Re: StockWatcher example. null pointer because root panel cannot find html element 'stockList'

I too faced a similar problem...but have corrected it...

I had to simply change the code given by Google tutorial to something like this...

From:
// Associate the Main panel with the HTML host page.
RootPanel.get("stockList").add(mainPanel);

Something like this..
// Associate the Main panel with the HTML host page.
RootPanel.get().add(mainPanel);


and the nullpointer Exception is no longer....

 line 67 ---->   RootPanel.get("stockList").add(mainPanel);


in the file StockWatcher.html:

   <div id="stockList"></div>

I used the commands in the tutorial:

C:\Projects\gwt-windows-1.5.0\StockWatcher>projectCreator -eclipse
StockWatcher -out StockWatcher
C:\Projects\gwt-windows-1.5.0\StockWatcher>applicationCreator -eclipse
StockWatcher -out StockWatcher
com.google.gwt.sample.stockwatcher.client.StockWatcher

It seems like a config thing. Any help appreciated.
thanks,
Anil
