@Meta and @InjectMeta with a boolean type
I saw a neat solution to meta data using annotations in the Vlib example
that comes bundled with Tapestry 4.1.1.
*Code:*
@Meta({"anonymous-access=false", "admin-page=false"})
public abstract class VlibPage extends BasePage implements IErrorProperty,
IMessageProperty, PageValidateListener, OperationsUser
{
...
@InjectMeta("anonymous-access")
public abstract boolean getAllowAnonymousAccess();
@InjectMeta("admin-page")
public abstract boolean isAdminPage();
...
public void pageValidate(PageEvent event)
{
if (isAdminPage()) ensureUserIsLoggedInAsAdmin();
if (!getAllowAnonymousAccess()) ensureUserIsLoggedIn();
}
...
}
Subclasses of VlibPage can over-ride the value for "anonymous-access" or
"admin-page" using the same @Meta annotation:
*Code:*
@Meta( { "page-type=Search", "anonymous-access=true" })
public abstract class Home extends VlibPage
...
I thought I'd give it a go:
base class for pages, defaults meta value to true
*Code:*
@Meta({"meta-secure=true"})
public abstract class BasePage extends org.apache.tapestry.html.BasePage
implements PageValidateListener
{
@InjectMeta("meta-secure")
public abstract boolean isMetaSecure();
...
public boolean isSecure()
{
return true;
}
...
public void pageValidate(PageEvent event)
{
System.out.println(this.getClass().getName() + " - method:" +
isSecure() + " - meta:" + isMetaSecure());
}
...
}
home page over-rides meta value to false
*Code:*
@Meta({"meta-secure=false"})
public abstract class Home extends BasePage
{
@Override
public boolean isSecure()
{
return false;
}
}
list clients page over-rides value to true (for testing purposes)
*Code:*
@Meta({"meta-secure=true"})
public abstract class ListClients extends BasePage
...
list projects page does not over-ride super value
*Code:*
public abstract class ListProjects extends BasePage
unfortunately, it doesn't seem to work. The value always reads false.
*Code:*
$Home_84 - method:false - meta:false
$ListProjects_95 - method:true - meta:false
$ListClients_137 - method:true - meta:false
I've stepped through some stacks and have found that the value is being
correctly set to the String "true" and "false" in the components
properties, but somewhere between
ComponentPropertySourceImpl.getComponentProperty and my property
injected method isMetaSecure, "true" is not being converted to boolean
true.
Has anyone come across this problem?
Has anyone successfully used booleans in meta data via the page
specification as opposed to class annotations?

Thanks Jesse! I'll upgrade as soon as 4.1.2 is released.

Ah...I knew this sounded familiar.
I think it's fixed in 4.1.2-snapshot

If I change the accessor method boolean isMetaSecure to String
getMetaSecure it works fine.
So the problem can be defined as: @InjectMeta only works with String
types. This is obvious after reading the documentation, but the Vlib
example (written by howard?) is misleading as it suggests usage with
booleans works.
