MultiView Element help

I am trying to create my own custom "form" for Java Netbeans. Sort-of like
the swing GUI project templates that you can find in the Netbeans new file
window. I, so far, have been able to create and register a Java template to
the Netbeans new file prompt. Now I have ran into a problem. I cannot
figure out how to add a multi-view window to the template. I have been
trying to use the new file type to create it but it does not show up.

Sorry if this is confusing.
Here is an Example Representation of What I Have So-Far:

   1. MyExampleTemplate.java.template
   2. package-info.java
   3. MyExampleVisualElement.java

------------------------------

// Most of this is automatically generated by the Netbeans New File
Template. // I have Included These Files in the case they do not
generate the [email protected](...)@Messages(...)public
final class MyExampleVisualElement extends JPanel implements
MultiViewElement {
    private MyExampleDataObject obj;
    private JToolBar toolbar = new JToolBar();
    private transient MultiViewElementCallback callback;
    public MyExampleVisualElement(Lookup lkp) {//Is this good or do I
need to do somthing here to connect it?
        obj = lkp.lookup(MyExampleDataObject.class);
        assert obj != null;
        initComponents();
    }
    @Override public String getName() {return "MyExampleVisualElement";}
  //Warning as well as initComponents() Generated by Form.
    @Override public JComponent getVisualRepresentation() {return this;}
    @Override public JComponent getToolbarRepresentation() {return toolbar;}
    @Override public Action[] getActions() {return new Action[0];}
    @Override public Lookup getLookup() {return obj.getLookup();}
    //Overriden blank void methods excluded from example:
componentOpened, componentClosed, componentShowing, componentHidden,
componentActivated, componentDeactivated
    @Override public UndoRedo getUndoRedo() {return UndoRedo.NONE;}
    @Override public void
setMultiViewCallback(MultiViewElementCallback callback) {this.callback
= callback;}
    @Override public CloseOperationState canCloseElement() {return
CloseOperationState.STATE_OK;}}


   1. MyExampleDataObject.java

------------------------------

@Messages({ ... })@MIMEResolver.ExtensionRegistration( ...
)@DataObject.Registration( ... )@ActionReferences({ ... })public class
MyExampleDataObject extends MultiDataObject{
    public MyExampleDataObject(FileObject pf, MultiFileLoader loader)
throws DataObjectExistsException, IOException {
        super(pf, loader);
        registerEditor("application/my-meta-data+xml", true);
    }
    @Override protected int associateLookup() {return 1;}
    @MultiViewElement.Registration(...)
    @Messages(...)
    public static MultiViewEditorElement createEditor(Lookup lkp)
{return new MultiViewEditorElement(lkp);}}

After running I can create my object in Java however their is no
*'Visual'* button
on the bar. Only the *'Source'* and *'History'* Buttons show up.

Anyway I simply want to now the correct format required by Netbeans and its
OpenIDE as to how to utilize multi-windows. An example or a link to an
example would be fine.

I have tried looking at the Netbeans Documentation however I find it to be
confusing and unhelpful. I believe that the problem may be occurring do to
the fact that I am trying to add a template to an existing Netbeans
extension type(ex:.java, .xml, .exe). I have tried to look online howerever
I can only fine examples and tutorials for creating such items for new
unregistered extentions(ex: .mytag, .pasta, .fish, .abc).

Some sites I have looked at but did not help are, svn Multiview API Old
Tutorial
<https://svn.netbeans.org/svn/platform~platform-content/trunk/tutorials/67/nbm-multiview-api-old.html>,
and the Javadoc
<http://bits.netbeans.org/8.0/javadoc/org-netbeans-core-multiview/overview-summary.html>
.

To Duplicate:

   1. Create a Netbeans Module Project
      1. In the Netbeans IDE 8.2 go-to the New Project button → Select
*Netbeans
      Modules* → *Module* and then Click Next
      2. Should be a radio button Defaulted on 🔘*Standalone Module* → Next
      to the *Netbeans Platform* Label → *Development IDE* then enter in a
      name like 'NewFileExample' and Click Next
      3. Create a Code Name Base and Click Finish
   2. Insert a 16x16 picture ether in .gif or .png format into the file or
   somewhere accessible.
   3.

   Create a *'New File Type'*
   1. Make sure to be selected in your project's package where the Bundle
      object is located → Go to New File → Select *Module Development* →
      then *File Type* then Click Next
      2. type in a custom MIME Type such as *'text/x-mymime'*
      3. select the 🔘*by Filename Extension* radio button then → go to the
      text box next to the *Extension(s):* box.
      4. From here there are three different things i have overall tried.
      Choose one of the file extensions:
         - .java
         - .mycustomextention
         - .form
      5. Click Next
      6. Enter in a Class Prefix like *'ExampleFile'* then below select the
      image file that we got ready in Step 2. (Make sure that the ☑*Use
      Multiveiw* Checkbox is checked)
      7.

      check the generated files list below to match this:

      Created Files:
      - src/..*[file path]*../ [*MyClassPrefix*] DataObject.java
         - src/..*[file path]*../ [*MyClassPrefix*] Template.[*myextention*]
         - src/..*[file path]*../ [*MyClassPrefix*] VisualElement.form
         - src/..*[file path]*../ [*MyClassPrefix*] VisualElement.java
         - src/..*[file path]*../package-info.java *(unless already
         created)*
         - *[file path to image]*/ [*IconName*] .png

      Modified Files:
      - nbproject/project.xml
         - src/..*[file path]*../package-info.java *(unless not created
         yet)*
      8.

      Click Finish
      4.

   If you used the file Extention .java rename your template file extention
   to: .java.template and go into the package-info.java to change content =
   "MyClassPrefixTemplate.java" to content = "MyClassPrefixTemplate.java.
   template"
   5. Click run to run the code.

The Outcomes I got were:
- For .java a generated java file in the Others template with only
*'Source'* and *'History'*.
- For a custom extension like .mycustomextension a generated
mycustomextension file in the Others template with only *'Source'* and
*'History'*.
- For .form a generated .from file in the Others template with only
*'Source'* and *'History'* however if a generated form and javafile is
created the their will be other Bars that show up.

Sorry about if this is confusing.
thanks,
Merlin D.

also here is an added item to help clarify as an example :

I am trying to do something *like* this:

​[Note: this is just an example as well as the file still being .java with
some other extension (ex: .world ) that would function similarly to a .form]
