tiles-defs.xml and extended attributes...
Hello,
I have a menuing system using a custom tag to create menus based on
configurations specified in Tiles. I needed to create a more robust solution
for menu specification than was provided by the
org.apache.struts.tiles.beans.SimpleMenuItem. I extended the
org.apache.struts.tiles.beans.MenuItem interface as well. I now have a new
MenuItemExt class that extends SimpleMenuItem and implements my new
IMenuItemExt that extends MenuItem. The extension provides several
additional attributes to a menu item definition beyond that provided "out of
the box".
My problem is this: the new attributes, when specified in tiles-def.xml, are
flagged as errors -
"Attribute 'xyz' must be declared for element 'item'".
Is there a way to define these extended attributes in my TLD file or would
this require an extension to the tiles-config_1_3.dtd (not really
preferable)? What is the correct procedure for declaring these "extra"
attributes such that they are considered "valid"?
Thanks,
-Rod

What do you mean with "extension attributes"? Are they bean properties
of your SimpleMenuItem-subclassed class?

Whahuh? He's talking about the validation of an XML
configuration file from within his IDE.

Apologies for jumping in mid-thread..Can I assume by 'extension' you mean
VaLang?
In which case have you looked at implementing Validation with Spring
Validators?

Hi Antonio,
I agree that that works. In fact, both approaches function identically. That
is not the issue. The only issue I was raising was how to make the
SimpleMenuItem extension attributes validate properly in an IDE. Since, they
are not declared in the DTD, I fear that XML validation will not be possible
(without raising the errors of course).
My choice then is to either allow validation to take place and ignore any
errors regarding the extension attributes -or- disable validation (with the
possible negative side-effect of missing something that should have been
caught by validation - not good). The annoyance of the bogus validation
errors is outweighed by the value of having the rest of the page validated
at design-time and so appears to be the best choice.
Of course, I could always go and change all menu templates to use the bean
definition approach instead - it makes no difference to the code, everything
works just fine.
Thanks for the response,
-Rod

I think that you should use <bean> instead of <item>, that takes
<set-property> elements too.

I think that you should use <bean> instead of <item>, that takes
<set-property> elements too.
