For others running into a similar problem. I've solved it as follows.

My markup contains:

  <div jwcid="block@Block">
    <a jwcid="link@DirectLink" listener="listener:showResult"  
updateComponents="result" async="true" parameters="ognl: 
{page.parameter}"><span jwcid="@Insert" value="ognl:page.linkText"/></a>
  </div>

At the place where I need to programmatically generate the link, I
call my page's setLinkText() method (which I added as an abstract
method) and similarly, setParameter(). Then I do

     Block block = (Block)this.getContainer().getComponent("block");
     block.renderForComponent(writer, cycle, this);

That worked for me.
