[pdt-dev] BuildError when importing PHPStructuredEditor

[Robert Gründler <robert@xxxxxxxxxxx>]

Hi everyone,

i'm implementing a key-binding handler, which should switch between 
files that logically
belong together. However, when i try to get the ActiveEditor using the 
HandlerUtil and
cast it to a PHPStructuredEditor, i get the following build error:

The type org.eclipse.wst.sse.ui.StructuredTextEditor cannot be resolved. 
It is indirectly referenced from required .class files    
SwitchViewHandler.java

I've tryied to add the org.eclipse.wst.sse package to the dependencied 
(like in the php.ui project), but i still get the error.
The ui project has the following php dependencies:

org.eclipse.php.core
org.eclipse.php.ui

The code looks like this:

package com.dubture.cpdt.internal.handlers;

import org.eclipse.core.commands.AbstractHandler;
import org.eclipse.core.commands.ExecutionEvent;
import org.eclipse.core.commands.ExecutionException;
import org.eclipse.php.internal.ui.editor.PHPStructuredEditor;
import org.eclipse.ui.IEditorPart;
import org.eclipse.ui.handlers.HandlerUtil;

public class SwitchViewHandler extends AbstractHandler {

    @Override
    public Object execute(ExecutionEvent event) throws ExecutionException {

        IEditorPart editor = HandlerUtil.getActiveEditor(event);

        if (editor instanceof PHPStructuredEditor)
            PHPStructuredEditor pEditor = (PHPStructuredEditor)editor;

        return null;
    }
}

Any hints would be greatly appreciated.

thanks!
