----------------------------------------

Unfortunately, this happens most in the IDE - it takes some time to discover the problem, since you trusted in the IDE.

>             Project: Click
>          Issue Type: Improvement
>          Components: documentation

> For intermediate java programmer is common to do this trivial error:
> class com.xxxxxxxxClass {
> }
> instead of
> public class com.xxxxxxxxClass {
> }
> Causing this type of execption:
> Caused by: java.lang.IllegalAccessException: Class org.apache.click.util.PropertyUtils can not access a member of class com.xxxxxxxClass with modifiers "public"
> at sun.reflect.Reflection.ensureMemberAccess(Reflection.java:95)
> So, I'm suggesting the following entry on FAQ:
> question: can not access a member of with modifiers "public"
>  answer:
> If you get the following error in Click:
> java.lang.IllegalAccessException: Class org.apache.click.util.PropertyUtils can not access a member of class com.xxxxxClass with modifiers "public"
> it's likely because your class com.xxxxxxxxClass is not public. You just need to add a public keyword in front of the class definition
> public class com.xxxxxxxxAction {
> }
