Hello, I am encountering this error message whenever my script is executed. I have a data table that is bound to an array which will overwrite itself based of a user selection. The code successfully executes, and the table displays the new data the bound tag is overwritten with, so I don't not know why this is occurring. My script: ```auto window = system.nav.openWindow('zoneSelectDisplayData') zone2ItemsPath = '[default]reader0/antenna2StringArray' zone2TempA = system.tag.read(zone2ItemsPath).value tableItemsPath = '[default]whModelScreen/tableItems1' whichZonePath = '[default]whModelScreen/zoneSelected' system.tag.write(whichZonePath, "Zone 2") system.tag.write(tableItemsPath, zone2TempA) ``` Error: ```auto 15:52:58.328 [AWT-EventQueue-0] ERROR com.inductiveautomation.ignition.client.util.gui.ErrorUtil - Component name '[E2801191A5030062744B2254, E2801191A5030062744B22B4, E2801191A5030062744B22A4, E2801191A5030062744B2294, E2801191A5030063CDD78AB2, E2801191A5030063CDD78A92, E2801191A5030062744B2274, E2801191A5030063CDD78AC2]' is invalid, it is either non-unique, reserved, or has an illegal character. ``` Thanks, ---

Here it is. The tag the script is writing to is a string array. ```auto 15:52:58.328 [AWT-EventQueue-0] ERROR com.inductiveautomation.ignition.client.util.gui.ErrorUtil - Component name '[E2801191A5030062744B2254, E2801191A5030062744B22B4, E2801191A5030062744B22A4, E2801191A5030062744B2294, E2801191A5030063CDD78AB2, E2801191A5030063CDD78A92, E2801191A5030062744B2274, E2801191A5030063CDD78AC2]' is invalid, it is either non-unique, reserved, or has an illegal character. ``` ---

That particular error, involving the component name, smells like a java bug that afflicts users working through various flavors of Windows Remote Desktop, typically with terminals servers. Likely unrelated to the script itself. What version of Ignition is this? ---

Hmm. Maybe not that. You might want to open a support ticket and let them take a look. ---

Are you sure that's the _only_ script? Is it possible there's a _binding_ on some component's name to your array tag? ---

I have another script that is identical to the one posted. To handle the other selection. ---

The array tag itself is not bound to anything however there is a table that is bound to the array tag I'm overwriting. ---

This seems to also occur whenever I try to make a reference tag.
