Re: Can't Save Record Mandatory field is null

[Keisuke Miyako via 4D_Tech]

you can "export structure" and parse the xml.

I cannot find a way to search for fields with "Reject NULL Values" set to
true. Surely this must be possible, so can someone please let me know how
to do it?

Hello again,
I cannot find a way to search for fields with "Reject NULL Values" set to
true. Surely this must be possible, so can someone please let me know how
to do it?
Thank you,
Alan

Hello Sannyasin,
I just got bitten by this same issue, so thank you very much for sharing
the solution.
We had a field that was accidentally marked to 'Reject null input values'
over 15 months ago and today it started causing problems!
But we are back up and running after searching for this issue. I had only
looked at Mandatory fields previously.
Much appreciated,
Alan Tilson

Re: 4D <-> Development

[Jody Bevan via 4D_Tech]

Dave:

Thank you so much for that excellent description of the path you took. Though 
it is all hard work ahead doing it, as you point out, it will likely help 
getting my head wrapped around the new 4D language. For ADE (Argus Development 
Environment) I had the ADE create the documentation framework automatically for 
Users, Admins, and Developers. As my wife points out, I need to have the 
documentation on the web to be taken seriously today. So whether that is the 
first project I do, or the one for a current client I think that you have 
helped me make up my mind. I like that you even described the tools you are 
using, AND how you learned the languages.

I really liked Lightening, and Aparajita’s Active4D. They fit very nicely in 
with 4D. I think though I will try to go the harder route in the anticipation 
that it will take me longer, but will stand the test of time.

Thanks again for after a post so long ago that you thought to respond.

Jody
