We have a autocomplete control sourced from a data page & a search icon/button to open the corresponding assignment for the entered value. On the open assignment action we have a when condition to check if the assignment key is null or not, if the key is null the action should not be performed.
Sometimes the when condition is always false and cases with valid assignments are not opening & at times the condition is always true.

I think you need to change the OnChange action from post value to refresh section (which has the action button). When conditions are launched on screen (section) load, so if you change the text field, the action generated on load is still the same. Please try with section refresh.
