g_form.getOption() doesn't work in Workspace - need an alterative

[Marc D]

Hello everyone. My current project has a requirement - when Category is set to a certain value, it adds an extra option to the Subcategory choices. To do this, I created a UI Policy with scripts like these:

Execute if true:

function onCondition() {

    if (!g_form.getOption('subcategory', 9)) {

        g_form.addOption('subcategory', 9, '<insert some name here>');

    }

}

Execute if false:

function onCondition() {

    g_form.removeOption('subcategory', 9);

}

This worked fine at first, but we later discovered that it didn't work when testing in the Workspace. After looking it up, I discovered that g_form.getOption() doesn't work in Workspace. Are there any alternatives I can use? I was using getOption() specifically to check to see if the extra Subcategory choice already existed.

Hello, subhamdubey.

I did see that article earlier, but it does not seem like it would work for my use case. The algorithm I am trying to use is:
Does option <x> already exist?
If yes, do nothing

If no, add option <x>

The getDisplayValue() function appears to only get the currently selected option - it needs to be able to check on existing options without selecting one. If that's NOT how getDisplayValue works, please explain what it would do in this situation.

Hi @Marc D 

Is your subcategory field dependent on category field ? If yes, then you can't add options to subcategory field. Can you please confirm on this to debug it further ?

Hello, Amit.
In this specific implementation, the Subcategory field is NOT dependent on the Category field. The addOption and removeOption functions work fine - it's the getOption function that doesn't work properly. I COULD remove the checking for duplicates, but then I risk having duplicates.
