I am trying to bind a Menu object to a collection widget and am having some issues passing fields from the Menu's GetMenuItems service down to the mashup parameter of the sub-mashup.

 

Please see the images below:

Try using GetEffectiveMenu because potentially you are running into a permissions issue?

GetEffectiveMenu should show you what the user in actuality has available as menu items.

 

the getProperty from undefined seems to say that the entity is not visible.

I do not see you using this service though.

 

Also double check the datashape, I do believe 'title' lower case is correct, but perhaps in the datashape it is returning 'Title' instead. Not sure if title would be a 'reserved' word, you can always try changing the mashup parameter name to something like mashupTitle.

Tried with GetEffectiveMenu, same error. I am also running as an administrator, and can see the data being bound in the grid above. I can also see that there are multiple cells in the collection widget, showing that the data IS actually bound to the collection.

 

I did confirm in the datashape that title is lower case. I did try with "Title" and didn't have any success. 

 

Changed the param to mashupTitle and had the same error as well.

I also tried binding to a template.GetImplementingThings data source and have the same issue.
