[forge-issues] [JBoss JIRA] (FORGE-1246) CommandScopedContext may not be supported in a shared environment
George Gastaldi created FORGE-1246:
--------------------------------------
Summary: CommandScopedContext may not be supported in a shared environment
Key: FORGE-1246
URL: https://issues.jboss.org/browse/FORGE-1246
Project: Forge
Issue Type: Enhancement
Components: UI - API
Affects Versions: 2.0.0.Alpha13
Reporter: George Gastaldi
Priority: Minor
Fix For: 2.x Future
CommandScopedContext uses a static LinkedList to store the current UIContext. This is not
suitable if forge is run in a shared environment, like a web application for example.
One solution would be to introduce a unique identifier and store the UIContext in a map:
{code:java}
public interface Identifier {
public String getIdentifier();
}
@ApplicationScoped
public class GlobalIdentifier implements Identifier {
public String getIdentifier() {
return "DEFAULT";
}
}
// Enable this if run in a web environment
@SessionScoped
@Alternative
public class SessionIdentifier implements Identifier {
public String getIdentifier() {
// return the session identifier
}
}
{code}
and CommandScopedContext could lookup this object to fetch the specific reference
identifier.
In CommandScopedContext:
{code:java}
@Override
public void contextInitialized(UIContext context)
{
Identifier id = ...; // lookup using BeanManager
CONTEXT_MAP.put(id.getIdentifier(),context);
}
private UIContext getCurrentContext()
{
Identifier id = ...; // lookup using BeanManager
return CONTEXT_MAP.get(id.getIdentifier());
}
{code}
