Did the OpenURL change

I had a view filter working 2 weeks ago and it stopped working. Did the OpenURL function change?

I have my openURL using the format shown in the sample code in the creating dynamic views example in help

openUrl((((((("/" + zoho.adminuser) + "/") + zoho.appname) + "/html/Repair_Detail_view/Customer_Contact=") + input.Contact_Number) + "&Repair_Tag=") + input.Repair_Tag, "new window");

That stopped filtering records for me. I would get all records.

I changed my openurl format to the version I found in the forms tonight and the filter works.

openUrl("#View:Lesson_Plan_view?State=" + input.State + "&Topic=" + input.Topic, "same window");

Am I dreaming or did something change?
