In the generated Editor after the table tree viewer i want added a 
StrcuteredTextEditor / TextEditor. Following is the snippet

// This is the page for the table tree viewer.

//

{

ViewerPane viewerPane =

new ViewerPane(getSite().getPage(), Ei2dEditor.this) {

@Override

public Viewer createViewer(Composite composite) {

return new TreeViewer(composite);

}

@Override

public void requestActivation() {

super.requestActivation();

setCurrentViewerPane(this);

}

};

viewerPane.createControl(getContainer());


treeViewerWithColumns = (TreeViewer)viewerPane.getViewer();


Tree tree = treeViewerWithColumns.getTree();

tree.setLayoutData(new FillLayout());

tree.setHeaderVisible(true);

tree.setLinesVisible(true);


TreeColumn objectColumn = new TreeColumn(tree, SWT.NONE);

objectColumn.setText(getString("_UI_ObjectColumn_label"));

objectColumn.setResizable(true);

objectColumn.setWidth(250);


TreeColumn selfColumn = new TreeColumn(tree, SWT.NONE);

selfColumn.setText(getString("_UI_SelfColumn_label"));

selfColumn.setResizable(true);

selfColumn.setWidth(200);


treeViewerWithColumns.setColumnProperties(new String [] {"a", "b"});

treeViewerWithColumns.setContentProvider(new 
AdapterFactoryContentProvider(adapterFactory));

treeViewerWithColumns.setLabelProvider(new 
AdapterFactoryLabelProvider(adapterFactory));


createContextMenuFor(treeViewerWithColumns);

int pageIndex = addPage(viewerPane.getControl());

setPageText(pageIndex, getString("_UI_TreeWithColumnsPage_label"));

}

/********************** This is the code i added in the generated editor 
****************************/


try {

StrunturedTextEditor editorsource = new StructuredTextEditor();

int textpageIndex = addPage(editorsource, getEditorInput());

setPageText(textpageIndex, editorsource.getTitle());

} catch (Exception ex) {

ex.printStackTrace();

}

***************************

I added the dependancies as stated in the multipage example . when i run the 
generated editor it throw following exception.
