Good day.

 

I think I found a little bug in last version of JSF RI.

 

I use f:param inside commandLink. It's attribute "name" is required. I set
name, but don't set attribute value. This way I have an exception:

 

java.lang.NullPointerException

If I set value, for example, "1", everything is good.

There is an error in the following code:

 

        for (Param param : params) {

            sb.append(',');

            sb.append(param.name.replace("'", "\\\'"));

            sb.append(',');

            sb.append(param.value.replace("'", "\\\'"));

        }

 

Attribute value is not necessary, but it is used here as necessary.
