System Information
all

Blender Version
blender-2.70-6aa75d3-win64

Short description of error
All happens when you render by pressing the render button in the Compositor.
Two issues here:

1.Pressing the little Render button on a Render Layer in the compositor does render the layer.

But is shows a blank final result even though Compositing is disabled on other scenes.

2.While rendering a render layer the tiles are not shown.

Also the rendering text (time, memory, samples, etc) is missing.

Exact steps for others to reproduce the error
Check attached blend and image.

Thank you.

Can confirm the issue (and behavior in 2.69 is not better, even worse, actually, does not show at all render of layers).

You wouldn't see the render result for another scene in the image editor when the render is done. This is a design limitation -- image editor shows render result for an active scene only.

Missing tiles highlight is indeed interesting issue and will look into it.

Fixed the tiles in 64e7065. Missing display after the render is not a bug, but how current design works -- it displays render result of an active scene. Could be changed perhaps, but that'd be considered a TODO.

Thanks for the report, closing it now.

Thank you sergey.

However, even though this is a design limitation, when you press the little Render Layer button in the Compositor, the artist expects to see that render layer.
Instead it show the final render of the active scene. This is confusing for the artist and it's perceived as a bug/issue.

This was so annoying that I had to report it. Hopefully it will be fixed as well.

This is intended -- this way you can re-render the node in the compo and see the final compo result. Might not meet some particular expectation, but that's what it's intended to do -- always show final render for the active scene.

In practice it happens that you are always interested in that render layer when you click the little button to rerender it and do not expect to see the final result of the active scene. Specially when other render layers have not been rendered yet the compo will just show blank or incorrect result.

Can live with it though, thank you.
