<input type="text" class="read-only" value="${FORM.dataAgendamento + FORM.horaAgendamento}" readonly="readonly" size="40"/>

If they are integers, it works perfectly, however for strings I'm getting java.lang.NumberFormatException:

I wanted to know how to do this concatenation of strings in the same input.

In case you tried to add two objects that are not numbers. Try the following:
