Re: [JAVA3D] Possible Text2d Bug

I also ran into this recently under Java 1.4.0_01 and Java3D 1.3. I discovered that if I change the text to a live Text2D object, I run the risk of hitting this. I have found that if I define the initial text to be larger than what I'm changing the text to, I'm able to avoid the exception.

Roy,

I was confused,

but I discover this bug only happens under Java 1.4.

If you use Java 1.3.1 there is no exceptions.

Se below :

Using Java 1.3 (sucessful) :

java -showversion -Dj3d.debug=true Text2dTest2

java version "1.3.1_02"

Hi Alessandro,
Thanks for responding. I tried adding those lines and I still got the exception. Then I tried using your code and I still got the exception. What am I missing here?
It also doesn't seem like the type of exception I'd get if I didn't have a capability set.

Hi, Roy !
There is no Text2D bug.
you just forget to add the following lines :
text.setCapability( Shape3D.ALLOW_GEOMETRY_READ);
text.setCapability( Shape3D.ALLOW_GEOMETRY_WRITE);
See your code working in the zip file ;)
