Re: null on attribute setter

[Maarten Bosteels <mb...@gmail.com>]

I guess you can achieve this with a custom PrePostSet extension ?

Jacob Danner just posted a link to an interesting article:
http://www.ibm.com/developerworks/xml/library/x-xmlbeanse/?S_TACT=105AGX54&S_CMP=B0201&ca=dnw-904

Would it work to restore the oldValue when the newValue is null ?
Or even better: to return false from the postSet method ?

The postSet method returns void according to
http://wiki.apache.org/xmlbeans/PrePostSetFeature
but in the article it returns a boolean ?
