lifecycle

I have a page containing a control called PhoneInfo.ascx. PhoneInfo is dynamically created using LoadControl() and then the initControl() function is called passing in an initialization object to set some initial textbox values within PhoneInfo. The user then changes these values and hits a submit button on the page which is wired up to the "submit_click" event. This event invokes the GetPhone() function within PhoneInfo. The returned value has all of the new user entered values except that the phoneId value (stored in ViewState and NOT edited by the user) always comes back as null. I believe

I have the following configuration for my MQueue: <jms:listener-container container-type="default" connection-factory="cachedConnectionFactory" acknowledge="auto"> <jms:listener id="myListenerId" destination="myDestination" ref="myListener" method="onMessage" /> </jms:listener-container> When I try to stop the reception of JMS messages, I write the following code jmsManagement = myProject.instance.getContext().getBean('myListenerId',Lifecycle.class); jmsManagement.stop(); PS : When I stop() my listener, the isRunning() return False, but I still get messages through the MQueue... the onMessage

Why is it that you need to call the super class in the android lifecycle? For example, in onCreate you need to call super.onCreate, or onDestroy super.onDestroy. It makes sure that any relevant lifecycle management code across the full class hierarchy gets invoked. If you have MyBaseActivity that extends Activity , and MySpecificActivity that extends MyBaseActivity , calling through to the lifecycle methods in the superclass at each level means MyBaseActivity will still be able to respond to lifecycle events. 来源： https://stackoverflow.com/questions/5395672/super-class-android-life-cycle

I understand pretty well about Android lifecycle. I post here because I've observed one weird behavior, anyway this is my own thought. My case is like this: One activity will use a simple layout with just a single EditText . In the activity onCreate method, i set some default text to the EditText and in later part of the method, assign a TextWatcher to the EditText so whenever user types in anything, i can response in my own way. Everything is alright until I rotate the screen. The TextWatcher callback starts to react against the code that initialize the EditText . According to the normal code

I'm getting an error message due to an async method issue. In my terminal I'm seeing: Warning: Can't call setState (or forceUpdate) on an unmounted component. This is a no-op, but it indicates a memory leak in your application. To fix, cancel all subscriptions and asynchronous tasks in the componentWillUnmount method. - node_modules/fbjs/lib/warning.js:33:20 in printWarning - node_modules/fbjs/lib/warning.js:57:25 in warning - node_modules/react-native/Libraries/Renderer/ReactNativeRenderer-dev.js:12196:6 in warnAboutUpdateOnUnmounted - node_modules/react-native/Libraries/Renderer

I would like to have an illustrative explanation about the difference between getValue() and getLocalValue() methods of UIInput components in the aspect of performing multiple field validation: jsf validate two fields in one time . What is the difference in usage of this methods if the fields are already validated? The ValueHolder API documentation is not very helpful in answering this. BalusC If the UIInput component has been validated beforehand and is marked invalid (i.e. isValid() method returns false ), then the getLocalValue() returns null , but the getValue() returns the old model value

I have recently migrated some of my projects to the shiny new Flex 4.6 SDK. I wasn't expecting much trouble since it was only a minor release. But as a matter of fact I got hundreds of errors all over the place. These errors would mostly come from Spark SkinnableComponent s; for example: override protected function getCurrentSkinState():String { return mySkinPart.someProperty ? "normal" : "someOtherState"; } would work just fine under 4.5, but would throw me a nullpointer error in 4.6. The reason is simple enough: in 4.6 getCurrentSkinState() is called before the skinparts are created, whereas

I've just downloaded the OEPE (Kepler) and installed m2e and m2e-wtp connectors. I found out that under this path: Preferences ->Maven->Lifecycle mappings->Open workspace lifecycle mapping data there is a preconfigured xml file which says that maven should ignore the compile goal for AspectJ and I assume that's why the AspectJ runtime libraries are not added to the project hence the project is not recognized as an AspectJ project by eclipse. <?xml version="1.0" encoding="UTF-8"?> <lifecycleMappingMetadata> <pluginExecutions> <pluginExecution> <pluginExecutionFilter> <groupId>org.codehaus.mojo<

I have a variable that I have successfully saved and restored using onSaveInstanceState @Override protected void onSaveInstanceState(Bundle outState) { super.onSaveInstanceState(outState); // the UI component values are saved here. outState.putDouble("VALUE", liter); Toast.makeText(this, "Activity state saved", Toast.LENGTH_LONG).show(); } But this only works if the activity is destroyed. I want to save the same variable by overriding the onPause() method and getting back when the activity is not not paused anymore any ideas on how to do this are greatly appreciated As you have discovered,

My end-goal is to have an application that runs a block of code when it (the application, not the activity) is opened up after being left ( back from home screen, etc... ) According to the Activity Lifecycle, this should be the onRestart() event on a per activity basis ( at least how I interpret it ) Both onRestart() and onResume() are being called whether I am returning to the Activity within the application (back button) AND when the app is called back up. Given this diagram I am interpreting it this way: RED = movement between activities within the application BLUE = moving to an activity
