🚀 go-pugleaf

Thanks for the suggestion, which I tried. Unfortunately it's not working. 

Before changing the query string, I did this:

    HashMap saveqds = new HashMap();
    saveqds.put("SAVE", actualqds);

When wanting to revert to the original, I did this:

    actualqds = (QueryDataSet) saveqds.get("SAVE");

Having done this, the query string has not reverted and the row count 
remains 0.
