Hi,

I would like to open a generic project/file browser in importURI content assist for users to select the file to be imported.

could someone point me how to do this?

regards,

Cristiano

I've found this article: http://zarnekow.blogspot.com.br/2011/06/customizing-content-assist-with-xtext.html

I'll investigate if I can use that same approach to open a file browser dialog.

Yep, the same approach have worked. Thanks Sebastian !
This is the method that I had to modify:

	public void completeImport_ImportURI(EObject model, Assignment assignment,
			final ContentAssistContext context,
			ICompletionProposalAcceptor acceptor) {

		ConfigurableCompletionProposal pickModelFile = (ConfigurableCompletionProposal) createCompletionProposal(
				"Pick a model file...", context);
		if (pickModelFile != null) {
			pickModelFile.setTextApplier(new ReplacementTextApplier() {

				@Override
				public String getActualReplacementString(
						ConfigurableCompletionProposal proposal) {
					Display display = context.getViewer().getTextWidget()
							.getDisplay();

					FilteredResourcesSelectionDialog dialog = new FilteredResourcesSelectionDialog(
							display.getActiveShell(), false, ResourcesPlugin
									.getWorkspace().getRoot(), IResource.FILE);
					dialog.setBlockOnOpen(true);
					dialog.setInitialPattern("*.riskModel");
					dialog.setMessage("Choose the model file that you want to have access in this model.");
					dialog.setTitle("Model Selection");
					dialog.open();

					File result = (File) dialog.getResult()[0];

					return "\"" + result.getLocationURI() + "\"";
				}
			});
			acceptor.accept(pickModelFile);
		}
	}
