Hi,
ER/D2W will pick an attribute for a related entity. Often, I find,
it picks an attribute I don't want. : < (
Is there any good general way to choose which attribute gets thrown
up in edit/inspect tasks?
For example, let's say we have a person table, related to many
events, which in turn are related to many event-details. This is a
fairly common pattern.
person< >> events< >> details
Q1. If, every time D2W must pick a related attribute from the person
table,
not sure what you mean by "pick a related attribute". Do you mean for
display? If so, I think you can set your "displayPropertyKeys"
globally for your entity.
how can I make sure it is the one I want to use? i.e., override the
default? What is the best general way?
Q2. If I am editing an event-detail, how can I use for a query a
numeric attribute from the person table in a keypath? D2W seems to
only accept strings. I could be doing it wrong, but if I use
something like "person.personNumber" in the key keyWhenRelationship,
D2W gives me an error:
java.lang.NumberFormatException: For input string: "1%"
Are you using ERD2W or just D2W?
Also, when I turn on 'rule tracing': Just where do I seen the rules
being traced?
In the console of Eclipse.
