NumberField Custom validation

[Kishore.buturi]

Hi,

I want to write a custom validator for NumberField by extending NumberFiled class.

My Requirement is I have to display in the numberfield as "(Multiple)" string even though it does not allow to insert string from JSON response object.

please can you help me in how to write a custom validation for NumberField to display string using extjs code whenevrer my numberfield containg the value as "(Multiple)" from JSON response object .

I would use TextField as basis and not NumberField (otherwise you also need to revert the maskRe).

Next, you need to override the validateValue and add your own validation.

I am a newbie in GWT/GXT world. I am trying to use a NumberField but I am getting ClassCastException.
BTW, I am binding the fields with a JSON object.

java.lang.ClassCastException

: java.lang.String cannot be cast to java.lang.Number
