UICommandLink inside HtmlColumn don´t call bean method.

[danilocps]

Hi all.

I am experiencing a problem with the dynamic components UICommandLink inside the HtmlColumn component.

I created a datatable:

Application app = FacesContext.getCurrentInstance().getApplication();
HtmlDataTable dataTable = (HtmlDataTable) app.createComponent(HtmlDataTable.COMPONENT_TYPE);
dataTable.setValue(someDataModel);
dataTable.setVar("item");

HtmlColumn col = (HtmlColumn) app.createComponent(HtmlColumn.COMPONENT_TYPE);
UIOutput out = (UIOutput) app.createComponent(UIOutput.COMPONENT_TYPE);
out.setValue("col title");
col.getFacets().put("header", out);

UICommandLink link = (UICommandLink) app.createComponent(UICommandLink.COMPONENT_TYPE);
link.setExecute("@this");
link.setValue("click here");

ExpressionFactory expf = FacesContext.getCurrentInstance().getApplication().getExpressionFactory();
MethodExpression exp = expf.createMethodExpression(ctx.getELContext(), "#{myBean.actionLink}"
                , null, new Class[] {});
link.setActionExpression(exp);

col.getChildren().add(link);
dataTable.getChildren().add(col);

The method actionLink in myBean is not called.

But if I put the UICommandLink outside the dataTable works.  Or if I put the UICommandLink in (header of HtmlColumn):

col.setHeader(link);

Works fine.

The problem is when the UICommandLink inside the HtmlColumn component (as children).

To solve temporarily this problem, my commandLink call a jsFunction:

UICommandLink link = (UICommandLink) app.createComponent(UICommandLink.COMPONENT_TYPE);
link.setExecute("@none");
link.setValue("click here");

ExpressionFactory expf = FacesContext.getCurrentInstance().getApplication().getExpressionFactory();
ValueExpression vexp = expf.createValueExpression(ctx.getELContext(), "jsCommandLinkTemp('#{item[0]}'); return false;", Object.class);
link.setValueExpression("onclick",vexp);
col.getChildren().add(link);

the xhtml:

<a4j:jsFunction name="jsCommandLinkTemp" action="#{myBean.actionLink}">
  <a4j:param name="param1" assignTo="#{myBean.idDataTable}"/>
</a4j:jsFunction>

The method actionLink is called and the attribute idDataTable receive the dataTable information, everything works.

Did I do something wrong? I have to pass some attribute to UICommandLink? I don´t want to use JsFunction to call my method.

Thanks (sorry about my english)

As a check, does the corresponding facelet code work as expected?

Tks Brian for the interest.

Yes, using facelet works fine:

<h:dataTable value="#{myBean.someDataModel}" var="item">
  <rich:column>
       <f:facet name="header">col title</f:facet>
       <h:outputText value="#{item[0]}" />
  </rich:column>
  <rich:column>
       <a4j:commandLink execute="@this" action="#{myBean.actionLink}" value="click here">
            <a4j:param value="#{item[0]}" assignTo="#{myBean.idDataTable}" />
       </a4j:commandLink>
  </rich:column>
</h:dataTable>

The method actionLink is called and the param is assign to idDataTable.

Even if i put the attribute: link.setExecute("@this"); not works.

Tks

Can you build a simple reproducer and attach it to a jira issue?  This will enable us to dig in and see what's going on.
