dynamic a4j:support Problem

[fhagen]

Hi,

in my App i'm trying to build up a dynamic dataTable in which the inputfields should get some ajax4jsf support:

<rich:dataTable id="testTable" binding="#{positionBean.dataTable}" value="#{positionBean.positions}" var="pos" ajaxKeys="#{positionBean.rowSet}"/>

The whole binding without ajaxsupport works fine and everything is displayed.
But if i want to add the support i got an exception.
Here ist the "getDataTable" method:

public HtmlDataTable getDataTable() {
 HtmlColumn col1 = new HtmlColumn();
 UIOutput desc = new UIOutput();
 String test = "testdaten";
 Application app = FacesContext.getCurrentInstance().getApplication();

 ValueBinding vb= app.createValueBinding("#{pos.description}");
 desc.setValueBinding("value", vb);
 desc.setRendererType("javax.faces.Text");
 col1.getChildren().add(desc);
 dataTable.getChildren().add(col1);

 //2 columns
 for(int i=0;i<2;i++)
 {
 HtmlAjaxSupport supportClick = new HtmlAjaxSupport();
 HtmlAjaxSupport supportChange = new HtmlAjaxSupport();
 HtmlColumn col = new HtmlColumn();
 UIInput input = new UIInput();

 ValueBinding bind = app.createValueBinding("#{pos.output["+ i + "]}");
 ValueBinding bindStyle = app.createValueBinding("#{pos.style["+ i + "]}");
 MethodBinding onClick = app.createMethodBinding("#{pos.showFormula}",null);
 MethodBinding onChange = app.createMethodBinding("#{positionBean.calculateAction}",null);

 input.setId("pos" + i);
 input.setValueBinding("value", bind);
 input.setValueBinding("styleClass", bindStyle);
 input.getChildren().add(supportClick);
 //input.setRendererType("javax.faces.Text");

 supportChange.setEvent("onclick");
 supportChange.setReRender("pos" + i);
 supportChange.setFocus("pos" +i);
 supportChange.setAction(onClick);
 supportChange.setParent(input);

 col.getChildren().add(input);
 dataTable.getChildren().add(col);
 }

 return dataTable;
 }

If i remove the "supportChange.setParent(input);" line, the table is displayed but without ajax support.

Here ist the exception i receive:

How to bind the support correctly?

[fhagen]

Damn, i'm with stupid.

I found the error.

It seems to be important, that the support object gets his own id.
Unlike the definition of the rich:dataTable - component where the support - tag doesn't need an id is needed on the server side.

supportClick.setId("clickPosvalue");
supportClick.setEvent("onclick");
supportClick.setReRender("testForm:testTable");
supportClick.setFocus("posvalue");
supportClick.setAction(onClick);
supportClick.setParent(input);

The only thing which is still not running is the "setFocus" Part.
There I got a JavaScript Exception in Firefox.

focusElement.focus is not a function
