    <p>Do I need hidden buttons for each transition in Spring WebFlow2 on my form?</p> <p>I am starting to not like Spring WebFlow2 if this is true. Someone is telling me I need a hidden button for each transition I would like my form to have. Example If I have a form with a submit and reset I understand I should use two buttons.</p> <p>But if I have a form that needs to kick off a transition to load some data on the form do I really need a button for each transition type? I would found this crazy but is it true?</p> <p>He is my store. I have a form that the user starts to fill out and once the user clicks on a radio button I need to load a number of schools into a dropdown for the user to pick. The only way I found to do this is to use javascript and a hidden button to kick off the loadschool transition type. example:</p> <p></p> <p><strong>Is this the best way? Is this the only way? Do I really need a button for each transition?</strong></p> <p><strong>My Flow:</strong></p> <pre><code>&lt;view-state id="SchoolVisitReport" view="SchoolVisitReport.jsp" model="visit" &gt; &lt;transition on="submit" to="addVisit"&gt; &lt;evaluate expression="flowActions.validateVisit(visit, messageContext)"/&gt; &lt;/transition&gt; &lt;transition on="loadSchools" to="SchoolVisitReport" &gt; &lt;evaluate expression="flowActions.initializeSelectableSchool s(visit)" result="flowScope.selectableSchools"/&gt; &lt;/transition&gt; &lt;transition on="cancel" to="endState" bind="false"/&gt; &lt;/view-state&gt; </code></pre> <p><strong>My JavaScript:</strong></p> <pre><code>function loadSchools(strBorough) { alert("Loading Schools for borough " + strBorough); document.visit._eventId_loadSchools.click(); } </code></pre> <p><strong>My Radio Buttons:</strong></p> <pre><code>&lt;form:radiobutton tabIndex="9" onchange='loadSchools();' value="B" path="borough" /&gt;Bronx-X&lt;BR&gt; &lt;form:radiobutton tabIndex="10" onchange='loadSchools();' value="K" path="borough" /&gt;Kings-K&lt;BR&gt; &lt;form:radiobutton tabIndex="11" onchange='loadSchools();' value="M" path="borough" /&gt;Man.-M&lt;BR&gt; </code></pre> <p>So can someone please tell me if I am doing this the right and best way with webflow2.. thanks</p> <p>I tried the following code but the form does not get submited</p> <pre><code>&lt;script type="text/javascript"&gt; Spring.addDecoration(new Spring.AjaxEventDecoration({ elementId : "borough", formId : "visit", event : "onChange", params : { _eventId : "loadSchools", fragments : "body"} })); &lt;/script&gt; </code></pre>

    1. COyou need to put an id='borough1' id='borough2' id='borough3' in your radiobuttons if you want the last part to work, and either write the decoration for each of the radiobuttons or use a dojoquery to decore all 3 of them

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
