In https://cwiki.apache.org/confluence/display/OFBIZ/FAQ+-+Tips+-+Tricks+-+Cookbook+-+HowTo
some links to javascript and ajax e.g. in section "Ajax - Javascript - Json" "An easy way to get a data structure from server to Javascript in client browser" and "Integrate OFBiz with Yui-Ext" seem to be not valid anymore. Did the articles moved somewhere else? Is there any further documentation on javascript/ajax? I would like to choose a product-list in ecommerce via javascript/ajax and could not find an example for this. Thank you for help!
