Conversion Error Interceptor prevent errors for empty values
Can someone provide some clarification on if this interceptor should be adding a field error when an empty string is passed to a Integer in the action? I am trying to prevent the field error from happening in this case. It looks like it should not be happening according to the docs: https://struts.apache.org/core-developers/conversion-error-interceptor.html , or am I not understanding what it is saying here:
"This interceptor extends ConversionErrorInterceptor but only adds conversion errors from the ActionContext to the field errors of the action if the field value is not null, "", or {""} (a size 1 String array with only an empty String). See ConversionErrorInterceptor for more information, as well as the Type Conversion documentation"

Yasser,
Thanks for pointing me to the right class. After debugging, I found the problem was in my template and it was including the option body in the value when trying to set it to empty. There is no issue with the Interceptor and it is working as documented. Thanks for your help.

No you should check
`org.apache.struts2.interceptor.StrutsConversionErrorInterceptor`
(prefixed with `Struts`) instead. Could you put a break point on it's `shouldAddError` method and see what happens when you post auditForm.incorrectAuditReason.id?

I think you should define your stack including your new interceptor and ref it in your action definition.

Yes, I have it happening on 2.5.14.1. I have a select box pointing at a Integer like this: auditForm.incorrectAuditReason.id I am using the rest plugin which is including it in the stack. I have attached the source from Maven. Where is the check being done in the code? I see the check for shouldAddError() always returning true.
I have attempted to override the default interceptor by adding this in my package and overriding the shouldAddError(), but it continues to call the default Struts ConversionErrorInterceptor.

No, it should not be happening for `conversionError` interceptor. Does it happen?

You understood correctly. I reviewed it's code and looks like it should behave as above. Doesn't it?
I also saw `conversionError` is already included in default stack.
