Hi Robert, I need to implement model management where part of the models can be preloaded and precompiled and others can be loaded and compiled on demand. I was thinking of (re)using the databasepager for this, but I am not sure if this collides with the paging management. Are you planning to replace the databasepager internal load compilation with you new framework?
