Is it possible to use a variable to replace "Component" in the

There's a few options, yes.
a) the one Lon mentioned -- but beware that it will be slow. Class.for
is a bottleneck if used a lot. But you can overcome this by keeping a
Map<String,Class>.
b) If they're always in the same package, you can bypass the lookup.
String fullName = Main.class.getPackage().getName() + ".Main" +
userGroupCodeString;
return pageWithName(fullName);
c) create a component that dynamically uses a differing template.
Instantiate this component with and utilise WOSwitchComponent in it's
html/wod
java:
protected String componentNameSuffix() {
return session().currentUser().group().code();
}
protected String componentBaseName() {
return "Main";
}
public String componentName() {
return componentBaseName() + "." + componentNameSuffix();
}
Now either do:
html:
<wo:WOSwitchComponent WOComponentName = "$componentName"/>
or the following (which won't require a separate Java file per
component... not recommended unless really useful :-)
java:
protected String _templateName()
{
return componentName();
}
For example how would I change the code below to the syntax above?
String usergroupcodestring = session.currentUser.group().code();
String pageName = "Main"+usergroupcodestring;
return pageWithName(pageName);
The following doesn't work.
String usergroupcodestring = session.currentUser.group().code();
String pageName = "Main"+usergroupcodestring;
return pageWithName(pageName.class.getName());
Thanks,
