Symptoms:

In your groov View project, if you assign an OPC UA tag as an input to a Computed Tag and the OPC UA is not assigned to a gadget or event in the project, the Computed Tag may lose the association with the OPC UA tag after restarting groov View.

Workaround:

For affected computed tags, add the related OPC UA tags to gadgets on a hidden page:

Create a new page in your groov View project and make sure to check Hidden in the Page Property panel.
Add the OPC UA tags to any type of gadgets on this new page.
Save your changes.

You can remove this page after you upgrade groov View to version 4.5e or higher.
