[OpenLayers-Users] How do I manually trigger permalink to update?

[Stephen Woodbridge]

How do I trigger permalink to update its paramaters?

I define my permalink like this:

             plink = new OpenLayers.Control.Permalink('permalink',null,
                 {'createParams': myCreateArgs});

and the function myCreateArgs() adds some additional parameters to the 
permalink. So when I change one of my parameters, how do I notify the 
premalink control that it needs to update the link.
