Suppress leading zeros

[kaiwa01]

How can a field be defined to suppress all leading zeroes? For example, the field should display as blank if it is set to 0000. I have tried using maskFormatter in the ui.xml and it causes 0000 to display as 0.

<fieldcontrol:Field label="{LABELS.extension}">
<formcontrol:TextInputField ui:field="extension_" width="100px" readOnly="true"
maskFormatter="####" />
</fieldcontrol:Field>

See DataSourceField.format. But note that whatever that XML syntax is that you're using, it's not what SmartClient and SmartGWT use.
