But there is no MM with ID 0 ... it starts by 1.

Steps to reproduce

1. installed fresh MM via composer (bundle_all)
2. create a new MM with 'Title', 'Alias' and 'Notes' as attributes
3. a.s.o see https://de.contaowiki.org/MetaModels_Beispiel_2

   Describe the behaviour of the application

   • Listview works great
   • produced links are looking great
   • by klicking these the fatal error occures

do you work with a multilanguage metamodels?

[michaelgawlik]

no,

normaly I check translation, choose 'German', check fallback language and thats it.

so I read about the 'alias - translation' issue and create a new MM without any translation box checked.

same behavior.

[zonky2]

its possible to post your filter rule(s) as screenshot

here it is:

[michaelgawlik]

checked it at home on another project (same contao, dcg and mm-versions) - can't reproduce the error.

[zonky2]

hmm... may be "make new" - https://community.contao.org/de/showthread.php?45309-Contao-2-11-x-Detailseite-zeigt-nur-noch-Fehler-nach-dem-L%F6schen-eines-Kind-Models&p=293078&viewfull=1#post293078

I removed Metamodels + my mm_tables completly... but I left different modules (mm lists) on some sites. Not those that I used.

Now I cleaned up a bit better (deleted every mm-list (ce) + all mm-modules) ... et voilà - it works!

[zonky2]

hmm..? magic...
