Ignition 7.6.2-rc-5

When I select more than one UDT, Edit tag(s), and then change a Data Type Parameter, only the Data Type Parameter of the first selected node is updated. I expected that the Data Type Parameter of all of the selected UDTs would be changed to the new value.

Currently there is no way to make changes to multiple UDT instances at the same time. You can see in the Data Type Structure area of the Tag Editor which UDT instance your changes will effect.
