Extension element return value as variable

[Adam Jenkins <ma...@adamjenkins.net>]

Hi Everyone,

I have a custom extension element that returns a value (a spring context that stores a large cache of constants).  I enclosed it in a variable thinking the returned object would be set into the variable for use later however it’s storing an XRTreeFrag (the children themselves) into the VariableStack.

You’ll see what I’m trying to do below.  Does anyone have any idea of a better way to accomplish this?

Cheers
Adam

    public AbstractApplicationContext context(XSLProcessorContext context, ElemExtensionCall extensionElement){
       //returns the spring context
    }

}

public class MockElement {
	
	public void run(XSLProcessorContext context, ElemExtensionCall extensionElement) throws TransformerException {
	System.out.println("running");
        XPathContext xCtx = context.getTransformer().getXPathContext();    
        String selectExpressionString = null;
        boolean namespacePushed = false;
        boolean expressionPushed = false;
        try{   
            selectExpressionString = extensionElement.getAttribute("select");           
            XPath xpath = new XPath(selectExpressionString, xCtx.getSAXLocator(), extensionElement, XPath.SELECT);
            xCtx.pushNamespaceContext(extensionElement);            
            namespacePushed = true;
            int current = xCtx.getCurrentNode();
            xCtx.pushCurrentNodeAndExpression(current, current);        
            expressionPushed=true;
            Expression expr = xpath.getExpression();
            XObject result = expr.execute(xCtx);

	    //If I set the variable using select=“ “ I get back an XObject with the correct variable for “result"
            //if I set the variable using an extension element as above I get back an XRTreeFrag object
        }catch(Throwable t){
            t.printStackTrace();
        }
        finally
        {            
            if(namespacePushed) xCtx.popNamespaceContext();
            if(expressionPushed) xCtx.popCurrentNodeAndExpression();         
        }   
	}
