problem using smart gwt 3.0 with minor changes to a project from showcase

[arvindikchari]

I am using Smart GWT 3.0- specifically I am working with the rotate sample that uses drawing class.

I have changed the triangle drawn, and instead want to show a image in its place- I want this image to rotate in the same way as the other shapes are rotated when the user clicks on slider ( as shown in showcase)

There is no error shown in eclipse after I have modified the code and saved it.

I have changed the triangle shape code and replaced it with the following--


DrawImage drawImg= new DrawImage();
drawImg.setSrc("other/earth.png");
drawImg.setDrawPane(drawPane);
drawImg.setLeft(100);
drawImg.setHeight(100);
drawImg.draw();


However an "Uncaught Exception" error is shown when I run GWT Dev mode and try to see the html page containing the drawings.

Given below is the error I get in Google Chrome when the app fails to run--

onModuleLoad() threw an exception
Exception while loading module com.arvindikchari.bspinner.client.Spinner. See Development Mode for details.

What do I have to do to correct this error?

arvindikchari: your report suggests you just don't have the Drawing module included properly. Make sure you have <inherits name="com.smartgwt.Drawing"/> in your .gwt.xml file, just before your entry-point definition. If that doesn't get things working, do a full GWT compile and fully clear your browser cache.

pboysen: there was an issue with images specified using [SKIN]-like relative paths - this has been addressed in 3.0p and 3.1d. Please retest with a nightly after 5/25
