As asked, reporting Unexpected error.

[Arynderquane]

Well i was refactoring my code, specifically changing name to id inside layouts. Logically the code appeared to be messy everywhere and i'm not concerned by this error, but since you're asking, i'm reporting :)
I'm using version 2.7.1.

Unexpected error. Please report an issue on AndroidAnnotations, with the following content: java.lang.NullPointerException

That's a known issue but since it's difficult to reproduce, the bug's still there...
Thanks to your explanation, it seems it's happening during layout refactoring. Do you think you could try to reproduce this bug in a smaller project ?

[DayS]

Could you also provide the line of code on which the error was thrown ?

[DayS]

Ok, so... In fact, it's dead simple to reproduce :)

Just create an activity like this :

@EActivity(R.layout.activity_issue_616)
public class ActivityIssue616 extends Activity {
    @Click(R.id.issue616Button)
    void buttonClicked() {
    }
}

With the layout :

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <Button
        android:id="@+id/issue616Button"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Button" />

</RelativeLayout>

Then, we just have to rename the id attribute in the layout to see the error.

As there is also a javac error because R.id.issue616Button is unkown, I think the annotation processing is still triggered but the method to extract annotation value seems to return null which is why we have a NullPointerException.
As we have a compiler error, I think we should just check the value and return an empty array if it's null.

Ho, and the bug is still here in 3.0

Should be fixed on 3.0
