Question

I’ve got a factory class that creates input windows on-the-fly for me. The reason for the creation of this factory class is to simplify the creation of input windows, as I have a lot of them. We are currently porting our app to android from iOS, and that’s when we discovered this problem.

I’m trying the create a textfield like so:

  textField = Ti.UI.createTextField
    left: indentLeft
    right: 10
    color: "#336699"
    borderStyle: Ti.UI.INPUT_BORDERSTYLE_NONE
    field: field
    hintText: field.hint
    value: field.value
    tag: field.name
    autocorrect: field.autocorrect
    autocapitalization: field.autocapitalization
    enabled: (field.enabled != false)
    keyboardType: field.keyboardType
    passwordMask: field.passwordMask
    returnKeyType: Ti.UI.RETURNKEY_DEFAULT
    textAlign: field.textAlign

This works perfectly fine on iOS, and the values specified by field.keyboardType and field.passwordMask are perfectly legal values according to the titianium docs. However, my android app crashes unless i comment out passwordMask AND keyboardType… Any idea why this would happen? Heres the android crashlog:

the above error indicates that in TiConvert.java class at line 342 you are trying to convert a null value to boolean check it.
