Programatically create a suggestion box with SetpropertyActi

[lucasmachado]

I am trying to programatically create a suggestion box with a nested setPropertyActionListener .

I already build richfaces from SVN so my code is with RF-923 already fixed.

The code above works fine in my app, so I dont believe is a implementation problem.

<h:inputText value="#{someCtrl.nome}" styleClass="txt" style="width:190px;" id="grupoNome" />


<rich:suggestionbox id="grupos" for="grupoNome" var="grupo" suggestionAction="#{someCtrl.nomes}" requestDelay="500" >
<h:column>
<h:outputText value="#{grupo.razaoSocial}" />
</h:column>

<a4j:support event="onselect" reRender="grupoNome" id="supportSetProperty">
<f:setPropertyActionListener target="#{someCtrl.idGrupo}" value="#{grupo.id}"/>
</a4j:support>
</rich:suggestionbox>

The problem is that i am trying to modify the component tree and create this components programatically on the fly.

// Create input text
String idInputRazaoSocial="pessoaJuridicaRazaoSocial";

HtmlInputText inputRazaoSocial = (HtmlInputText) context.getApplication().createComponent(HtmlInputText.COMPONENT_TYPE);
ValueExpression ve = context.getApplication().getExpressionFactory().createValueExpression(context.getELContext(), "#{ctrl.razaoSocial}",String.class);
inputRazaoSocial.setValueExpression("value", ve);
inputRazaoSocial.setId(idInputRazaoSocial);

panelGroup.getChildren().add(inputRazaoSocial);
inputRazaoSocial.setParent(panelGroup);

// Create suggestion box

HtmlSuggestionBox suggestionBox= (HtmlSuggestionBox) context.getApplication().createComponent(HtmlSuggestionBox.COMPONENT_TYPE);

suggestionBox.setFor(idInputRazaoSocial);

MethodBinding mb = context.getApplication().createMethodBinding("#{"+UIPessoaJuridicaComponent.CTRL_NAME+".ctrls['"+originalComponent.getClientId(context)+"'].autocompleteNome}",new Class[]{String.class});

suggestionBox.setSuggestionAction(mb);
suggestionBox.setVar("row");
suggestionBox.setRows(10);
suggestionBox.setWidth("300");
suggestionBox.setCellpadding("1");
suggestionBox.setId("suggestNome");

HtmlColumn column = (HtmlColumn) context.getApplication().createComponent(HtmlColumn.COMPONENT_TYPE);

suggestionBox.getChildren().add(column);
column.setParent(suggestionBox);

HtmlOutputText labelColumn = (HtmlOutputText) context.getApplication().createComponent(HtmlOutputText.COMPONENT_TYPE);
ValueExpression ve = context.getApplication().getExpressionFactory().createValueExpression(context.getELContext(),"#{row.razaoSocial}",String.class);
labelColumn.setValueExpression("value", ve);

column.getChildren().add(labelColumn);
labelColumn.setParent(column);


panelGroup.getChildren().add(suggestionBox);
suggestionBox.setParent(panelGroup);

// Done creating suggestion box
// Creating HtmlAjaxSupport

HtmlAjaxSupport a4jSupportComponent = (HtmlAjaxSupport)context.getApplication()
 .createComponent(HtmlAjaxSupport.COMPONENT_TYPE);
a4jSupportComponent.setEvent("onselect");
a4jSupportComponent.setReRender(otherComponentId);
a4jSupportComponent.setId(support_razaoSocial");

ValueExpression target = context.getApplication().getExpressionFactory().createValueExpression(context.getELContext(), "#{ctrl.id}", Long.class);

ValueExpression propertyValue = context.getApplication().getExpressionFactory().createValueExpression(context.getELContext(),"#{row.id}", Long.class);

SetPropertyActionListenerImpl listener = new SetPropertyActionListenerImpl(target,propertyValue);
a4jSupportComponent.addActionListener(listener);

suggestionBox.getChildren().add(a4jSupportComponent);
a4jSupportComponent.setParent(suggestionBox);

The code renders fine, the suggestion box works but the ajaxsupport doesn't rerender or calls the setPropertyActionListener

I have noted that when the component tree is generated by xhtml the HtmlAjaxSupport component isn't on the children list of htmlSuggestion, because of that i am suspecting that the problem is in how I add the HtmlAjaxSupport component on the tree.

Any ideas about how to make this work?

I found the solution


HtmlAjaxSupport participates on the component tree as a facet. So the correct way to add it on a suggestion box is:

String facetName = AjaxSupportTag.AJAX_SUPPORT_FACET+"onselect";
 suggestionBox.getFacets().put(facetName, a4jSupportComponent);

Thks.
Probably this post will be better on Ajax4JSf user forum. I could not move it. Sorry

You're right on your way, a4j:support is actually stored in facet.
Feel free to post in RichFaces users forum - since RF merged with A4J, there's no difference between those libraries. A4J forum is posted to by users of older versions of ajax4jsf.
