How to set HtmlActionParameter value dynamically?

[leiras]

I know how to set it in static way.

<a4j:actionparam name="xxx" value="#{item.id}" assignTo="#{auditoria.idAuditoriaSelecionada}" />

But it is not working dynamically

HtmlActionParameter actionparam = new HtmlActionParameter();
actionparam.setValueBinding("apName", application.createValueBinding("#{item.id}"));

What is wrong in my code? Thanks.

I change the static way to work with "bindind" instead "value", like this:

<a4j:actionparam name="xxx" binding="#{item.id}" assignTo="#{auditoria.idAuditoriaSelecionada}" />

and it keeps working with no problem. But the dynamic way is not working.

HtmlActionParameter actionparam = new HtmlActionParameter();
actionparam.setValueBinding("vb", application.createValueBinding("#{item.id}"));
actionparam.setAssignToBinding(application.createValueBinding("#{origem.selectedId}"));

The value assigned to "origem.selectedId" is always null.

Could someone help please? Thanks a lot.

I think the correct way is use the method "setValue" instead "setValueBinding", like the following code:

actionparam.setValue("#{item.cnpj}");
actionparam.setAssignToBinding(application.createValueBinding("#{origem.strTeste}"));

but the value assigned to "origem.strTeste" is always the string "item.cnpj" when actually should be the content of the property called "cnpj". How can I do that?

Have you gotten this to work yet ?

I too am struggling with this problem.

This seems to work for me:

org.ajax4jsf.component.html.HtmlAjaxCommandLink link = new org.ajax4jsf.component.html.HtmlAjaxCommandLink();
link.setId( "link" );
javax.faces.component.html.HtmlOutputText title = new javax.faces.component.html.HtmlOutputText();
title.setId( "title" );
title.setValue( "My Link" );
link.getChildren().add( title );

org.ajax4jsf.component.html.HtmlActionParameter ap = new org.ajax4jsf.component.html.HtmlActionParameter();
ap.setId( "param" );
ap.setName( "username" );
ap.setValue( "Alex" );
javax.faces.application.Application application = context.getApplication();
javax.el.ExpressionFactory ef = application.getExpressionFactory();
javax.el.ValueExpression ve = ef.createValueExpression( context.getELContext(), "#{userBean.name}", UserBean.class );
ap.setAssignToBinding( ve );

link.getChildren().add( ap );

link.addActionListener( ap );
