Error in

[rdawes]

Hi folks,

I am getting the following exception when using TableFormBuilder to create a form.

Here is my code:

public class ConversationForm extends AbstractForm {

	public ConversationForm(FormModel model) {
		super(model, "ConversationForm");
	}

	@Override
	protected JComponent createFormControl() {
		TableFormBuilder formBuilder = new TableFormBuilder(getBindingFactory());

		formBuilder.add("requestMethod");
		formBuilder.add("requestUrl");
		formBuilder.add("requestVersion");
		formBuilder.row();
		formBuilder.add("requestContent");
		formBuilder.row();
		formBuilder.add("responseVersion");
		formBuilder.add("responseStatus");
		formBuilder.add("responseMessage");
		formBuilder.row();
		formBuilder.add("responseContent");
		return formBuilder.getForm();
	}
}

java.lang.NullPointerException

The null pointer seems to be that the value that is being passed to the HashTable is null (not the key). As best I can judge, this is related to the undoCommand globalID. I have tried to debug this, but I have been unsuccessful so far.

Does anyone have any ideas?

Thanks,

The error seems to be the null when creating the TargetableActionCommand in the following code in TextComponentPopup.java:

    protected CommandManager getCommandManager() {
        CommandManager commandManager;
        ApplicationWindow appWindow = Application.instance().getActiveWindow();
        if (appWindow == null || appWindow.getCommandManager() == null) {
            if (localCommandManager == null) {
                localCommandManager = new DefaultCommandManager();
            }
            commandManager = localCommandManager;
        }
        else {
            commandManager = appWindow.getCommandManager();
        }
        for (int i = 0; i < COMMANDS.length; i++) {
            if (!commandManager.containsActionCommand(COMMANDS[i])) {
                commandManager.registerCommand(new TargetableActionCommand(COMMANDS[i], null));
            }
        }
        return commandManager;
    }

It is then immediately used to register keyboard shortcuts, and since it is null, we throw an exception.

add the red text in your <application-context>.xml, the hot keys of the commands will be taken out from the messages_xx.properties

Thanks for the suggestion.

I already had that in my application context, along with a reference to my own messages.properties file as well.

I can't remember now, but I think I worked around this problem by making sure that the cut and paste global commands were always defined in the commands.context file (I didn't think I needed them since I would not be using them for my own purposes other than the usual copy and paste in text fields)

I have exactly the same problem
Can anyone please give instructions what to do?

[bambala2002]

OK, I got it. Don't use the Eclipse XML formatter on the richclient-application-context.xml

It inserted some spaces,
so instead of

<value>org.springframework.richclient.application.messages</value>

i had

<value>
      org.springframework.richclient.application.messages
</value>

This messed things up. The labels weren't working, the hot keys...


So, who's fault was it anyway? Mine, eclipse or Spring? Should Spring parse its XMLs better?
