I have this template for single field edit an integer column:

program:
	if raw_field('#percentread') ==# '0' then '1'
	fi

However this turns everything else into undefined. I noticed the template tester returned a blank value when making the template but i was not expecting it to change.

This worked and did not change other values:

program:
	if raw_field('#percentread') ==# '0' then '1'
	else raw_field('#percentread')
	fi

Is this expected behaviour? I would think that unless the template had else '' for a deliberate null the user would want it to remain the same. Though perhaps it can't tell the difference between a deliberate null and no output.
