Okay, I'm not sure if there are updates, but here's my take:
In OrthoViewpoint.java,
This code (XML output) looks like this:
if ((((getFieldOfView().length > 0)
).equals(FIELDOFVIEW_DEFAULT_VALUE)) ||
!ConfigurationProperties.getStripDefaultAttributes()) /* ArrayList .x3d
compare */ && !hasUSE())
{
stringX3D.append("
fieldOfView='").append(MFFloat.toString(getFieldOfView())).append("'");
}
The condition for VRML output looks better, but I haven't tested it.
if (((getFieldOfView().length > 0) &&
!getFieldOfViewList().equals(FIELDOFVIEW_DEFAULT_VALUE)) ||
!ConfigurationProperties.getStripDefaultAttributes()) /* ArrayList .x3dv
compare */
{
stringClassicVRML.append("fieldOfView ").append("[
").append(MFFloat.toString(getFieldOfView())).append("
]").append("\n").append(indent).append(indentCharacter);
}
There's an ant target for just rebuilding one file, and building Jars, so I
can just modify OrthoViewpiont.java, that would be useful information:
I am not prepared to debug XSLT. But I see the comment you put there, so I
will go hunting.
I'm certainly hoping you will quickly upstream my code if I find a fix.
