beginner questions

hmm after all the time i tried to get rid of it i somehow started to like the header, so after removing it using jwrays hint it felt like there is something missing
so maybe i will keep it this time, but nice to know for future projekts!!

anyway: thanks a lot for your help guys!

That's funny, probably a reflection of the process the original developers went through.

But, you should have a better understanding of one way a Spring RCP application can be customized now, by the injection of none default implementations of various services.

sorry to bother you again, but i have another problem:
i got 2views, and i want the view to change when i hit a specific button

i tried to do this by just excecuting a viewTest command defined in my commands-context.xml

commands-context.xml

	<bean id="windowCommandManager"
		class="org.springframework.richclient.application.support.ApplicationWindowCommandManager">
		<property name="sharedCommandIds">
			<list>
				...
				<value>testCommand</value>
				...
			</list>
		</property>
	</bean>

and

<bean id="testCommand" class="org.springframework.richclient.command.support.ShowViewCommand">
		<property name="viewDescriptor" ref="testView" />
	</bean>

following the pdf-documentation i found in this forum i tried to get this command in the application with

ActionCommand test =(ActionCommand)Application.instance().getActiveWindow().getCommandManager().getCommand("testCommand");

and tried test.execute() to trigger the change view command


but it doesnt work, test.getActionCommand() returns null, why is that?

[jwray]

Not exactly sure as I've never used a command like that before (getting it explicitly from the command manager) but my guess is that since you haven't added the command to anything visual (menu bar etc) the action command does not exist,

Let's revisit. You are trying to have one command that toggles between two views, or two commands each responsible for activating its own view?

Let's assume the second. First off, you don't need shared commands. That's a more advanced concept in which a global command (eg save) can have its behavior changed depending on which view is active by defining an executor for that command.

Here's an example from one of my applications that sets up a menu of show view commands and adds it to the menuBar of an application, along with a couple of other menus.

<bean id="menuBar" 
		class="org.springframework.richclient.command.CommandGroupFactoryBean" >
	<property name="members">
		<list>
			<ref bean="fileMenu"/>
			<ref bean="viewMenu" />
			<ref bean="helpMenu"/>
		</list>
	</property>
</bean>

<bean id="viewMenu" 
        class="org.springframework.richclient.command.CommandGroupFactoryBean">
        <property name="members">
            <list>
                <bean class="org.springframework.richclient.command.support.ShowViewCommand" >
                    <property name="viewDescriptor" ref="testView" />
                </bean>
                <bean class="org.springframework.richclient.command.support.ShowViewCommand" >
                    <property name="viewDescriptor" ref="testView" />
                </bean>
                <bean class="org.springframework.richclient.command.support.ShowViewCommand" >
                    <property name="viewDescriptor" ref="testView" />
                </bean>
            </list>
     </property>
</bean>

The best place to look for this stuff is the example applications. They all have examples of how to configure commands and menus.

hi

thank you for your advice, but i already tried that: changing the view via menuBar works fine, but it doesnt solve my problem, i am still unable to do it in my class

i got a jtable in my first view, and if the user presses the "ok" button i check if there is really something selected in the table, and if so i execute the testView command.
i even tested xxx.execute(), it works perfectly for all commands defined in that class, so the real problem seems to be:

why does the commandManager return null instead of the command?

[jwray]

As I said, I've never used the commands the way you mentioned. I have only ever used them as attached and triggered to a user input.

So why isn't the command attached to the OK button? Or am I missing something?

Guess I'm still not sure what you are trying to do functionally.

*edit again*

ActionCommand x = (ActionCommand) getActiveWindow().getCommandManager().getCommand("testView");
x.execute();

i really dont know what i did wrong before, anyway, it works fine now

thanks for your help!
