Panel with template renders null objects as null string

[sandeep45]

I have a panel with a template like this:

{
  xtype:'panel',
  tpl: 'first name is {fname}'
}

Now i update the panel and with null it actually shows the string null. This is not how it worked in sencha touch 1 and it should not say the string null.

I am updating like this:

panelObj.setData({fname:null});

Result is that I see this:

first name is null

What am i doing wrong

I'm actually going to open this as a bug.
