[Narasimha Narahari]

Hi,
I am getting a null pointer exception when i am trying to generate a pie3D. One of the responses has value 0 because of which i guess its throwing this exception. The following is the error i am getting

Are you using the 0.9.5 version. This was a problem in earlier versions but has been fixed in 0.9.4.

I meant to say it has been fixed in 0.9.5 and NOT fixed in 0.9.4.

[Jose Antonio Vargas A]

I'm having the same problem with the 3d chart using v0.9.4 and cewolf v0.8.8.

The thing is that I do not get the error while in Tomcat 4.0.6, but I do get it using Tomcat 4.1.x

Is there a workaround using v0.9.4 instead of v0.9.5?

Also, with some pie3d instances, I got the chart clipped.
