add button in show.jspx in a spring roo mvc project -

i've created spring roo project using 'getting started spring roo' starting point. project created in sts using roo 1.1.5. i've added neo4j graph , able create nodes simple edges , create web-part issuing 'controller --package ~.web'.

the project simple web-app person , race node , participant-edge start-time, end-time, total-time , race-id. since edge participant @relatedtovia becomes @relationshipentity , want add button save participant.

i found web-inf/tags/form/field/table.tagx add-, modify-, delete-buttons , friends defined, ie.:

      <c:if test="${update}">         <td class="utilbox"> 

..

but set variable update? i've looked through code created sts, unable find it. pardon if obvious.

regards claus

edit:

i found out web-inf/tags/form/show.tagx have knobs enable/disable instance update-button:

<c:if test="${empty update}">   <c:set var="update" value="true" /> </c:if> 

so add new button in file. spring framework seems laid out. have find various places.

regards claus

the value update obtained attributes specify when use tag created using tagx.

for example,

if form:table used in jspx , if following set, recieve true in update variable if assigned using directive. seems true set default in form:table tag within spring roo.

if want set false, when using have set value attribute following.

<form:table update="false" />

if want go deeper this, in table.tagx file have mentioned find following line explains it.

<jsp:directive.attribute name="update" type="java.lang.boolean" required="false" rtexprvalue="true" description="include 'update' link table (default true)" />

cheers.
