Explain the working of execution phase in JSF.

In this, when the first request is made, then the application view is built or restored. When the other requests are made, then the other actions are performed. The execution phase is further divided into various sub-phases which are as follows:

• Restore view phase
• Apply request value phase
• Process validation phase
• Update model values phase
• Invoke application phase
• Render response phase

Various actions which are performed are- applying of request parameter values, conversions, and validations of component values, updating managed beans, etc.
