JSF bypassupdates - Examine

When we use bypassupdates we can able to skip the model update phase alone while all other 5 phases among 6 will be executed by JSF framework.

JSF Phases:
1. Restore View Phase
2. Apply Request Values Phase
3. Covert and Validations Phase
4. Update Model Values Phase
5. Invoke Application Phase
6. Render Response Phase

When bypassupdates is defined, then JSF will skip execution of Phase 4
