Hi Folks,
I am looking for the best way to initialize a session variable(@Persist) in
a page render request once, so I could access it in the next action request.
I tried to put the logic into "pageAttached" method like below:
====
@Persist
private xxx myVar;
@SuppressWarnings(value = "unused")
private void pageAttached()
{
if (myVar == null) initializeVar();
}
====
It doesn't work as I expected. myVar is always null in "pageAttached"
method. It seems the "pageAttached" method is not supposed to mutate a
persistent variable.
However, if I put this logic into some other place like below, it works
fine.
====
@Persist
private xxx myVar;
public String getSomeOtherVar()
{
if (myVar == null) initializeVar();
return someOtherVar;
}
====
Although it works, apparently, this is not a good place.
Is there a better place to do session variable initialization?
I believe it should not be put into constructor too because it will be
viewable to other sessions.
Thanks,
Jeffrey Ai
