Ambigious use of isElementData in the Block interface
-----------------------------------------------------
Key: AXIS2-5023
URL: https://issues.apache.org/jira/browse/AXIS2-5023
Project: Axis2
Issue Type: Bug
Components: jaxws
Affects Versions: 1.7.0
Reporter: Ivan
In the Block interface, a method named isElementData is defined with doc
description below, from my understanding, it only return true while the block
could be represented as a single element.
/**
* @return true if data is always an element; false if possibly mixed
content or multiple
* elements
*/
public boolean isElementData();
In the getQName() of BlockImpl class, any XML parsing exception is swallowed
if isElementData return false. IMO, it should only ignore it while the block
elment might be a MIME type, which means it is of a DataSource type. e.g. while
invoking the Dispatch<Source>.invoke, aninvalid XML string like
<simplerequest><param>1</param><simpleRequest> is passed, no exception is
thrown, while a WebServiceException should be expected.
Thougths ? If I did not miss anything, would like to open a JIRA for it and
attach a draft patch.
