List Widget error

[Tomellache2B]

Hello community

I am trying to get the output from my service to appear on my list widget.

I've pulled my service and "All Data" onto my mashup. However the widget gives me the error in the attachment below.

How do I go about fixing this ?

Your suggestions will be much appreciated thanks.

Hello,

is your output an infotable and is your service running successfully? (Ctrl+Alt+F9 --> Debug --> check "Services")

Please check if the DisplayField and the ValueField is defined under the WidgetProperties.

Best regards

Hi @M4RC 

Thank you for your suggestions,

Yes the output is an infotable with field: "Name".  Service works as desired: Takes an input (Name of a template), and outputs a list of the things within that template.

The DisplayField & ValueField properties of the list widget are set to: Name.  

Regards,

Hello, community.

I fixed the problem by using the "selection changed"  widget property and by binding this to my service. This way the service could pick up when a different value is being selected. (This value serves as input and comes from the button bar).
