There’s an eagerly loaded screen with data being filled by workflow method. There’s an action button that opens a modal dialog and upon return the main screen data is refreshed. But after the refresh the button is not available anymore and user has to reopen the screen.
I found a work around. If the user switches to a different screen and comes back, the action button becomes available.
The problem wasn’t present in the build 2021.1.0.2221. I suspect Fix reloading rowstates flicker by ptomask · Pull Request #224 · origam/origam-html · GitHub to be a reason for this issue.
