Populating a web page?
In Struts I can use the action method to call some method to get the data and populate the
form, but what is the best way of doing this in myfaces (JSF)?
I.e I am on one page and going to another, but before rendering the other page I need to
get some data from a database...
Regards,
BTJ

I think this is where something like Shale will help - having your
backingBean implement ViewControlloer
http://struts.apache.org/shale/features.html#view You would use the
prerender() method to populate your form with what you needed. I'm new to
all of this (JSF/Shale) but in the process of trying to get something like
this to work.**

The way I do it is to have page1.jsp make a call to a backing bean method
that fills global variables with data. Note that my backing beans that do
this are defined in the session scope. Another way to do it would be to pass
the necessary information via the <f:param> tag. You can imbed that tag
within a commandLink, for instance, and when the user clicks the button the
appropriate action method will be executed, and in that action method you
can retrieve the value passed on <f:param>.
