UI Builder: Repeaters bound to Client State Parameters don't refresh when the Parameter is updated

[Noah Boltik]

I have a repeater bound to a client state parameter "selected_projects", which is initially given a value of an array of length 1. The repeater is correctly showing 1 "row" of the contained components. I'm trying to update this client state parameter by using 'api.setState("selected_projects", ["blah", "test"]);'. This is working correctly, I validated that the client state parameter is being updated. However the repeater component doesn't seem to re-evaluate once the client state parameter updates, It will only ever show 1 row. Is there a way to manually tell a repeater component to refresh?

Troubleshooting steps I've taken so far: I've bound a client script to a button component such that when the button is pressed, an element is pushed to the "selected_projects" array. I added a log statement, and it is getting updated correctly: everytime I press the button, the length of the array increases. I then changed the "Data Array" property of the repeater to be scripted:

However, when I press the button component I added, the "Test" doesn't get logged. It is only logged when the page loads, not when the client state parameter is updated.

I have some bizarre issues that are similar to this. Firstly, I'm sending the start and end dates from a "Range Updated" event into a client state parameter. According to a script that logs these values to the console, they are correct at that point. However, by the time these values get to my data broker, they're different.

Also, I send the sys_id of a change to a different state parameter and it arrives (according to test script that logs it to console) but, after binding it to a display form only component, it just doesn't see it.

Somewhere between the client state and the thing I want to see the client state correctly, there is a mismatch and I have no idea where or what that could be!!
