How can I clear error messages? Not sure if I'm doing this right.

[Rob Micah]

I have a page that displays a form and when it's submitted it displays a PDF report. The user might back up multiple times to re-submit this form to see the report with different parameters. If the user makes a mistake by entering invalid data the page fails validation and displays errors. If the user then corrects those errors and re-submits the form, the report will run. But if they back up after submitting the form those old errors from the previous submission are still displayed. I am looking for a way to clear the errors in the <h:messages> tags from the page when the user backs up. Is there any way to do this?

As an example here's a description of what happens:

User visits url for first time

User submits form with invalid data

Validation fails and re-displays page populating <h:message> tags

User corrects form data and submits

PDF is output

User presses back button and sees old errors

You should discourage the use of the back button and instead allow them to go back using a commandLink or button on the page. That forces the app to cycle through the JSF life cycle and clear the message queue.

Hi,

try this, add the next line of code after the user re-submits the form (in the methode of your backingbean):

FacesContext.getCurrentInstance().getMessages().remove();
