I have a textfield, whose value is being provided by a local variable called local!state. And local!state is sometimes null which leads to crashing. So to prevent that I put the following for the textfield:
if(COMMON_IsNullOrEmpty(local!state),{}, { a!textField(label:"State", value: local!state, saveInto:local!state)})

but the textField seems to not like null values even after providing an if check statement. Can anybody help?...

Is COMMON_IsNullOrEmpty an Appian function? Or is it custom? I was able to get this working using the APN_isEmpty() function:

load(
local!state: "",
a!dashboardLayout(
firstColumnContents: {
if(COMMON_IsNullOrEmpty(local!state),{}, a!textField(label:"State", value: local!state, saveInto:local!state))
}
)
)
