Aw: Re: Strange History Behaviour
We just made a custom PlaceController and Historian to share some log
messages. Most of the google methods are private so that we can't just
override them implementing our log messages.
You mentioned GWT.setUncaughtExceptionHandler and i already placed it in my
code. But it may be the wrong place. Where do i have to place it to catch
all the exceptions mentioned?
But maybe our placecontroller puts some magic in there:
public DfsPlaceController(EventBus eventBus) {
super(eventBus);
}
public DfsPlaceController(EventBus eventBus, Delegate delegate) {
super(eventBus, delegate);
}
protected BreadcrumbBar createBreadcrumbBar() {
BreadcrumbBar breadcrumbBar = new BreadcrumbBar();
return breadcrumbBar;
}
@Override
public void goTo(Place newPlace) {
LOG.debug(goTo: + newPlace);
super.goTo(newPlace);
updateBreadcrumbBar(newPlace);
}
public void updateBreadcrumbBar() {
updateBreadcrumbBar(getWhere());
}
protected void updateBreadcrumbBar(Place place) {
try {
RootPanel breadcrumbRootPanel = RootPanel.get(breadcrumb);
if (breadcrumbRootPanel.getWidgetCount() == 0) {
LOG.debug(#updateBreadcrumbBar: No breadcrumb rootpanel
available.);
return;
}
Widget widget = breadcrumbRootPanel.getWidget(0);
if (!(widget instanceof BreadcrumbBar)) {
LOG.debug(#updateBreadcrumbBar: The first widget is not the
breadcrumb bar.);
return;
}
BreadcrumbBar breadcrumbBar = (BreadcrumbBar) widget;
BreadcrumbItem[] items = BreadcrumbBar.NO_BREADCRUMB_ITEMS;
if (place instanceof AbstractPlace) {
AbstractPlace abstractPlace = (AbstractPlace) place;
items = abstractPlace.getBreadcrumbItems();
}
breadcrumbBar.setBreadcrumbItems(items);
} catch (Exception ex) {
LOG.error(Unable to update breadcrumb bar., ex);
}
}

Aw: Re: Strange History Behaviour
UPDATE:
after try catching in my AbstractClientFactory i found something:
protected EventBus createEventBus() {
return new SimpleEventBus() {
@Override
public void fireEvent(Event? event) {
try {
LOG.debug(#fireEvent(Event? event): + event != null ?
event.toDebugString() : null);
super.fireEvent(event);
}catch(Exception e){
LOG.error(fire event failed: +
e.getCause().getMessage());
}
}
@Override
public void fireEvent(GwtEvent? event) {
try {
LOG.debug(#fireEvent(GwtEvent? event) + event != null ?
event.toDebugString() : null);
super.fireEvent(event);
}catch(Exception e){
LOG.error(fire gwtevent failed: +
e.getCause().getMessage());
}
}
};
}
like you said the inner class (in this case the new SimpleEventBus) is the
problem. fireEvent(Event? event) runs in my catch method. Problem is that
the exception just says that i should check the umbrella exception for the
cause. I don't know how to get this one? Or is this the point where i should
place my GWT.setUncaughtExceptionHandler?

Re: Aw: Re: Strange History Behaviour
try {
super.fireEvent(event);
} catch (UmbrellaException ue) {
for (Throwable t : ue.getCauses()) {
// here, use your code that prints the stack-trace; and if it's not
enough, loop over the getCause() hierarchy
}
}
An UncaughtExceptionHandler is a global catch: basically, your GWT code is
run in a big try/catch, so any exception you don't catch will go to your
UncaughtExceptionHandler (if you set one; or they'll generate JavaScript
errors in your browser console)

Aw: Re: Strange History Behaviour
I solved it You won't believe it... My View is currently using a third party calendar which needs to be implemented via native js. Deep in my UmbrellaExceptions I found something like $wnd.Calendar is null or wrong type. However this was firing an event which got recognized by GWT an encapsulated in about 10 UmbrellaExceptions... I also didn't find it because I casted to UmbrellaException from gwt shared package but it was from bindery package shared ;) Crazy stuff but thx for your help Thomas. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Aw: Re: Strange History Behaviour
This showed me the root of the problem ;)
import com.google.web.bindery.event.shared.UmbrellaException;
...
...
private void checkAndPrintException(Throwable ex) {
if(ex instanceof UmbrellaException){
LOG.debug(UMBRELLA EXCEPTION FOUND);
UmbrellaException umbEx = (UmbrellaException)ex;
for(Throwable t: umbEx.getCauses()){
if(t != null){
checkAndPrintException(t);
LOG.debug(Throwable caught: + t.getMessage());
}
}
}
}
