Widget Js Cannot read property get of null

Hi All We recently converted our mendix project from 7.10.0 to 7.23.7 When completing a action from a microflow we receive the following error message. Cannot read property 'get' of null TypeError: Cannot read property 'get' of null     at E.<computed>.O.<anonymous> (http://localhost:8080/widgets/widgets.js?637069271698755888:19580:54)     at E.<computed>.O._getTargetObject (http://localhost:8080/widgets/widgets.js?637069271698755888:19608:17)     at E.<computed>.O.updateRendering (http://localhost:8080/widgets/widgets.js?637069271698755888:19577:22)     at E.<computed>.O.<anonymous> (http://localhost:8080/widgets/widgets.js?637069271698755888:19703:30)     at E.<computed>.O.<anonymous> (http://localhost:8080/mxclientsystem/mxui/mxui.js?637069271698755888:5:26619)     at E.<computed>.O._runSubscription (http://localhost:8080/mxclientsystem/mxui/mxui.js?637069271698755888:52:74956)     at E.<computed>.O.e.callback.e.val.n.callback (http://localhost:8080/mxclientsystem/mxui/mxui.js?637069271698755888:52:74289)     at Object.callback (http://localhost:8080/mxclientsystem/mxui/mxui.js?637069271698755888:79:27800)     at http://localhost:8080/mxclientsystem/mxui/mxui.js?637069271698755888:46:90859     at Array.map (<anonymous>) Anyone encountered the above issue before? Thanks in advance. Trishant Deva

That's odd, receiving a widget error in a microflow action. Which action? With what parameters? And always, or sometimes?

There apparently is a bug in one of your widgets. First, try the blunt way: do ‘Update all widgets’. But you probably already have.

Next, find out which widget is causing this by deleting them one by one. Start with the ones you suspect. Since Array.map starts this, probably it has to do with a list or Datagrid. Also the bad widget does a get on an object that it expect to have available, but has not found (hence: 'get’ of  null).



Hi Tim,

The error only occurs at when we perform a certain action.

We have updated all our widgets.

I suspect the widget that is bad widget is our formatNumber widget. We will try and delete all the widgets we suspect that are causing the error.

Thanks for the Help.
