I've worked around this by tackling the issue a different way:
- disable the delete button on the grid altogether with deletable=False
- selectively enable it in edit mode for records that are
safe/appropriate to delete
Maybe I should have done it this way to begin with - as it is nicer if
the user only sees actions that are going to work.

I am attempting to implement a check that allows deletes only under
some circumstances. I figured I would do this via the ondelete arg in
the grid. Unfortunately I have run into a few stumbling blocks with this:
1/ The 1.99.4 code is busted - references 'ret' before it is defined
Fortunately a simple fix (I think you guys have done something like
this in trunk) -
sqlhtml.py:1294
if ondelete:
#ondelete(table,request.args[-1],ret)
ondelete(table,request.args[-1])
2/ The ondelete function is only called from the main grid delete
action, not the delete checkbox in edit mode
I would be great if the logic could be applied there too - otherwise I
guess I can workaround by switching the delete option off in the edit
screen.
3/ Am unclear about how to signal back that I want delete to stop
I figure I am just being dense in this case, but ondelete function
accepts table and row id variables (not a form) so I don't see any way
to set the form's error status.
Thanks for your help
