Set display only field from select list

I've started to learn APEX just recently.

I've a select list, called LB_TEST1, from which value I want to display in a display only field TB_TEST4

I've set up (inspired by this question):

  • LB_TEST1
    • select list (populated from a query)
    • action when value changed: None (default)
  • TB_TEST4
    • based on: page item value
  • also created a dynamic action:
    • when: LB1_TEST changes, no condition
    • action: set value
    • fire when result is true
    • set type: static assignment
    • value: &LB_TEST1
    • affected elements: TB_TEST4
  • (fields not listed mainly contain default values)

What happens:
each time I run application at first change of LB1_TEST's value TB_TEST4 is filled by the OLD(!) value of LB1_TEST.
subsequent changes of LB1_TEST are not triggering change of TB_TEST4

How can I fix this?

Modify your dynamic action as below,

  • Change set type from Static Assignment to JavaScript Expression
  • Change JavaScript Expression value from &LB_TEST1 to $v('LB1_TEST')

Also, look at how session state works in Oracle APEX. The link in the question you have referred above is a good start --> Doc Link
