[pmwiki-users] PmForms and Saving Select Values

I'm replying to this in the hopes that it helps someone who does the 
same daft thing I did...

The problem here was nothing to do with select lists. In fact no 
variables were being written on a re-save.

The initial save worked. Changing values in the base page (outside of 
the form) worked: the values were read in by the form. Trying to change 
values inside the form did not work -- they were not rewritten to the 
target page.

Turns out I had done two things wrong:
1] I hadn't included a (:messages:) directive on the form used to show 
existing data -- the redirect form.
2] I was saving data to another page -- one specified by the value in a 
form field. One of the field validation routines checked to see if the 
savedata page already exists, and throws an error if a page does exist. 
This is good for initial entry. However, subsequent saves will try to 
save data to a page that already exist, and so throw an error... which I 
didn't see because of [1].

1] Add an (:message:) directive to the redirect form.
2] Change the validation routine. If the saveto page is the same as the 
current page, then do not throw an error.
