Hi list, hi David,

I've played a bit more with this and created my own subclass to override
classForAttributeColumn:
public String classForAttributeColumn(D2WContext c) {
String base = (String) c.valueForKey("baseClassForAttributeColumn");
String auxiliaryCssClass = (String) c.valueForKey("auxiliaryCssClass");
base = base + " " + cssClassForPropertyKey(c.propertyKey()) + base;
if (auxiliaryCssClass != null) {
base = base + " " + auxiliaryCssClass;
}
return base;
}
Using two rules, I get what I want:
100 : (pageConfiguration = 'ListSalesOrder' and propertyKey = 'customer.id') =>
classForAttributeColumn = <ERMDDefaultCSSAssignment>
[com.elumo.d2w.assignments.ELCSSAssignment],
100 : (pageConfiguration = 'ListSalesOrder' and propertyKey = 'customer.id') =>
auxiliaryCssClass = object.customer.paymentBehaviour
[er.directtoweb.ERDDelayedKeyValueAssignment],
But, surprisingly for me, I have to declare "object" as a dependant key for it
to work:
@SuppressWarnings("unchecked")
protected static final NSDictionary keys =
ERXDictionaryUtilities.dictionaryWithObjectsAndKeys( new Object [] {
new NSArray(new Object[] {"object"}), "classForAttributeColumn"
});
I thought that since I'm using ERDDelayedKeyValueAssignment in the second rule,
this should not be necessary? Then again, I guess by default my assignment
would be caching according to the dependant keys in the superclass?
Anyway, as this is my first foray into writing assignments - is this an OK
approach or could this be handled differently?
Fabian
P.S.: I got really confused when rules I had disabled in RuleModeler were being
evaluated and in the course changed the caching behaviour. Is this normal?
