I started out with the following code:
| <div class="input">
| <ui:repeat var="listvar"
value="#{NewBlogEntryComponent.blogEntry_be.tags}">
| <h:outputText value="#{listvar} "/>
| <h:commandButton value="Delete"
action="#{NewBlogEntryComponent.remove(listvar)}"/>
| <br />
| </ui:repeat>
| <br />
| <s:decorate>
| <h:selectOneMenu id="tags1" value="#{dev.nulll}"
onchange="submit()" valueChangeListener="#{NewBlogEntryComponent.listener}">
| <s:selectItems var="field" label="#{field.toString}"
value="#{AllTag}" noSelectionLabel="Please select : " />
| <s:convertEntity/>
| </h:selectOneMenu>
| </s:decorate>
| </div>
|
This is part of a larger form, where I'm letting the user fill an entity. The
depicted part is my stab at trying to input a list of references to other
entities. In the valuechangelistener I retrieve the selected entity directly
(thank you s:convertEntity!) and add it to the list. Works like charm, except
that when the onchange event occurs, the complete form is submitted (and thus
validated), whereas I'm only interested in updating the list. So, my next move
was to use Ajax4Jsf (since I'm not willing to extract this part into its own
separate form):
| .. skipped ui:repeat part, is the same ..
| <s:decorate>
| <h:selectOneMenu id="tags1" value="#{dev.nulll}">
| <s:selectItems var="field" label="#{field.toString}"
value="#{AllTag}" noSelectionLabel="Please select : " />
| <s:convertEntity/>
| <a:support event="onchange" reRender="relevantid"
bypassUpdates="true" action="#{NewBlogEntryComponent.listener(field)}"/>
| </h:selectOneMenu>
| </s:decorate>
|
However, the parameter I'm receiving in listener() is always null. How can I
access the selected value in the action method called by a:support? I guess
field is not really in scope anymore for the a:support tag, but what are my
options?
