judy guglielmin commented on JBSEAM-2851:
-----------------------------------------

Since not every project will require this jar, should it then be included in every seam-gen generated application?

>             Project: Seam
>          Issue Type: Bug

> I created a new project using seam-gen tools on a new project. 
> During the seam setup phase, I specified the latest version of ICEFaces.
> Everything went well and the default pages generated with seam-gen works properly.
> I tried to insert the JCharts component from ICEFaces to draw a simple 3D Pie Chart
> with the following code in home.xhtml
>  <ice:form>
>             <ice:panelGrid columns="2" columnClasses="leftMenu, leftMenu" rendered="#{identity.loggedIn}">
>                 <ice:outputChart type="pie3d"
>                                  chartTitle="Network Health"
>                                  labels="OK,WARN,ERROR,FATAL"
>                                  data="80,10,5,5"
>                                  colors="green,yellow,orange,red"
>                         />
>             </ice:panelGrid>

> I managed to fix the issue by
> - copying krysalis-jCharts-1.0.0-alpha-1.jar from ${icefaces.home}/lib to myproject/lib folder
> - updating my build.xml in the EAR target, by adding an " <include name="lib/krysalis-jCharts-1.0.0-alpha-1.jar"/>" 
>   in the EAR target in the fileset
> I don't know very well seam-gen but it seems that it's a small bug
> in one of the template build.xml defined in seam-gen folder.
> Hope it will help someone
