[jira] Commented: (MYFACES-824) if submittedValue==null, required==true not checked

Simon Kitching commented on MYFACES-824:
----------------------------------------

I think that submittedValue will be null only if the submitted form did not contain that UIInput component at all.
In this case, validation is *not* required.

When the component is in the form, but has no value, I expect submittedValue is set to an empty string (not null).
See HtmlRendererUtils.decodeUIInput.

> In UIInput.java, in validate() at line 263 there is "if (submittedValue == null) return;"
> This seems to be incorrect to me.  If submittedValue is set to null, then validate returns without checking to see if required=true.  According to the UIInput spec javadocs " If the component wishes to indicate that no particular value was submitted, it can either do nothing, or set the submitted value to null."
