Migrating dynamic PanelMenu richfaces 3.x to 4.x
Hello everyone, I have a dynamic menu where I get data from database to create it in version 3.x of richfaces, but I'm moving to 4.x and I have a problem with
import org.ajax4jsf.component. html.HtmlActionParameter;
therefore not found in 4.x. I tried to use
import org.richfaces.component.UIParameter; import org.ajax4jsf.component.UIActionParameter;
however does not work as HtmlActionParameter. What would be the new class version 4.x for HtmlActionParameter? Here my code
Version richFaces 4.x
