[jboss-user] [JBoss Seam] - @Factory on initial page load
Hi,
I've got a Search screen where users will enter their criteria.
Below this I have an area for the results to be displayed.
My problem is that the @Factory for the results section runs on the first load of the page
and as no criteria have been entered it will return all records in the database.
Obviously this is not what I want to achieve and the only solution I have at the moment is
putting a whole bunch of if else statements in my bean to determine if the factory should
run or not.
Eg look at my @Factory code and then my doSearch() method which is really where I want to
do my validation!

|
| FacesContext.getCurrentInstance().addMessage(null, message);
|
| }
|
| getUvFactors();

| }
|

Can someone tell me how I can either
1. Not run the Factory on the first load of the page
2. Not display the error message that no search criteria has been entered on the first
load of the page
Thank you
