I bumped into the NullPointerException noted above. NP for the fix, but how to debug? Where do I find the source code for MyPanel_MyPanelUiBinderImpl.java:20?

09:19:50.084 [ERROR] [passparamtowidget] Unable to load module entry point class com.jeffdouglas.client.PassParamToWidget (see associated exception for details)

Hello Jeff,
thanks for your tutorials, it helped me a lot to understand basics of GWT and web development.
What I’d need is to pass an argument to the entry point from the URL. Something like: http://127.0.0.1:8888/GWT1.html?id=55
To know that id is 55. Is it possible?

Thank you.

Is there anyway that I can pass a parameter using UIBinder to a builtin Widget such as SplitLayoutPanel ? SplitLayoutPanel has a constructor parameter of splitterSize that can be set when creating the SplitLayoutPanel in java, i.e. new SplitLayoutPanel(5) will create a SplitLayoutPanel with a 5pixel wide splitter bar. Is it possible to do this using only UIBinder annotations ? With out directly calling the constructor in Java.
Maybe there should be constructor parameter type that we can reference in XML , for example etc ……
Thanks
CF

Why did you add the key word ‘provided=true’ in the line @UiField(provided=true) ? You didn’t add that in other locations.

I get an error trying to run this. NullPointerException in line 26 of MyPanel.java. initWidget(uiBinder.createAndBuildUi(this)

I had to change the first line of the MyPanel constructor to be:
myField = new Hidden() to get it to work.
