Re: Rules and custom property-level components (D2W)

hi all

A new day, a new idea.

To my question, I've the following solution:

I added a D2WContext as an attribute to my component. Additionally I  
created the corresponding getter and setter. In the constructor I  
took via the context the current component() From that object, I got  
the d2wContext by calling valueForKey("localContext"). So it looks  
like that:

		public class MyComponent extends D2WCustomComponent{

		  protected D2WContext d2wContext;

		  public MyComponent(WOContext context) {
		    WOComponent component = context().component();
		    D2WContext ct = (D2WContext)component.valueForKey("localContext");
		    setD2WContext(ct);
		  }
		
		  // Setter for the d2wContext
		  public void setD2WContext(D2WContext newD2WContext) {
                     d2wContext = newD2WContext;
		  }
		
		  // overwrites the method from D2WComponent
		  public D2WComponent d2wContext() {
		    return d2wContext;
		  }
		}
	}
That seems to work in my application. But is that also a good  
solution? Especially as regards "localContext" and the context 
().component() call, I'm not really sure if that's "allowed" or not.  
What do you think about it?
