Summary:

My app, Viewfinder (http://connectedflow.com/viewfinder), uses AMWorkflow to communicate with Keynote (the workflow is attached). When I enable the app sandbox under Lion, the workflow does not run as expected.

Steps to Reproduce:

The following code is used to load a workflow from the app bundle and run it, passing in a file URL to a photo that has been downloaded:

+ (void)sendFileToKeynote:(NSURL *)pathURL;
{
	NSURL *url = [[NSBundle mainBundle] URLForResource: @"CreateKeynoteSlides" withExtension: @"workflow"];
	if(url) {
		NSError *workflowError = nil;
		id success = [AMWorkflow runWorkflowAtURL: url withInput: [pathURL path] error: &workflowError];
		if(!success && workflowError)
			[NSApp presentError: workflowError];
	}	
}

Expected Results:

Expected that the workflow would run and communicate correctly with Keynote.

Actual Results:

The workflow does not run and Console reports:

2011-07-01 10:31:20.352 Automator Runner[1548:707] Automator Runner is unable to establish a connection to the delegate.

Regression:

The workflow runs correctly on Lion with sandbox disabled and on Snow Leopard.

Notes:

I request the following entitlements in my app: app-sandbox, assets.pictures.write, files.downloads.read-write, network.client. I have tried adding temporary-exception.apple-events but this doesn't help.
