hi,
i used validations in Struts 2 using <validators> im facing problem with the 'Integer' type value here is the code

if i run the application..
1) if i leave 'Width' textbox empty it is showing 'Width is required' it is working fine
2) if i enter string values i.e., 'abc' is should not take and populate the error as 'Width is number'...but im getting as 'Width is required'
Can any one help me out...in this

This topic seems to say that the conversion of the field to a number fails silently if the value is not an number, so it may pass on an null/empty value to the validator, which would cause the behaviour you are seeing.
