Javaflow can't call inherited methods
Summary: Javaflow can't call inherited methods
Product: Cocoon 2
Version: Current CVS 2.1
Platform: PC
OS/Version: Linux
Status: NEW
Severity: Normal
Priority: Other
Component: Flowscript
AssignedTo: dev@cocoon.apache.org
ReportedBy: Nikolaus@rath.org
A class named FlowHandler contains this method:
public void doInvokeMain()
{
try {
setParent(null);
doInvoke();
} catch (CommandException e) {
// Because we are the top level handler, something bad
// must have happened
throw new RuntimeException("Unhandled command: " +
e.getCommand());
}
}
MenuBarHandler is a class inherited from FlowHandler. The following does *not*
work (from sitemap.xmap):
<map:flow language="java">
<map:script src="org.rath.votra.MenuBarHandler"/>
</map:flow>
[...]
<map:match pattern="start">
<map:call function="invokeMain" />
</map:match>
When accessing the start URI, cocoon produces an InstantiationException.
When I add the doInvokeMain method directly to the MenuBarHandler class,
everything works fine:
/* If we do not define this method here, we get an
java.lang.InstantiationException
from cocoon. Seems to be a bug. */
public void doInvokeMain() {
super.doInvokeMain();
}
It seems that cocoon can't call inherited methods as flow handlers.
