UIB - page refreshing continuously, events set up wrong? UIB help

[David Nendza]

Hello all, I am trying to use UIB to make a front end to do operations on an external system, and this front-end dev stuff really isn't my strong suit.  

I have the UI page set up with -

Input box, button

Contact card | contact card

repeater -> card container.

I need the user to input a username into the input box, then when the button is pressed it takes this user name and:

• queries the user table to check that it's valid and a user
• queries a remote table with the user name and pulls in the remote-specific user ID
• queries a 3rd table with that remote-specific ID to pull additional user information over.

I have this set up with multiple data resources.

The issue I'm encountering is that when testing the page, upon hitting the 'submit' button it gets the info and then 2 seconds later it refreshes the page and keeps doing that until all the data is gone from the page (I assume it's refreshing with 'null' as the input).  If I bring up the browser console I just keep getting a bunch of errors with one of them being - Uncaught TypeError: Cannot read properties of null (reading 'elm').

I have the data resources set up with 'when to evaluate this data resource' as 'only when invoked (explicit)'.  Events are set up like -

1. Input button: Button clicked -> REFRESH data resource (user lookup)
2. Data Resource (user lookup): data fetch succeeded -> (1) set loading state, (2) refresh my contact card data broker, (3) refresh the remote table user lookup data source
3. Data Resource (remote table user lookup data source): data fetch succeeded -> (1) refresh contact card data (this goes to a 2nd contact card), (2) refresh remote table additional info lookup data source, (3) set client param
4. Data Resource (remote table additional info lookup data source): data fetch succeeded -> set loading state (off).

Now, I obviously have something set up wrong because it's refreshing over and over.  What do I have to do if I want it to do nothing until the submit button is pushed, and then flow through the process once, instead of it refreshing over and over?  Do I need to use a different input?

Hi @David Nendza ,

Most probably event loop so one DR will refresh another DR, and they are triggering one another in loop. I would have to see the whole implementation to spot the problem. I would suggest creating 1 custom either transform or GraphQL data resource to query everything at once and get back data you need.
