPSWTViewRendererImpl.java:66)
	at org.eclipse.emf.ecp.view.internal.swt.ECPSWTViewRendererImpl.render(ECPSWTViewRendererImpl.java:56)
	at org.eclipse.emf.ecp.view.internal.swt.ECPSWTViewRendererImpl.render(ECPSWTViewRendererImpl.java:44)


Any ideas?

Now i played with my included bundles. I added all bundles with no validation issues to my launch conf. Now i receive: java.lang.NullPointerException: A null service reference is not allowed.

I'm kind of lost in all these bundles. What bundles do I need to run EMFForms in my RAP app? Is EMFForms working with RAP at all?

Hi Phil,
yes EMFForms is working on RAP.
Which version of ECP are you using?
Can you paste your exception here?

Cheers,
Eugen

Hi Eugen,

thanks for your quick answer. I'm using ecp 1.2.1. Now I try it by feature selection. Can you tell me which features I need for rap approach?

Thanks in advance
Philippe

Hi Phil,
you most probably checked out the ECP source code. Thus there should be a project called org.eclipse.emf.ecp.releng . In this project there should be a file called ecpDevelopmentDemo.launch . You can use this to launch a RAP application.

If you want to try to setup an own launch config based on features, I would start by selecting the org.eclipse.rap.equinox.target.feature and the org.eclipse.emf.ecp.rap.feature and org.eclipse.emf.ecp.rap.util.feature. After that press "Select Required". You most probably will also need the org.eclipse.emf.edit feature.

Nevertheless I would suggest to using the pre-configured launch config.

Cheers,
Eugen

Hi Phil,

do you only use EMF Forms, or also ECP?

Regards

Hi, I've used ecpDevelopmentDemo.launch. On the launch config 'Bundles' tab I've added my EMF plugins (model and edit). Also I've added org.eclipse.emf.ecp.ui.view.swt plugin.
But I got following exception.
Any idea?
Thanks.

Hi,
you are probably missing the org.eclipse.emf.ecp.view.model.provider.generator and org.eclipse.emf.ecp.view.model.provider.xmi bundles.
I will check the launch config why it is missing those.

Cheers,
Eugen

I've added them to launch config. But this time I got different error.
Thanks.

Hi,
you seam to be missing a renderer. Please check in you launch configuration if you added a *.swt bundle whenever you have selected a model bundle, e.g. if you selected the org.eclipse.emf.ecp.view.vertical.model bundle you must also add the org.eclipse.emf.ecp.view.vertical.swt bundle to your launch configuration.
