> Key: AXIOM-374
> URL: https://issues.apache.org/jira/browse/AXIOM-374
> Project: Axiom
> Issue Type: Bug
> Components: DOOM
> Affects Versions: 1.2.12
> Reporter: Andreas Veithen
> Assignee: Andreas Veithen
> Fix For: 1.2.14
>
>
> The createOMElement(String, OMNamespace), createOMElement(String,
> OMNamespace, OMContainer) and createOMElement(String, String, String) methods
> support auto-generating a namespace prefix (by passing a null prefix) and
> creating an element in the default namespace (by passing an empty string as
> prefix). This choice doesn't exist for the createOMElement(QName) and
> createOMElement(QName, OMContainer) methods because the prefix in a QName
> object can never be null. There is an inconsistency in the behavior of LLOM
> and DOOM when an empty prefix is passed in the QName object. LLOM will
> auto-generate a prefix, while DOOM will create an element in the default
> namespace.
> In the case of DOOM, this appears to be a bug because the corresponding
> createOMElement method contains the following condition:
> qname.getPrefix() != null
> However, the return value of QName#getPrefix() is never null, and the code
> that would auto-generate a prefix is unreachable.
> On the other hand, the desired behavior depends on the use case, and there
> are situations where one would like to create an element in the default
> namespace if the prefix in the QName is an empty string.
> Proposed solution:
> 1. Make sure that DOOM has the same behavior as LLOM, i.e. auto-generate a
> prefix if QName#getPrefix() returns an empty string.
> 2. Add additional methods to OMFactory that create an element from a QName,
> but that allow to specify the intended behavior.
