Title component NPE

Bug Report

Current Behavior I have a proxy title component based on v2 title. I am overriding its dialog to hide linkUrl. I have custom banner component. Inside of it i am including title component: <div data-sly-resource="${'title' @ resourceType='mysite/components/content/title', decoration=true}" ></div> I also have parsys: <div data-sly-resource="${'par' @ resourceType='wcm/foundation/components/parsys', decoration=true}" ></div>

So i drag and drop banner component on a page. It already has title component inside of it. But when i try to open dialog of title it throws NPE.

I guess it is because there is no title node, it is "synthetic" it will appear only when i configure and save it. But i cant do that because of npe. There is no null check after getResource call inside AllowedTitleSizesDataSourceServlet

Expected behavior/code Title component should be editable when included as data-sly-resource.

Environment

• AEM version and patch level (AEM 6.4.4)
• Core Components version (2.4.0)
• JRE version ( Java(TM) SE Runtime Environment (build 1.8.0_181-b13))

Possible Solution Check for null and if resource is null(synthetic) return some predefined allowed types

Additional context / Screenshots Add any other context about the problem here. If applicable, add screenshots to help explain.

I am also trying to use the Core component v2 directly in the HTL file of my component. <div data-sly-resource="${'title' @ resourceType='core/wcm/components/title/v1/title'}"></div> While trying to open the dialog, I get the same NPE
