java.lang.NullPointerException at com.sun.faces.lifecycle.ApplyRequestValuesPhase.execute

Question

since I deployed a new version of my application I get a weird error message which will be send every 20-30minutes. I have no clue how to debug it because it doesn't show a lot of information. Maybe you can help me out here.

javax.faces.FacesException

Please tell the exact Mojarra version. Then we can just read line 78 of its `ApplyRequestValuesPhase` class to learn what exactly is `null` over there where the code didn't expect that. — BalusC, Mar 01 '16 at 11:22

@EJP: I consider that dupe only applicable if NPE is coming from user's own code. — BalusC, Mar 02 '16 at 22:33
Manu, whoa, in [that line](http://grepcode.com/file/repo1.maven.org/maven2/org.glassfish/javax.faces/2.2.10/com/sun/faces/lifecycle/ApplyRequestValuesPhase.java#78) it's an `UIComponent` instance of the JSF component tree which is being null. This really stinks. To start, are you using `binding` anywhere and/or programmatically manipulating the component tree or even referencing the entire component tree in view/session/application scope in some way? If so, stop doing that and carefully read this: http://stackoverflow.com/q/14911158 — BalusC, Mar 02 '16 at 22:34
@BalusC: I checked my entire code and I'm not making use of any binding. Is there any way to get more details about this bug because right now I'm not able to detect the issue? — ManuPanu, Mar 12 '16 at 12:38
Ok I looked into my logfile and before this error there is another log entry: [WARNING] [] [javax.enterprise.r$ Unable to attach AddRemoveListener to UIViewRoot because it is null]] -- Still not found the error — ManuPanu, Apr 17 '16 at 11:43
