Steve,
Have you tried putting it in the user.d2wmodel file instead of the
d2w.d2wmodel file?
Dave
Yeah. Makes no difference. But if I remove the lhs from the rule, I get
the desired result (no edit/delete buttons) - of course, I need to be able
to turn that on and off.
Is there any way to intercept the rule firing on code? Subclass
D2WContext somehow (doesn't look probable)? Seems this rule is evaluated
from D2WUtils in a static method. Phooey.
I'd have to do something grotesque like turning off concurrent request
handling and munge the rule array on every appendToResponse.

I'm trying to remove the edit/delete buttons from the UI of a D2W app by
using the "readOnlyEntityNames" rule. I'd like to make the result of this
to be conditional on a Session method "noEdits()".
I put this rule in my d2w.d2wmodel (using RuleEditor):
{
author = 50;
class = "com.webobjects.directtoweb.Rule";
lhs = {
class = com.webobjects.eocontrol.EOKeyComparisonQualifier;
leftKey = "session.noEdits";
rightKey = 1;
selectorName = "isEqualTo";
};
rhs = {
class = "com.webobjects.directtoweb.Assignment";
keyPath = readOnlyEntityNames;
value = (User, Group);
};
}
This is the *only* rule in this file. FYI, the only rule in user.d2wmodel
is
{
class = com.webobjects.directtoweb.Rule;
author = 100;
rhs = {
class = com.webobjects.directtoweb.Assignment;
keyPath = look;
value = "BasicLook";
};
}
D2W.factory().newSignificantKey("session.noEdits") has been added to
Application.java
The edit/delete buttons always show however. When tracing the rule firing,
I only see the default readOnlyEntityNames rule:
****** fire : *true* => readOnly=isEntityReadOnly (-1)
****** fire : *true* => readOnlyEntityNames=()
(com.webobjects.foundation.NSMutableArray) (-1)
If I rummage through the D2WModel _rules array at runtime, I can find my
rule. If I manually call the fire() method on my rule, I get the expected
("User", "Group") array.
Anyone have any ideas on what I'm doing wrong? Suggestions on how to do
this easily? (Editing the rules is pretty much out of the question, this
is a boiled down version of an existing app whose rule file is 18000+ lines
- but "no code", jeez!!).
