JSONResult - buildSMDObject method is never called internally
-------------------------------------------------------------
Key: WW-3694
URL: https://issues.apache.org/jira/browse/WW-3694
Project: Struts 2
Issue Type: Bug
Components: Plugin - JSON
Affects Versions: 2.2.3.1
Environment: Tomcat on windows, JDK1.5
Reporter: Alex Yavorskiy
Pre version 2.2.3.1 JSONResult object used to have a protected method that
allowed us to have a subclass that could modify URL of the SMD command being
sent in the response right before it was sent. That method was "writeSMD". In
version 2.2.3.1 of Struts there is no more method named "writeSMD", but there
appears to be equivalent protected method named "buildSMDObject". However, we
observed that buildSMDObject is never called by the infrastructure, so there is
no use overriding it.
After inspecting source for JSONResult, it looks like line 180 in the
readRootObject function is really intended to call buildSMDObject. However,
instead of calling the protected method in question, it creates SMD object
right there.
if (enableSMD) {
return new SMDGenerator(root, excludeProperties,
ignoreInterfaces).generate(invocation);
}
Fixing line 180 to call buildSMDObject should fix the issue. We had to
significantly re-write our subclass for JSONResult to work around the
deficiency. Hope this can be fixed in a future release.
