Setting to null values for controls where visibility is false

Hi,

I met such a case 12 years ago and till now have to work with it.

Maybe it would be nice to have any 'form builder' checkbox but you can fix it now just by using 'simple' XPath expression. 

just in calculated field type something like:

if($myfiled = '1') then . else ''  ('' single quotes means empty string/value)

what will calculated as: if a field is visible ( $myfiled = '1' ) just accept what user typed, otherwise reset to empty value. 

And that's it :)

Hi Seth,

Yes, this would be very useful, and we do have request for enhancement #3152
for this (see link below). I've added a +1 from you!

Hi,

1. You can use the same formula in calculate as in visibility. 

2. Ok i forgot to add you need to explicitly mark field as readonly false() as Form Runner makes calculated fields readonly by default. Not sure what version you use but in 2018.2.1 (bug solved in the newer versions) you have to use dummy formula in readonly field like 1=2.

Hi Jarek and Alessandro,

Thank both of you for the quick and helpful responses.  I am using a multiselect option for the parent so the = option will not work unless I use a large matrix of all possible solutions containing the value(s) I need for the visibility.  I used this XPath for the visibility:

$MyField[contains(text(), '1')] or $MyField[contains(text(), '2')] or $MyField[contains(text(), '3')]

But I am not able to use the same formula in the calculated value?  I may not have the proper syntax. The second issue that is related is getting the formula to work with a dynamic dropdown.  When I have a formula like:

if($MyField[contains(text(), '1')]) then . else if($MyField[contains(text(), '2')]) then . else'' 

Then the dropdown becomes read only and the user cannot modify the dropdown.

I have tried many combinations but not one that has been a legal syntax or produced the results I am aiming to achieve.  Any thoughts?
