Java Data Binding and Custom Converter -

-

i'm attempting bind atomicboolean "enabled" property of jcheckbox. since atomicboolean not replacement boolean i'm using custom converter. however, converter shown below results in classcastexception. why?

org.jdesktop.beansbinding.binding binding = org.jdesktop.beansbinding.bindings.createautobinding(org.jdesktop.beansbinding.autobinding.updatestrategy.read, isidle, org.jdesktop.beansbinding.objectproperty.create(), cornercb, org.jdesktop.beansbinding.beanproperty.create("enabled"));         binding.setconverter(new converter<atomicboolean, boolean>() {             @override             public boolean convertforward(atomicboolean value) {                 boolean b = value.get();                 return b;             }              @override             public atomicboolean convertreverse(boolean value) {                 return new atomicboolean(value);             }         });

resulting exception

java.lang.classcastexception         @ java.lang.class.cast(class.java:2990)         @ org.jdesktop.beansbinding.binding.convertforward(binding.java:1312)         @ org.jdesktop.beansbinding.binding.getsourcevaluefortarget(binding.java:844)         @ org.jdesktop.beansbinding.binding.refreshunmanaged(binding.java:1222)         @ org.jdesktop.beansbinding.binding.refresh(binding.java:1207)         @ org.jdesktop.beansbinding.binding.refreshandnotify(binding.java:1143)         @ org.jdesktop.beansbinding.autobinding.bindimpl(autobinding.java:197)         @ org.jdesktop.beansbinding.binding.bindunmanaged(binding.java:959)         @ org.jdesktop.beansbinding.binding.bind(binding.java:944)         @ org.jdesktop.beansbinding.bindinggroup.bind(bindinggroup.java:143)

that exception isn't coming code. it's happening here:

private final tv convertforward(sv value) {     if (converter == null) {         class<?> targettype = noprimitivetype(targetproperty.getwritetype(targetobject));         return (tv)targettype.cast(converter.defaultconvert(value, targettype));     }      return converter.convertforward(value); }

there couple of different maven artifacts have class in call class.cast() on line 1312. doesn't matter you're using. you'll need debugging. put breakpoint on line, , can trace call , see values being passed down , why exception happening. seems converter isn't being used reason, problem. it's trying cast atomicboolean boolean.

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.
