      Hi,

      I want to create a command button with java code which makes same job as follow.

      
<a4j:commandButton id="delete" action="#{controller.delete}" value=" #{msg.delete} ">
 <f:setPropertyActionListener value="#{item.someProperty}" target="#{controller.selected}" />
</a4j:commandButton>


      I have created button and it is invoking method but I cant find how can I set a field or pass a value to the method. I have send class list for expectedParamTypes, I have created method with specified param types, but it didnt invoked the method. 


      
HtmlAjaxCommandButton deleteButton = new HtmlAjaxCommandButton();
deleteButton.setId("deleteCommandButton");
deleteButton.setReRender("dataTable");
deleteButton.setOnclick("if(!confirm('"+WebUtils.getMessage("areYouSure")+"')){return false;}else{this.disabled=true;Richfaces.showModalPanel('busyPanel')}");
deleteButton.setOncomplete("this.disabled=false;Richfaces.hideModalPanel('busyPanel')");
deleteButton.setIgnoreDupResponses(true);
deleteButton.setValue(WebUtils.getMessage("delete"));

MethodExpression deleteMethodExpression = FacesContext.getCurrentInstance().getApplication().getExpressionFactory().createMethodExpression(
 FacesContext.getCurrentInstance().getELContext(),
 "#{controller.deleteMethod}",
 null, new Class<?>[0]
);
deleteButton.setActionExpression(deleteMethodExpression);


      I will be so thankful if anyone suggest me any solution.

          Hello,

          Action method does not have any arguments.
          Create and add this action listener: com.sun.faces.taglib.jsf_core.SetPropertyActionListenerImpl. Note: this would make your code incompatible with MyFaces!

            Nbelaevski thanks so much, I solve the problem.

            
HtmlAjaxCommandButton deleteButton = new HtmlAjaxCommandButton();
deleteButton.setId("deleteButton");
deleteButton.setReRender("dataTable");
deleteButton.setOnclick("if(!confirm('"+WebUtils.getMessage("areYouSure")+"')){return false;}else{this.disabled=true;Richfaces.showModalPanel('busyPanel')}");
deleteButton.setOncomplete("this.disabled=false;Richfaces.hideModalPanel('busyPanel')");
deleteButton.setIgnoreDupResponses(true);
deleteButton.setValue(WebUtils.getMessage("delete"));

MethodExpression deleteMethodExpression = expressionFactory.createMethodExpression(
 elContext, "#{controller.delete}", String.class, new Class<?>[0]
);
deleteButton.setActionExpression(deleteMethodExpression);

ValueExpression target = expressionFactory.createValueExpression(elContext, "#{controller.selectedItem}", Long.class);
ValueExpression propertyValue = expressionFactory.createValueExpression(elContext,"#{dataTableVar}", MyWrapper.class);
SetPropertyActionListenerImpl listener = new SetPropertyActionListenerImpl(target,propertyValue);
deleteButton.addActionListener(listener);

editDelValueColumn.getChildren().add(deleteButton);
