Re: Is it the best practice to put the loadingMessage code in the prepareFromRequest method in (GWTP)

I solved the problem, just put the callingMethod inside onReset, then it will be fine cos prepareFromRequest was called too early that some how other widget has not been bound yet & that causing the problem. This should work in all browser.

String item="";  @Override  public void prepareFromRequest(PlaceRequest request){           super.prepareFromRequest(request);           item=request.getParameter("item", "");    }    @Override  public voi onReset{           super.onReset();           addToPopupSlot(loadingPresenter);           GetData action=new GetData(item);           dispatchAsync.execute(action, getDataCallback);  }

I want to check the data at the time the page got loaded. I also want to put the loading indicator popup when checking data so that user will know that the page is loading data.

Look at this code:

@Override  public void prepareFromRequest(PlaceRequest request){           super.prepareFromRequest(request);           addToPopupSlot(loadingPresenter);           GetData action=new GetData();           dispatchAsync.execute(action, getDataCallback);  }  private AsyncCallback<GetDataResult> getDataCallback=new AsyncCallback<GetDataResult>(){          @Override          public void onFailure(Throwable caught) {              // TODO Auto-generated method stub              loadingPresenter.hide();          }            @Override          public void onSuccess(GetDataResult result) {              // TODO Auto-generated method stub              loadingPresenter.hide();                      //code to show data here          }  }  

OK, this code works fine in IE and in Firefox, but not ok in Chrome. That is:

In Chrome, after refreshing the page, the indicator did not hide though all data was showed correctly. In IE & Firefox the the indicator got hided properly.

I think there something wrong with Chrome somehow they can't call the loadingPresenter.hide();

What should I do? I don't think I should remove the loadingPresenter cos the getData method also was called when user clicking a button, so i need it to indicate the data is loading. But if i uses loadingPresenter then i can't run in Chrome.

So what should I do?
