Ok, thanks John. I'm slowly learning this but it seems I have to stumble on
Within Workbench one can edit a package.m file by opening with the System
Editor, which I guess is the FE package editor. Then it is possible to add
Titles, Sections, Text cells etc. The result is that it can look pretty much
like a regular notebook. One can select all the Code cells and switch them
to Input cells, which will have line wrapping, edit them, and then switch
The FE editor comes up in a window outside of the Workbench panel, and the
editing is really being done outside of Workbench. Therefore, when one is
finished, Workbench says that the file is out of sync with the project
because it has been changed outside of the project. Therefore one has to
"Refresh" the package, or maybe one can "Refresh" the entire project. Then
Workbench will work properly. And InfoPaclet.m files will also display
One could also open the package again within Workbench by using the
Mathematica Source editor. The advantage of this is that you can have a
package that looks like regular notebooks and can be edited with either
One can generate a package.nb notebook by copying all the content in the
package.m file, say in the FE editor, and pasting it into a regular
notebook. Then select all the Input cells and convert them to StandardForm.
And conversely, one can generate a package.m file from the package.nb
notebook by opening a new package.m file, copying everything in package.nb
and pasting it into package.m. Then select all the Input cells and convert
their Style to Code cells. (Of course, one could also use the auto generate
So it seems you can have your cake and eat it too. One just has to know how
to go back and forth and remember to Refresh.
So my love-hate relationship with Workbench is presently back in the love
phase. Until the next stumble.

Code cells actually form the package code. Input cells remain evaluatable
the FE, but are commented out in the package so that they are not evaluated
The styles behind the scenes do this by setting (or not) the
option, so it's basically the same as working with auto-generated packages

Package files are text files. Since the package editor uses the text format
directly, rather than backing a source notebook file with a generated
file like auto-generated packages do, this means that you can edit those
files with anything. The FE adds a small amount of markup, but that markup
in clearly delineated comments which often actually help to annotate the
when it's edited with any other editor. And if you manually remove or alter
markup, the FE won't (or shouldn't, anyway) throw a conniption.

I can't say what happened here. Your description is too vague, and I don't
really know anything about the PacletInfo Editor. But if you want to send
your files and describe to me in more detail exactly what it was you did,
certainly take a look at it.
