I am trying to use a Dataset Memory tag inside a UDT to hold two columns of data. When I try to enter data into the dataset tag in an instance of the UDT, I am getting a dialog that says Error Saving Tag, Gateway Error 60001 when I try to Apply the changes to the dataset. Here is what I am seeing on the Gateway Console log:

[code]4:58:23 PM TagStore Error modifying tags

I am using Ignition v7.8.1 32bit running on Windows 7 Professional. I was able to update a dataset memory tag with similar data outside of a UDT. Any ideas why this would not work inside a UDT?

This is a known issue that was fixed in Ignition 7.8.2
