Subject [jira] [Commented] (TUSCANY-3857) unwrapping OMElementWrapperHandler can't easily tolerate both non-valid data and minOccurs="0" data
Date Mon, 09 May 2011 22:08:03 GMT

    [ https://issues.apache.org/jira/browse/TUSCANY-3857?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13030925#comment-13030925

Scott Kurz commented on TUSCANY-3857:

One more note... I did take a quick look at the DOMWrapperHandler in implementing this, and
saw that this handler lacks a lot of the function of the AXIOM one.   Rather than open a vague
JIRA I'll try to find some time to follow up on the specific issues.

I wonder if it's worth factoring out some of the logic to a databinding-neutral place.. if
it's going to be this complicated.

>                 URL: https://issues.apache.org/jira/browse/TUSCANY-3857
>             Project: Tuscany
>          Issue Type: Bug
>          Components: Java SCA Axis Binding Extension, Java SCA Databinding-SDO
>            Reporter: Scott Kurz
>            Priority: Minor
> In r1086760, I committed a change to OMElementWrapperHandler.getChildren so that it could
handle unwrapping a wrapper with "missing" children, i.e. children with schema def of minOccurs="0"
which aren't present as a child of the wrapper.
> The code we had would, after not finding a child of given QName, group the wrapper children
into like-QName-elements and then allow indexing into this list of groups.  
> This would prevent the next wrapper child from matching normally in the minOccurs="0"
case, so I removed that logic.
> However, now I've broken our handling of schema-invalid payloads, as seen in the module:
> testing\itest\ws\endpoint-references
> Will have to think about how to handle both cases.
> I don't recall us talking about it in awhile, but I think the handling of XSD-invalid
data is a significant feature of Tuscany that we should try not to break.
