When data is injected into Flexmonster in the form of a 2-Dimensional string with one column header and one entry below that column header, only the header is displayed in the Flexmonster grid. If another row entry in that column is added, then both entries appear. See attached .gif for details.
Thanks for reporting this issue to us!
It is already in a roadmap for the next minor release. The fix will be added on July the 2nd.
Let me know if you have any questions.
The version with the fix for the 2-Dimensional string has already been released. You are welcome to try it.
Waiting for the feedback from you.
