Yup, that's the discussion I mentioned in a different message.

Maybe LyX could check whether the label is referring to the section or not. Or more easily to implement, I guess, check whether the label is inserted at the beginning of a default paragraph right after the \subsection. This would make both of our suggestions supported.

It is not very easy, we are not completely sure of what we want.

Maybe worth changing that in the documentation files then.

Yes that seems a bit nicer.
Maybe LyX could automatically put labels after the \section{} when it is
put in the same line. But I don't know whether this would have other
undesired consequences.

I used to insert section labels right after the heading:

section headings with:
\usepackage{sectsty}
\sectionfont{\MakeUppercase}
I guess the error occurs for the same reason as
\MakeUppercase{\label{sec:Some-heading}} generates an error.

Hi Daniel,
I am not quite sure what you mean.
But this is how I insert a section:
I type : 'New Section' as a name
With the cursor somewhere inside/before/behind that name I select: 'Section'
And I get: '3.8 Section Extra' in the appropriate format
Selecting 'Section*' would do the same without numbering

Yes, it can cause other problems too. The root cause is that \section is
a "moving argument". You really don't want to put anything else in
there. Though I'll confess I sometimes do.

You can also just put the label at the beginning of the text. If there's
no such text (if the first thing is a \subsection), then you can put it
