    • findParentNamingContainerWithIdPrefix

      public static jakarta.faces.component.UINamingContainer findParentNamingContainerWithIdPrefix(jakarta.faces.component.UIComponent component, String idPrefix)
      Finds the first parent NamingContainer of the given component whose ID starts with the given prefix.
      Parameters:

      public static jakarta.faces.component.UIComponent findComponentWithIdInNamigContainer(jakarta.faces.component.UIComponent component, String ncIdPrefix, String Id)
      Within the first parent NamingContainer of the given component (whose ID starts with ncIdPrefix), finds and returns the child component with the specified ID.
      Parameters:
      component - the starting component
      ncIdPrefix - the ID prefix for the parent NamingContainer
      Id - the ID of the component to find

    • createValueExpression

      public static jakarta.el.ValueExpression createValueExpression(String exprStr, Class cls)

    • openPFDialog

      public static void openPFDialog(org.primefaces.component.dialog.Dialog dlg)
      Opens a PrimeFaces dialog by setting its visibility condition in the viewScope.

      Each CRUD dialog has a visible condition expression: "#{viewScope." + dlg.getClientId().replace(":", "_") + "}" which is set up in solveDlgVisible(). This method makes that condition evaluate to true, making the dialog visible.

      NOT WORKING

      Parameters:
      dlg - the PrimeFaces dialog to open

    • findComponentByClientId

      public static jakarta.faces.component.UIComponent findComponentByClientId(String clientId)
      Removes the visibility attribute for a p:dialog from the viewScope.

      Each CRUD dialog has a visible expression set up via f:event listener="#{drugiBean.solveDlgVisible}" type="postAddToView", specifically in adjustVisibleForDialog(), in the form: "#{viewScope." + dlg.getClientId().replace(":", "_") + "}"

      To make the dialog visible, crudListener() sets this viewScope attribute to true. To hide the dialog, this method removes the attribute so the expression evaluates to false.

      NOT WORKING

      Parameters:
      dlgClientId - public static void removePFDialogVisibleCondition(String dlgClientId) { Mapinvalid input: '<'String, Object> viewMap = FacesContext.getCurrentInstance().getViewRoot().getViewMap(); String dlgClId_rep = dlgClientId.replace(":", "_"); viewMap.remove(dlgClId_rep); System.out.println(" -removed viewScope attribute: " + dlgClientId.replace(":", "_")); System.out.println("_DIALOG CLOSED " + dlgClientId + ", REMOVED viewAttr: " + dlgClId_rep); }
