VisualizationsForVaadin compile problem

Trying VisualiationsForVaadin with the Eclipse Vaadin plugin for the first time and I’m having compile problem:

I’m having this problem in our main project tree, but I reproduced this problem in a new Eclipse Vaadin project (used for the output in this posting).

In WebContent/WEB-INF/lib I have:

gwt-visualization.jar (version 1.0.2)
vaadin-6.6.0.jar
VaadinVisualizations2.1.jar

It seems like gwt-visualization.jar is not being included in the compile for some reason.

I’ve also tried gwt-visualization 1.1.0 - 1.1.2-rc2 and saw similar results but different missing classes:

You’re right. Somehow the visualization jar is missing from the GWT compilation classpath. The jar is in the right place though.

It shouldn’t really be needed, but you could try to add the dependency by hand to the .gwt.xml file in your project:

<inherits name='com.google.gwt.visualization.Visualization'/> (looks like that would be the file src/vortex/console/widgetset/Adminconsole2Widgetset.gwt.xml )

Some other debugging ideas: make sure the gwt-visualization.jar is not corrupted or anything and also turn on the “Verbose compilation output” in the Vaadin project preferences to get some more information about the environment/classpath.

I had a similar problem getting the widgets to compile with gwt-visualization.jar (version 1.0.2). The jar is actually missing a load of class files that seem to be referenced within the VaadinVisualizations jar. The compilation works with the gwt-visualization.jar (version 1.1.2). However there is an issue (on Chrome at least) with the graphs initially displaying. They appear to only display after you resize the page…
