Devexpress MVC, JS error => Unable to process binding "displayNameExtender: function(){return { path:path,dataMember:value} }"

Error sample just of loading

Hello, im working with the asp.net MVC with the framework Devexpress (First image) I create a ReportDesigner and loads well but it appear this error when it finish to load,

2nd error

also at this second part, when I click with the mouse on outer parts of the report and then to the report just as the black ponds are drawed is giving me this message on the console "Uncaught TypeError: this._path is not a function" or "Uncaught TypeError: this._path is not a constructor" also happens every time when I select some items

I was identifying my problem and trying to fixing it

  • made it again but with different ways, one of them is based on this video => https://www.youtube.com/watch?v=0GSwNh1SRHg

  • I read the official documentation if there is some required or same issue and there isn't

  • Even I comment this script and still have the same issue

settings.ClientSideEvents.PreviewParametersSubmitted = "function (s,e){LoadingPanel.Hide();}";
settings.ClientSideEvents.PreviewDocumentReady = "function (s,e){LoadingPanel.Hide();}"; 
settings.DisableHttpHandlerValidation = true;
  • I debug the SaveCallbackRouteValues and it goes well.

  • on my JS is not mandatory to have script in there, so i didn't put some script in there yet.

  • I have try to fix it from the wizard the framework but still having the same problem.

----------------------------------------------------------------------------------------------

I am thinking that the problem is maybe my framework because of some libraries missing or bins or idk :(

Hope you can help me with this issue, Regards
