Has anybody been successful in making the custom screens work on Chrome?

I have custom screens that make DME calls that work on IE - but fail on Chrome 50.x, Design Studio v10.x.

As far as I can tell, Chrome does not allow synchronous calls and a DME call makes a synchronous http call.

This is the message on the developer tools:

“Synchronous XMLHttpRequest on the main thread is deprecated because of its detrimental effects to the end user's experience. For more help, check https://xhr.spec.whatwg.org/”

Any ideas how to overcome this ?

Thanks.

I had to modify all my DME calls to work with Chrome and Firefox as follows:

//Construct DME string
sDME = portalWnd.DMEPath + "?PROD=" + strPDL
sDME += "&FILE=GLNAMES&INDEX=GLNSET1"
sDME += "&KEY=" + vCompany + "=" + vNewRetirementAcctUnit
sDME += "&FIELD=DESCRIPTION"
sDME += "&OUT=CSV&DELIM=~&NOHEADER=TRUE"

//Return value from table
var sReturn = portalWnd.httpRequest(sDME,null,null,"text/csv")

Thanks Terry. What do the two nulls do ?

They are required placeholders for the call that are not used. This was the solution given by Support/Development when I opened an incident with them. Made the changes, and it resolved my issues when using other browsers.

Here was their initial response:

"In the custom script, some of the server requests uses ActiveXObject("Msxml2.XMLHTTP") which is not supported on Chrome/Firefox. This is the one that causes the error. We can use portalWnd.httpRequest as a replacement for it and it is already being used on other function in the custom script."

I would like to hear more about any Chrome required modifications. I've been tasked to make our design studio forms work in both IE and Chrome and before October 31 ! Yikes

If the DMEs are different, can the same be anticipated for the AGS? Any additional information, or things to look for; would be greatly appreciated. I'm am just beginning to get familiar with Chrome's developers tool as well as becoming acquainted with the Infor OS platform, minus the IE development platform. So far, I've gotten a lot of spinning circles that I have narrowed down to lines that contain '.async', '.load' and '.loadXml'.
