Back and Forth Data display in Thingworx

[TIRUNL]

Hi All,

Can someone please help me in achieving back and forth data display in thingworx without using session variables.

Detail Requirement.

I have back and forth button in my mashup and need to update the info-table content based on the back and forth button clicked.Also index is to be displayed as shown in attached image.

Attaching screen shot of display for reference.

Appreciate quick help.

Thanks in Advance

Session variables would of course be the simplest way, however there could be two other possibilities. 

One is to use a service to store the value on the platform (in an infotable property on some thing or on the user extension).  Pass in the current infotable and new values and it can combine them and return the new infotable.

Second would be a custom widget extension that includes the infotable as a property and accepts a new infotable that would append the values.

Thanks,
Adam
