Hello
My Seam application is configured to session length = 60 min. and works within
single long-running conversation during the whole session.
Like in some examples, User is entity bean and session-scoped Seam component at
the same time :
@Entity
| @Table(name = "Users")
| @Name("user"
Still don't undertsand the following.
Under some curcumstances I am getting "property 'someMethod' not found" when
trying to bind action of a:commandButton to method.
Changing action to actionListener with the same method eliminates the error.
How is that possible ?

Still one problem, though .
When I call a method with single argument (argument is entity bean) everything
works well :
JSF code
Java code
public void addPart(PartCMP part)
| {
| cartOrder.addPosition(part, 1);
| }
But when I use 2 arguments, I am getting IllegalArgumentExcepti
Thanks a lot Pete, it was the case. Solved.

Hello
In example 1.23 listing of Seam documentation I see the code :
|
| Name
| #{hot.name}
|
|
| Address
| #{hot.address}
|
|
| City, State
| #{hot.city}, #{hot.state}, #{hot.country}
|

Yes
@Local
| public interface PartSearch
| {
| public int getPageSize();
| public void setPageSize(int pageSize);
|
| public String getSearchString();
| public void setSearchString
