[OpenLayers-Dev] tinyows and OL WFS Filters using PropertyIsLike

[Paul Spencer]

Thanks Tim, that looks like a more thorough patch than the one I was  
envisioning - probably better that you did it :)  I will test soonish,  
I need to apply it to an older version of OL that I am using in a  
specific project but I had made essentially the same changes manually  
so I assume it will work.

Cheers

Paul
