Null pointer exception when using lfHideAllExcept on create screen

[Chris Rogers]

I am running into an issue when trying to use the lfHideAllExcept function when on the create screen.  The use case is that we want to show and hide relevant fields depending on a drop down value.

I am able to show or hide fields individually but get a null pointer exception (see below) when I try to use the lfHideAllExcept function with any field.  I'm relatively new to LiveFields so I'm sure it's something simple I'm missing but can't seem to figure it out

The initial script is pretty simple but the intent is to build out a list of all fields that are relevant for each option in the RFI Type field and show or hide them as appropriate...but I can't seem to get even a basic example to work.

Script:

if(argv["screen"] == "create"){
    if(argv["RFI Type"] == "Casings"){
        lfHideAllExcept("RFI Title");
		//lfHide("RFI Title");
    }
    
    else{
        lfShow("RFI Title");
    }
}

We fixed this in the latest version of JJUPIN (released). Do an update.

As always, have fun,

Radu

Thanks Radu, I can confirm this is working in 3.1.6

Hi,

you have probably error in the field name lfHideAllExcept("RFI Title");

check it. If you are sure that this is correct please use id of this custom field istead of name. It will work for sure. Any problem? let me know

[Chris Rogers]

Hi Michal,

Thank you for the quick response!  Unfortunately the results are the same regardless of whether I use the name of the field or the ID (and I get the same results if I use a JIRA default field like summary or description)
