view: Use of uninitialized value in string eq at /var/www/twiki/lib/TWiki/Users/TWikiUserMapping.pm line 471.

view: Can't call method "normalizeWebTopicName" on an undefined value at /var/www/twiki/lib/TWiki/Func.pm line 1306.


Errors occur in browser when trying to view a page.

I can't adequately explain why this problem occurs, except that it has to do with the TWiki singleton's constructor calling functions in other classes that refer to TWiki object properties that haven't been set yet.

Please review the attached patch; it should give a good overview.

This needs to be investigated. What is the {UserMappingManager} and {PasswordManager}?

I'm seeing the same issue with TWikiUserMapping.pm line 471 on a brand new 4.3.1 install. wiki admin doesn't generate the error, only users that are created generate them. It happens for every page turn. Seems like everything is working while still generating the error. I also had ApacheLogin set at one point, so I'm not sure if that contributed to the issue. I have the following config:

$TWiki::cfg{UserMappingManager} = 'TWiki::Users::TWikiUserMapping'; $TWiki::cfg{PasswordManager} = 'TWiki::Users::HtPasswdUser'; $TWiki::cfg{LoginManager} = 'TWiki::LoginManager::TemplateLogin';
