Custom View returned from @Cmd

[Daren]

Hello,

I want to write a custom view for one of my record types and return
that view when a certain command is invoked. In preparation for this
development effort, I am trying to return a ListView to display all of
the records.

Here is the source of the command:

@Cmd
public static ListView ValidateRecords(CommandInfo cmdInfo) {

AbstractListEO invalidRecList =
getAllRecords(cmdInfo);
System.out.println("Creating SimpleListEO...");
return new ListView(invalidRecList);
}

The code for getting the records is equally simple:

public static AbstractListEO getAllRecords(CommandInfo cmdInfo) {
HBMPersistenceMechanism persistor =
getPersistor(cmdInfo);
AbstractListEO list = persistor.hql("from " +
Ns_BasicFieldVisit.class.getName() );
return list;
}

I see that some examples (Sympster, session + SessionView) use the
AlternateView mechanism to return a custom view, while others (Self,
space + spaceView) directly return a view in the command. Returning
the view in the command works best for me because I want the record
type to behave normally in all other cases.

Using the direct view return method, when I invoke the command I get
an exception that “Component creation must be done on the event
dispatch thread” (attached).

Any suggestions?
