The form is changed to the following.
Now pressing the <Enter> key and clicking the "Apply" button has the
same result - the button value is changed from "ack" to "all".
However, I expect that the button value should not change.
<form name="hwform" onsubmit="setgroup()">
<c:set var="unhwchk" value="" />
<c:if test="${ok}">
<c:set var="unhwchk" value="checked" />
</c:if>
<br><br><input type="checkbox" name="ok" id="ok" ${unhwchk}/>HW
<br>Rows Per Page<input type="text" name="rowsPerPage"
id="rowsPerPage" value="${rowsPerPage}"/>
<input type="submit" value="Apply"/><br>
</form>
