Hi,
I have a OptionSet field on form and i wrote a code to hide a tab on this form if specific item is selected, But if no item is selected, I've got an Error:
function showtab (executionContext){
formContext = executionContext.getFormContext();
var Title = formContext.getAttribute('cos_joblevel').getSelectedOption().text;
if (Title != null){
if (Title == "Apprentice")
{
formContext.ui.tabs.get("tab_evaluationformapprentice").setVisible(true);
}
else
{
formContext.ui.tabs.get("tab_evaluationformapprentice").setVisible(false);
}
}
}
Can anybody help me with this problem?
Thank you in advance!

Hi,
If that item is not selected, `formContext.getAttribute('cos_joblevel').getSelectedOption()` will be null, and then calling `text` will cause the error you see, it is recommended to be like what `Mehdi El Amri` said First judge whether it is null.
If this helped you, I'd appreciate it if you'd mark this as a Verified Answer, which may in turn help others as well.
