ComboBoxItem - null as default value?

[Sindre]

My sql table allows null on the field witch i use a ComboBoxItem to alter.

The valuemap is like this:

		<field name="annulment_cause_id" type="enum" title="Årsak for tilbakekalling">
			<valueMap>
				<value ID="1">cause one</value>
				<value ID="2">cause two</value>
				<value ID="3">cause three</value>
				<value ID="4">cause four</value>
			</valueMap>
		</field>

When i manually backspace the field, the client sends null to server and the field is altered to null. All good so far.

But, when i try to do the same in code using myComboBox.clearValue() and then myForm.SaveVelues() nothing is sent to server! the field stays unaltered.

How can i do the same thing in code as i manually do by clearing the ComboBoxItem with backspace?

Use setValue(null) to set the value to null.

Use setValue(null) to set the value to null.

..Do not compile.

but this code solved my problem:

String value = null;
myComboBox.setValue(value);

Thanks a lot for quick reply!
