SID-00727: Submitting a Form gives errors

Status:	Unanswered	TWiki version:	4.3.2	Perl version:	Perl 5.10.0
Category:	FormPlugin	Server OS:	Ubuntu 9.10	Last update:	16 years ago

I'm getting the following error when I submit even the most basic form:

TWiki detected an internal error - please check your TWiki logs and webserver logs for more information.
Can't use an undefined value as an ARRAY reference

In the apache logs I find the following:

Any ideas on what the issue is?

Discussion and Answer

Hello Bernd,

i just want to say that I got the same problem today.

I found out that when I skip all "mandatory" parameters from my form the error is gone.

Any further help on this issue is really appreciated.

Looks like an issue with AnyWikiDrawPlugin and FormPlugin, possibly by a version mismatch between TWiki and the plugins. Disable those plugin in configure to verify.

The problem definitely seems to be with the keyword "mandatory" as soon as it appears in any of the form elements I get the error: undefined value as an ARRAY reference

By disabling the AnyWikiDrawPlugin the first error in the log file disappears, but I still get the ARRAY reference error
