Integer variable getting set to 0 instead of null - Jsf 2.1, Weblogic

Question

I have a JSF 2.0 application on Weblogic 12c. I have a variable of Integer type in an Entity accepting input type="text" on the JSF side.

The issue is, on save, the Integer variable is getting set to 0 if the user does not enter any value in the field. I need it to be null. I searched for previous questions but only found answers for Tomcat which didnt work for me. How do I fix this?

private Integer code;

public Integer getCode() {
    return this.code;
}

public void setCode(Integer code ) {
    this.code = code ;
}

https://stackoverflow.com/questions/10282777/convert-empty-number-as-null - it seems the JSP Expression Language has an issue, and that could very well be that of apache. — Joop Eggen, Nov 29 '17 at 14:47
@JoopEggen but I use weblogic and so I cant add that VM argument. Can I? — Snehal, Nov 29 '17 at 15:38
It would not hurt. Try it (in a local weblogic). I have forgotten how to do it with weblogic. — Joop Eggen, Nov 29 '17 at 15:57

This might not answer why it is happening, but to 'fix' the issue you might try something similar to this:

public void setCode(Integer code ) {
    if (code == null || code.intValue() == 0) {
        this.code = null;
    }
    this.code = code;
}

This would only 'work' as a fix if you know your code value should never actually be 0.

Thanks but this is an issue all over the code so this is not a viable solution for me :( – Snehal Nov 29 '17 at 14:37
Ahh, too bad :(. Will let you know if I find an answer. – George Andrews Nov 29 '17 at 14:38
