Programatically, reset a custom date field using ExpandoBridge

[darren rose, modificado hace 8 años.]

Hi,

Programatically, I need to reset/clear/set to null a custom field that is a date.

I am using the ExpandoBridge.

Any help welcomed, the errors I see when using null or empty string results in exceptions.

regards

layout.getExpandoBridge().setAttribute(String name, Serializable value, boolean secure)
ex: layout.getExpandoBridge().setAttribute("custom.value", "", false)

using "" results in

java.lang.RuntimeException: jodd.typeconverter.TypeConversionException: Unable to convert value: ; <--- java.lang.NumberFormatException: For input string: ""

Liferay uses millisecond value wrt(01/01/1970) for Date custom field. So you have to set its value as 0 instead "".

So,by setting it as 0, custom field value will be set as default date 01/01/1970.

Sure, but actually, my business case is to reset a date to null and not 1/1/1970 - which doesn't seem possible?
