I can not handle with 1 thing...
(In Bid please include GMap at the end of the bill to be sure You read all description and requirements!)
Problem is that xmlbuilder file as original get all values from data base (select *) instead of get values depending on Search results. I tried to modified that this xmlbuilder file get in session stored sql query and build xml - but xml is build (query works OK) but GoogleMap do not (!!!) build markers.
I suppose to GoogleMap marker builder java script need to change that it can read data from stored session or recreate other quick good working solution (now map is loaded on page load but need to work on document ready or whatever to work after data are filtered)!
