Thanks Dave,
In order to dispaly the error message if we give the whitespace infront of
the number , we need to set trim="false".
I sloved this problem by setting trim="false" for regex validation. Below is
the snippet.
Thanks a lot for you input.
<field name="caseNumber">
<field-validator type="requiredstring">
<message key="initializeCase.caseNumber.required"/>
</field-validator>
<field-validator type="regex">
false
[0-9]{1,}
<message key="invalid.fieldvalue.caseNumber"/>
</field-validator>
</field>
Regards
Siddiq.
