How to update the List Box Field when its value has been changed with another callback function

fatcat1206

Hi All

I have created a "list box field" for a list of pin names, in a callback function of a form button, I have removed some items from the list, somehow the selection in the "list box field" does not change accordingly.

I check the value of "list box field", it has been changed, just the field itself has not been updated.

It's quite strange that when I assign the value of "list box field" in the CIW, the selection in the "list box field" dose change.

below is my callback fucntion, and "fPinInfoSel" is the listBoxField.

Does anyone knows where is wrong?

procedure(fFilterButtonCB(form)
let(
(
    DeSelPinKeyWordList           ;list of key words for deselected pin
    pinNameList                            ;an operation list
);local variable
    DeSelPinKeyWordList = parseString(SISpinInfoSelForm->fDeSelPinKeyWord->value)
    
    pinNameList = form->fPinInfoSel->value
    
    foreach(DeSelPinKeyWord DeSelPinKeyWordList
        foreach(pinName pinNameList
            when(rexMatchp(DeSelPinKeyWord pinName)
                remd(pinName pinNameList)
            );when
        );foreach pinName
    );foreach
    
    form->fPinInfoSel->value = pinNameList
    
);let
);proc

    Hi Sjoerd,

    That CCR is related to CDF callbacks being able to update the choices in a cyclic field. This thread is related to altering the selected values in list boxes in general forms (nothing to do with CDF and nothing to do with cyclic field choices). Even if it had been related to cyclic fields in an "hi" form, changing the choices there in a field callback is possible - it was just that the CDF callback mechanism didn't know how to cause the related form to be triggered to update the choices - so it was a CDF (and associated application that's using CDF) specific issue.

    Regards,

    Andrew.
