illegalstateexception

问题 I am trying to run my first JSF application using RichFaces. Unfortunately the error below is being thrown. There is no bean added to my project. Also, there's no tags added yet. Just trying to run simple empty xhtml file. What is the problem? I'm using Eclipse Luna 4.4.2, GlassFish 4, and OSX. 2016-02-03T00:34:59.661+0200|Warning: StandardWrapperValve[Faces Servlet]: Servlet.service() for servlet Faces Servlet threw exception java.lang.IllegalStateException at com.sun.faces.context

问题 Can anyone determine what is going wrong, or give me any clues? I think it is within the current activity (CreateProfileActivity), in this buttonClick method: public void saveUserClick(View view){ saveUserDetails(); insertUserToDB(); Log.d("yo", "yoyoyo"); dbHelper.logDataBase(); } in particular, this line dbHelper.logDataBase(); Here is that methods declaration: public void logDataBase(){ // Getting all clothing items Log.d("Get database Items", "Getting all database items"); List

问题 I'm not sure why this is happening but I'm getting an error stating: Calling layout.removeAllViews(); still results in IllegalStateException: The specified child already has a parent. You must call removeView() on the child's parent first. The strange part is I've called: removeAllViews(); before adding a new one: @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.download); ... ImageView imageViewz = (ImageView)

问题 I'm trying to create a simple video recorder and here's my code in order that I'm calling it: protected boolean prepareForVideoRecording() { try { mCamera.unlock(); mMediaRecorder = new MediaRecorder(); mMediaRecorder.setCamera(mCamera); mMediaRecorder.setAudioSource(MediaRecorder.AudioSource.CAMCORDER); mMediaRecorder.setVideoSource(MediaRecorder.VideoSource.CAMERA); mMediaRecorder.setProfile(CamcorderProfile.get(CamcorderProfile.QUALITY_HIGH)); mMediaRecorder.setOutputFile

问题 I had a crash reported by an user (Samsung Galaxy S5, Android 4.4) and I do not understand what is happening. It seems imporbable but maybe some people have encountered the same problem, or similar. Here is the trace: java.lang.RuntimeException: An error occured while executing doInBackground() at android.os.AsyncTask$3.done(AsyncTask.java:300) at java.util.concurrent.FutureTask.finishCompletion(FutureTask.java:355) at java.util.concurrent.FutureTask.setException(FutureTask.java:222) at java

问题 Background I'm trying to check if a contact image exists for a specific contact (and later to actually get it, much later). the query should be as minimal as possible and avoid un-needed memory usage. I've figured out this probably isn't possible using the normal way, so for now I'm using: final Uri lookupUri = Uri.withAppendedPath(ContactsContract.Contacts.CONTENT_LOOKUP_URI, contactKey); final Cursor contactCur = mContentResolver.query(lookupUri, new String[] { ContactsContract.Contacts._ID

问题 Hi I am trying to display some marker points on a Google map v2. All is good until I found this bug. For some reason if I load the map with 2 pointers on it and then close it and reload it again I get this message: "IllegalStateException no included points" This error appears when I call the: LatLngBounds bounds = builder.build(); This is how I put the points on the map: // Point the map's listeners at the listeners implemented by the cluster // manager. googleMap.setOnMarkerClickListener

问题 My program seems to work quite well, but I keep getting "IllegalStateExceptions: RunnableQueue not started or has exited" from time to time, when I try to resize my component. I have set the documentState to ALWAYS_DYNAMIC and I have read that you are supposed to use the JSVGCanvas' UpdateManager and call invokelater(). I understand that it is available after the first time that gvtBuildCompleted(GVTTreeBuilderEvent e) is called, so I check whether it is running before I use it but I still

问题 I have a DialogFragment that nothing but make a Volley request and populate the data to a RecyclerView. I am launching (via a click on TextView link) this dialog from a fragment. When the dialog is launched for the first time, it launches and does what it's supposed to do, no hitch. Then I rotate the screen, launch the dialog again, and whoosh! I am greeted with "IllegalStateException: Activity has been destroyed". One weird thing about this error is that I am also launching this same

问题 I keep getting errors when trying to run my program even though when making the program in net beans I have no errors. It's only when I try to compile that 50 errors pop up. Someone explained that my JTextField wasn't attached to the Horizontal group and I thought I fixed it but it seems not. public class TrianglePerimeter extends javax.swing.JFrame { public TrianglePerimeter() { utilizeComponents(); } @SuppressWarnings("Not Checked") private void utilizeComponents() { sideOneInput = new
