Android 3.0 Couldn't read row#, column# from cursor window -

-

i have application runs fine on android 2.1, when trying transition 3.0 cursor error i'm not familar with.

java.lang.illegalstateexception: couldn't read row0, column -1 cursor window. make sure cursor initialized correctly before accessing data it.

all data storred in sqlite database , code works fine in android 2.1. cursor have initialized differently in android 3.0?

listed below code.

private void opengroupdata(){ sqlitedatabase db = openorcreatedatabase(database_name,context.mode_private,null); cursor cur = db.rawquery("select groupid properties group groupid" + ";" , null); linearlayout glayout = (linearlayout) findviewbyid(r.id.grouplayout); linearlayout gwindow = (linearlayout) findviewbyid(r.id.groupwindow);  textview data = new textview(this); glayout.addview(data); data.settext(""); int id = cur.getcolumnindex("groupid"); int idvalue;  setrequestedorientation(activityinfo.screen_orientation_user);  try{     // check if our result valid.     cur.movetofirst();     if (cur != null) {          // loop through results         {data = new textview(this);             data.settextsize(20);         data.setclickable(true);         data.setonclicklistener(new onclicklistener() {             @override             public void onclick(view v) {               groupclick(v);             }           });         glayout.addview(data);         idvalue = cur.getint(id);         data.setid(idvalue);         data.settext("group: " + idvalue);         }while(cur.movetonext());         }          cur.close();         db.close();         }   catch(exception e) {             toast.maketext(getapplicationcontext(), "open group exception: " + e.tostring(), toast.length_short).show();         }  }

i ran same error message earlier day. turned out made typo in column name. so, if still applies, go , check column name typo's. note case sensitive aswell. error me along lines of:

//trew error c.getcolumnindex("articlenumber");  //was correct c.getcolumnindex("articlenumber");

actionscript 3 - TweenLite does not work with object -

-
i got following problem: i have object called tempscore game. this object blitted canvas renderer via copypixels method. object not display object. it's score-object (self made). score-object extends object called basicblitarrayobject. basicblitarrayobject extends eventdispatcher (therefore no display object). i tried apply several different tweenlite-plugins tempscore-object (i.e. transformaroundcenter, colormatrixfilter, etc.). nothing happens. absolutely nothing. sometimes error messages (when plugin requires display object , object not display object). far good. according greensock (maker of tweenlite) engine can tween numeric property of object. when plugin transformaroundcenter requires display object tweening have modify plugin working non-display object (tempscore). can't because it's way hard me. my game rests upon code: http://www.8bitrocket.com/book/ch11_blastermines.zip try apply tweenlite object called tempmine inside game class blastermines.
