Blank option on a variable

John Vo1 · ‎03-21-2019

Is there a reason why I have a blank option for one of my variable on this catalog item?

Is there something in my script that can cause this?

\

I also have Read Only as a choice under this variable.

Try this:

function onChange(control, oldValue, newValue, isLoading) {
	if (isLoading || newValue === '') {
		return;
	}
	var test = g_form.getValue('access_needed'); //Change accordingly
	
	g_form.clearOptions('type_of_access');
	
	if(test == 'flowcal mlp'){  //Change accordingly
		g_form.removeOption('type_of_access', 'read only');
        g_form.addOption('type_of_access', 'edit','Edit');
		
	}
	else
		{
        g_form.addOption('type_of_access', 'edit','Edit');
		g_form.addOption('type_of_access', 'read only', 'Read Only' );
	}
}

Not sure if that is fully the cause, but in your screenshot, you have a different case for "read only" in the remove option for read only vs. what the addOption says (which is Read Only). So maybe that's causing something?

	if (isLoading || newValue === '') {
		return;
	}
	var test = g_form.getValue('access_needed'); //Change accordingly
	
	g_form.clearOptions('access_needed');
	
	if(test == 'flowcal mlp'){  //Change accordingly
                g_form.addOption('type_of_access', 'edit');
		g_form.removeOption('type_of_access', 'read Only');
	}
	else
		{
                g_form.addOption('type_of_access', 'edit');
		g_form.addOption('type_of_access', 'read only');
	}
}
