Strange OGNL error binding.
I have hit an error which seems strange, since its the second occurance of the
same sort of thing in the component template. Any ideas where I should look
for the source of this error?
The error is
Unable to read OGNL expression '<parsed OGNL expression>' of
$Border_1@19238ad[Home/$Border]: pageMenuNames
This is from my border component with Border.html having the following line
<span jwcid="sidemenu@Foreach" source="ognl:pageMenuNames"
value="ognl:pageName">
getPageMenuNames is declared in my Border.java file thusly
public String[] getPageMenuNames()
{
return getAppPropertySource().getPropertyValue("menu-items").split("
",0);
}
What makes this more strange is that earlier in the template I have almost the
same thing :-
<span jwcid="mainmenu@Foreach" source="ognl:appMenuNames"
value="ognl:appName">
with getAppMenuNames defined in the Border.java file in almost the same way
thusly
public String[] getAppMenuNames()
{
return _appNames;
}

I *THINK* I understand now - can't do it at application level. .properties
files only work for components and pages?
I guess I have to think about some alternative mechanism to get application
level messages

Yes - it is.
What I am trying to do is read the .properties file of the application that is
using my component. I am trying to create a method to access it via the
following @InjectObject annotation.
@InjectObject("infrastructure:applicationPropertySource")
public abstract IPropertySource getAppPropertySource();
I then call
getAppPropertySource().getPropertyValue("menu-items");
Using debug, I can see that I get the correct property source for the
application, but that the pointer to its properties map is Null.
I assume this probably means that although I have created a properties file,
sitting in the WEB-INF directory the framework hasn't found it and initialise
the property holder for the application.
How do I do that?

I'd bet if you dug down through the exception stack, you'd find the
true culprit, somewhere inside getPageMenuNames(). Probably an NPE.
