Connector Problems since 4.1 and ASP.NET connector

Since 4.1 you add to prevent caching in some browsers extra param like “dhxr0123456789”.
When you use ASP-Connector you will have a request like:

_http://localhost:23210/HAIZHandler/clsPackageList.ashx?connector=true&dhx_colls=2,8,9,10,11,12,13,14,15,16&dhxr1417520682746

This will end up in a error:
System.NullReferenceException: Object reference not set to an instance of an object :confused: wtf???

After a short investigation it turns out that there is a missing = in the line above:

_http://localhost:23210/HAIZHandler/clsPackageList.ashx?connector=true&dhx_colls=2,8,9,10,11,12,13,14,15,16&dhxr[b]=[/b]1417520682746

So i changed in the dhtmlx.js all places from “dhxr” to “dhxr=”

old: “mode=html5&dhxr” + new Date().getTime()
new: “mode=html5&dhxr=” + new Date().getTime()

From now all works fine :smiley:

kind regards

Thanks for info.
We will update the master codebase accordingly.

This extra dhxr parameter also will not work on my apache web servers. Apache see the url and because it’s missing the equal sign it throws 400 bad request.
