hiCreateCyclicField : Value changes when the choices are updated

kkdesbois

Hello,
When I update the list of choices of a cyclic, the selected value is updated to the first value of the nex choices list, even if the selected value is still part of the new choices list.

Is there a way to avoid that?

Code example :

trCyclicList = '("1" "2" "3" "4" "5" "6" "7" "8" "9" "10")
trCyclicField = hiCreateCyclicField(?name 'trCyclicField ?prompt "Cycle Through: " ?choices trCyclicList ?value "3" ?defValue "7" ?callback "println" )
hiCreateAppForm( ?name 'trSampleForm2 ?formTitle "Sample Form" ?callback "println( 'FormAction )" ?fields list(trCyclicField) ?unmapAfterCB t )
hiDisplayForm(trSampleForm2)

If I modify the choices list from the CIW : 
trSampleForm2->trCyclicField->choices='("1" "2" "3" "4" "5" "6" "7")

  • Laurent,

    I can't find any requests or default mean to change this behaviour, but if you do:

    let(((curVal trSampleForm2->trCyclicField->value)) trSampleForm2->trCyclicField->choices='("1" "2" "3" "4" "5" "6" "7") trSampleForm2->trCyclicField->value=curVal)

    then it will preserve the current value. You could always make it a bit safer (to avoid a warning if the current value didn't exist):

    let(((curVal trSampleForm2->trCyclicField->value)) trSampleForm2->trCyclicField->choices='("1" "2" "3" "4" "5" "6" "7")
      when(member(curVal trSampleForm2->trCyclicField->choices)
        trSampleForm2->trCyclicField->value=curVal
      )
    )

    Of course, you could wrap this up in a convenient function to change an selectively preserve current values on choice changes.
