Hi Martin, Oops, I didn't expect for the property node to give an error when used in a sub-panel, but it makes sense.
I only meant for the property node to be used when you are doing your editing. This allows you to run the VI, and the property node will line things up for you exactly. Then you save the VI, so that the VI is saved at that origin. When used as a sub-panel, it is the saved coords that cause the alignment to be as you want. The Property Node does not do anything. You could remove the property node after you run/save the VI. But I would keep it in just in case you accidently move the origin when editing the VI in the future. Instead, what I would do is wire the error out of the property node to "clear errors" VI found in the time & dialog palette so that you won't get your error.
