It seems that your question is not generic. We will be able to help you if you send us a small sample project along with a reproduction scenario that demonstrates the issue.

why this action=“windowCommitAndClose” gives null error ?

Of course the windowCommitAndClose action should not give the null error.
Your screens are quite complicated so we cannot explain why the problem appears without reproducing. We need to know at least how your entities source code looks like. So it would be helpful to get from you a small sample project.

here is the entity source code looks likeentitysource.zip (2.2 KB) …

The problem occurs due this delegate in the GoodEdit controller because its returning value is null:

    @Install(target = Target.DATA_CONTEXT)
    private Set<Entity> commitDelegate(CommitContext commitContext) {
        return null;
    }

You should remove or comment this code.

Nadezhda.
