Description Ian Bull CLA 2007-09-18 17:22:58 EDT 
Zest connections styles should be changeable after the connections have been created.  Opening to investigate.

Actually, there is an explicit condition on AbstractStructuredGraphViewer, if there is an input, a error is thrown. 
If i just comment the line, nothing else is affected, the graph viewer works perfectly fine and the connection style is really changed, it just works.

public void setConnectionStyle(int connectionStyle) {
		if (getInput() != null) {
		 //ZestException.throwError(ZestException.ERROR_CANNOT_SET_STYLE, "", null);
		}
		if (!ZestStyles.validateConnectionStyle(connectionStyle)) {
			ZestException.throwError(ZestException.ERROR_INVALID_STYLE, "", null);
		}
		this.connectionStyle = connectionStyle;
	}

Why exactly one cannot set the style after the graph is already set?
