[x3d-public] 4 things before pursuing further development

[John Carlson]

John posted:
3.  Fix or remove alternate containerFields in X3DJSAIL.  /metadata/ alternate in MetadataSet.java.  Discussion of alternate containerField enumerations in X3DUOM.

Don replied:

Also reported on mailing list last week.  X3D3 and X3D4 containerField corrections relevant HAnimHumanoid/Metadata have been applied and deployed to the models in X3D Examples Humanoid Animation archives,*with most subsequent changes now deployed. *
Authors modify the name of a containerField to correctly show the field relationship to the parent.  You should never (i repeat Never Never Never) need to touch alternative containerField sources in underlying X3DJSAIL code.

I reply:

I was not trying to modify the alternative containerField sources.  I was responding to an exception thrown.  But I still need to search for the email in the mailing list.  In lieu of that, a more definitive exposition on how SimpleType has not been incorporated from X3DUOM with an subversion (SVN) commit will follow:

Here is relevant code about containerField_ALTERNATE_VALUES.  Previous emails discussed how the metadata containerField was included in X3DUOM for MetadataSet.java.  Here is relevant code from CreateX3dSceneAccessInterfaceJava.xslt. The first two sections of bolded, italicized, underlined text is where the two "value" container come in the containerField_ALTERNATE_VALUES String array.   What is missing from the array is what was intended to be done in the 3rd section of highlighted code.  That is, traverse into the <xsl:value-of select="InterfaceDefinition/containerField/@type"/> and pull out the SimpleType enumeration found in the @type value, instead a comment is provided (for later work?).  There's no xpath to skip to the enumeration yet.  I realize the code has not been released yet, and there is still existing code that provides a strawman way of doing it.  I was merely asking you to provide an <xsl:when> for MetadataSet which includes "metadata" as a workaround for not expanding the SimpleType (and maybe add "value" as well, but it will appear twice if you do that).  Imagine, perhaps, even replacing "value" with MetadataSet, since "value" appears in all cases with the default containerField, AFAIK.  I do not know if this is still a WIP, but not checked in state or not, since you hold stuff close to your chest.  If you say that this will be in the next release (which I think you have stated), I will be satisfied.  But don't say it's fixed.  It's not fixed until I can see the code working somewhere.  You need something better than that. There's an old story about devs that say they release right after a compile.

Now I will go look for the test case where having a metadata caused X3DJSAIL to throw an exception and I will retest.
