Glass Mapper Model too deep. Potential lazy loading loop exception after upgrading to version 4.3.4.196

Question

I updated the Glass Mapper version for our Sitecore 8.2 project from version 4.0.1.8 to version 4.3.4.196.

After upgrading Sitecore is still running, but our websites are throwing exceptions:

Model too deep. Potential lazy loading loop

I added the Cacheable property to the Models and I also had the Setting = SitecoreFieldSettings.DontLoadLazily on the Fields from before the upgrade. But no result, it keeps throwing this error.

My model structure has not changed, anyone any idea what is going on? Or maybe that ModelDepthCheck can be disabled?

Answer 1

Please see the release notes for 4.3 which explain how to remove the depth check: http://www.glass.lu/Blog/Release4-3

The depth check is designed to capture models where lazy loading is disabled but a loop might have been caused which would result in a stack overflow. However some models maybe deep enough anyway to cause the depth check to fire. Currently it is set to a depth of 8.
