Formloader in Mx 5.16.1 - Browser console error

[stephanbruijnis]

Hi Andries,

I read your comments on https://mxforum.mendix.com/questions/5813/FormLoader-for-Mendix-5, but I still have an issue with the formloader.

I've tried the various versions:
The company 'Flock of Birds' developed a version fox Mx5, If Mendix permits I post it on GitHub too. https://www.dropbox.com/s/dht3kjr5ol9jjy0/FormLoader.mpk
This generates an error in the browser console, and doesn't show the data.
mendix.sys.Data.get: error in handler for [50665495807919181] : FormLoader_widget_FormLoader_1.applyContext: TypeError: ioBind.addErrback is not a function

Newer version of mx 5 uses other version of dojo: https://www.dropbox.com/s/5nquoyleueos4s1/FormLoader.mpk
Generates several errors in the browser console, and prevents the application from actually finishing loading
mendix.sys.Data.get: error in handler for [1125899906844025] : mxui_widget_DataView_12.applyContext: Error: mxui_widget_DataView_13.applyContext: Error: mxui_widget_TabContainer_0.applyContext: Error: mxui_widget_TabContent_2.applyContext: Error: mxui_widget_DataView_15.applyContext: Error: mxui_widget_DataView_16.applyContext: Error: FormLoader_widget_FormLoader_0.applyContext: TypeError: Cannot read property 'mixin' of null
and
An error occurred while handling queued requests Error: FormLoader_widget_FormLoader_0.applyContext: TypeError: Cannot read property 'mixin' of null(…)
and
mendix.sys.Data.get: error in handler for [12103423998559609] : mxui_widget_TabContainer_0.applyContext: Error: mxui_widget_TabContent_2.applyContext: Error: mxui_widget_DataView_15.applyContext: Error: mxui_widget_DataView_16.applyContext: Error: FormLoader_widget_FormLoader_0.applyContext: TypeError: Cannot read property 'mixin' of null
and
mendix.sys.Data.get: error in handler for [50665495807919281] : FormLoader_widget_FormLoader_0.applyContext: TypeError: Cannot read property 'mixin' of null

And finally I tried the latest version from this Github (used the MPK in the Formloader-master\test\mx517\widgets folder). Which gave me the same errors as the one above:
mendix.sys.Data.get: error in handler for [1125899906844126] : mxui_widget_DataView_45.applyContext: Error: mxui_widget_DataView_46.applyContext: Error: mxui_widget_TabContainer_1.applyContext: Error: mxui_widget_TabContent_5.applyContext: Error: mxui_widget_DataView_48.applyContext: Error: mxui_widget_DataView_49.applyContext: Error: FormLoader_widget_FormLoader_1.applyContext: TypeError: Cannot read property 'mixin' of null
and
An error occurred while handling queued requests Error: FormLoader_widget_FormLoader_1.applyContext: TypeError: Cannot read property 'mixin' of null(…)
etc..

The Flock of Birds seems to have the least issues , but still doesn't show data and one error in the console. The other versions block the application (keeps loading) and generate a lot more errors in the browser console. Could help me with this? Any idea what could cause this problem?

The FormLoader is positioned in:
A data view which listens to a data grid.
The data view also has a Microflow Timer, this microflow timer creates objects used in the dataviews in the FormLoader.

With kind regards,
Stephan

I'm experiencing the same issue as Stephan, sometimes I get an error in the console:
mxui.js?635989271334185496:29 mendix.sys.Data.get: error in error handler for xpath //TimeRegistration.RegistrationRecords[TimeRegistration.RegistrationRecords_RegistrationWeek="24769797950538032"][TimeRegistration.RegistrationRecords_Employee = '[%CurrentUser%]'] : mxui_widget_DataView_32.applyContext: Error: FormLoader_widget_FormLoader_6.applyContext: TypeError: ioBind.addErrback is not a function (webcore.datasource.XPathSource)

I'm using this widget to avoid the limitation of not being able to edit values in a template grid using a snippet.
