TYPO3 Core

I am not sure if this should be considered a bug. The entered link in sys_redirect.target was wrong.

Possible improvements:¶

- If the link entered in sys_redirects.target is wrong, display this with a warning (!) in the form
- better errror handling so that excption is not thrown, but log message is generated

Reproduce (1):¶

1. Create a redirect with sys_redirect.target=" t3://page=uid=18&_language=1 "
2. Save the record: exception will be displayed, but record is saved nonetheless.

The exception also occurs if the record already exists and:

• reference index is updated
• a filter is entered in redirects module which has this entry as result.

Error message¶

Update index of table sys_redirect
