sap.ui.model.type.Date | formatOptions | XML

Hi,

I have a problem showing a Date in SAPUI5. I have this string "20140311102844".

I use this coding:

text="{

  path: 'GLB_HEAD_SCREEN>TimestampIns',

  type: 'sap.ui.model.type.Date',

  formatOptions: {source: {pattern: 'yyyy-MM-ddTHH:mm:ss'}, style: 'long'}}"

Somebody have an idea why it´s not working. Thanks!
