Hi all,

I am working on 5.0.

I am using BrowserField in my app to load an URL. while refrehsing the content it is throwing illegalstateexception.

anybody have any ideas regarding this??

the following is the code

btnRefresh.setChangeListener(new FieldChangeListener()
		{	
			public void fieldChanged(Field field, int context) 
			{
				try
				{
// throwingException			browser.refresh();
				}catch(Exception e)
				{
					Tools.print("XCO:MyBrowserFieldScreen:Refresh: Error" + e.toString());
				}
			}
		});

While debugging i found that an error is throwing at the line

BrowserField.deleteAll();

actually am not adding any fields to browser. But somehow it is throwing me error, while calling

browser.refresh();

browser.forward();

browser.back();

methods..

maybe an eventlock problem? what is the detail message of the exception?

try to run it in an invokelater.

Thanks simon,

am calling this browserfield screen in eventlock.

the following is the error msg:

XCO:MyBrowserFieldScreen:Refresh: Errorjava.lang.IllegalStateException: tried to remove FieldWithFocus

actually am placing the browser.refresh() in try/catch, still a simulator crash is happening and when i click on "continue"  the control is back to app.

i will try with invokelater and let you know the latest result.

i know the "delete field with focus" error. try to set the focus on one of your own fields before executing deleteAll

[Blanc]

actually the focus is on a custom button.

i have back, next, refresh as custom buttons and am calling the browser.back(), browser.refresh() in their fieldChangeListeners.

am not at all trying to delete any field while refreshing/back/next. so can you tell a litle more over

"try to set the focus on one of your own fields before executing deleteAll"

Hi simon,

i tried with what you said. i removed the eventlock while pushing the screen and now pushing the screen in the invokelater... still the same problem.

the following is the code

UiApplication.getUiApplication().invokeLater(new Runnable()
				{
					public void run()
					{
						MyBrowserFieldScreen screen = new MyBrowserFieldScreen(clikthruURL);
						TransitionContext transitionContextIn = new TransitionContext(TransitionContext.TRANSITION_SLIDE);
				        transitionContextIn.setIntAttribute(TransitionContext.ATTR_DURATION, 300);
				        transitionContextIn.setIntAttribute(TransitionContext.ATTR_DIRECTION, TransitionContext.DIRECTION_UP);              
				         
				        TransitionContext transitionContextOut = new TransitionContext(TransitionContext.TRANSITION_SLIDE);
				        transitionContextOut.setIntAttribute(TransitionContext.ATTR_DURATION, 300);
				        transitionContextOut.setIntAttribute(TransitionContext.ATTR_DIRECTION, TransitionContext.DIRECTION_DOWN);                                                            
				        transitionContextOut.setIntAttribute(TransitionContext.ATTR_KIND, TransitionContext.KIND_OUT);                
				                          
				        UiEngineInstance engine = Ui.getUiEngineInstance();
				        
				        engine.setTransition(null, screen, UiEngineInstance.TRIGGER_PUSH, transitionContextIn);
				        engine.setTransition(screen, null, UiEngineInstance.TRIGGER_POP, transitionContextOut);
				        
						UiApplication.getUiApplication().pushScreen(screen);
					}
				});

I have had similar problems with BrowserField, which I "fixed" by setting the focus back on the BrowserField before doing an action on it.  Try that.

working peter!!!

thanks!!

thanks simon.

once again thankU peter!!

but when i did a monkey testing on refresh button, it crashed throwing the same error!!

JVM error: 104

uncaught: IllegalStateException:

can you tell me why it is happening??

[peter_strange]

Refresh button?

Just to confirm, my code looks like

browserField.setFocus(); // Overcome random BrowserField bug

browserField.refresh();
