How to rendering f:validateBean validationGroups value

[wish79]

Hello All,

  i have <f:validateBean   validationGroups="#{operationBacking.validationGroupExper}"> as you see it get the groups value from experssion becuase i need dynamic groups name , but when i render the form(that include my code) to get new value the validationGroups still work validation on the old value(old group) while the value change becuase i add the experssion on h:ouputlabel it get new value when i render the form :

code :

<h:outputLabel value="#{operationBacking.validationGroupExper}" />

<f:validateBean   validationGroups="#{operationBacking.validationGroupExper}">

is it problem or f:validateBean dose not support render from other component i.e(it take the value one time) ?

The validationGroups EL may be getting evaluated at the time it is put in the component tree, and not re-evaluated after you update the value.

Thanks, is there any work around

You could look at invoking your bean validation programmatically.

Faced with the same issue. Came out with a hack based on this article: Delete the components holding unwanted state | LogikDevelopment.

Basically, you need to remove from tree components you want to update validators for, so they will be reinitialized during rendering.

E.g. if you are executing a section with ajax, you can call a method like this in action listener:

public void resetContactsValidationGroups() {

  Iterator<String> ids = FacesContext.getCurrentInstance().getPartialViewContext().getExecuteIds().iterator();
  while (ids.hasNext()) {

       FacesContext.getCurrentInstance().getViewRoot().findComponent(ids.next()).getChildren().clear();
   }

}
