core
Is this a regression?
Yes
Description
Since I upgraded to v12.2.4 (from 11.2.14), my build fails because of a generic abstract component who's inherited by 2 other components. The build fails with the error "Failed to find exported name of node" on one of my model class used in the generic.
I found a few different ways to make this compile without the error :
- Remove the component inheritance or remove the generic in the
CommonComponent - Disable the AOT mode in the angular.json configuration file
- Disable the
fullTemplateTypeCheck,strictInjectionParametersandstrictTemplatesoptions in the tsconfig.json configuration file
To reproduce the issue :
git clone https://github.com/jdussouillez/angular-test.git \
&& cd angular-test \
&& git checkout bugs/generic-component-inheritance-aot-v12 \
&& npm ci \
&& ng buildPlease provide a link to a minimal reproduction of the bug
