[chirp_devel] Issue with mem.immutable and exporting to CSV files

[Jim Unroe]

In a recently submitted bug report (Bug #9748) it was mentioned that
upon attempting to export the tab the following error appears.

"There was an error during export: Field power is not mutable on this memory"

This appears to be related to this bit of code.

        if mem.number <= 30 and self._gmrs:
            GMRS_IMMUTABLE = ["freq", "duplex", "offset"]
            if mem.number >= 8 and mem.number <= 14:
                mem.immutable = GMRS_IMMUTABLE + ["mode", "power"]
            else:
                mem.immutable = GMRS_IMMUTABLE

The error appears while CHIRP while building the data liste for the
"Export to File" dialog. Once it gets to channel 8 (the first in a
group of 7 channels which must remain set to Low power), the error is
triggered.

Removing "power" from the GMRS_IMMUTABLE list eliminates the error.

What seems odd to me is that the transmit power level is not even
saved to a CSV file so I don't understand why it would have anything
to do with exporting data to a CSV file.

I would like to come up with a solution to this issue without removing
"power" from the list.

Does anyone have any ideas?

Thanks,
