Adobe Live cycle designer - Disable "highlight existing field", by default its enabled, also need to hide purple bar

Hi Experts,

Please help me with the below mentioned 2 issue.

Adobe Live cycle designer -

Point 1: Disable "highlight existing field", by default its enabled,

Code used:[but this is not working]

data::docReady - (JavaScript, client)

app.runtimeHighlight = false;

Point 2: need to hide purple bar

Code used:[but this is not working]

data::ready:form - (JavaScript, client)

event.target.viewState = {overViewMode:5}; // Hide all panes - This is even disabling the form's scroll bar also.

Thanks

Sajal
