Automatic validation on Save EMF model [message #1766671]

Hi all,

I added extra validation to my tree generated editor with EVL. This validation is only executed when the user clicks the "validate" button and I would like to validate the model automatically when the user saves it.

I came across this solution (https://stackoverflow.com/questions/8594212/how-to-programmatically-trigger-validation-of-emf-model) but I don't know how to apply it... Can anyone help me? Is this a good solution?

Thanks,

Cheers,
Sara

I'm not sure what this "validate" button is. The generated editor doesn't have such a thing, but it does have a validate action in the context menu for the selected objects as implemented by org.eclipse.emf.edit.ui.action.ValidateAction.run(). You could invoke that when the generated editor's XyzEditor.doSave(IProgressMonitor) is called.

Hi Ed,

Thanks for your message.

Yes, "validate" action. I added the ValidateAction.run() to this method on one of the Editors but nothing happened...

protected void doSaveAs(URI uri, IEditorInput editorInput) {
(editingDomain.getResourceSet().getResources().get(0)).setURI(uri);
setInputWithNotify(editorInput);
setPartName(editorInput.getName());
IProgressMonitor progressMonitor =
getActionBars().getStatusLineManager() != null ?
getActionBars().getStatusLineManager().getProgressMonitor() :
new NullProgressMonitor();
doSave(progressMonitor);
ValidateAction.run();
}

What am I doing wrong? Thanks

Cheers,
Sara

It's not a static method; does this even compile? I doubt it. Also, the action operates on the selection and it listens to selection changes, so you'd need logic for org.eclipse.emf.edit.ui.action.ValidateAction.updateSelection(IStructuredSelection) as well.

Do you have any example on how can I do that? Thanks
