Hi,
I'm trying to understand how to display error messages that are indication of some exception cases in the Backing Bean.
There is no validation involved, but I would like to show up an error message telling the user that a "Delete action on the table row " has failed.
I use the FacesContext.addMessage - but this takes the clientID as the argument. Is it always necessary to harcode this id in the Backing Bean?
My code looks like this
<h:form id="elementForm">
<h:message for="elementTable" showDetail="true" showSummary="true" errorStyle="color:red" />
<h:dataTable id="elementTable"
……
And in the handler where the exception is thrown
catch (NoObjectFoundException exception)
{
FacesContext.getCurrentInstance().addMessage("elementForm:elementTable",
new FacesMessage("The Object does not exist .Unable to delete the specified row. Please check the \n"
+ "logs for detailed error message !!!" ));
return null;
}
Thanks
Balaji
