Hello;
Thanks for the quick response. I turns out that I was using the
control correctly but I found that the associative table that is
created by EOModeler, the columns and table name are not defined in the
module. Once you assign the names to the columns and the associative
table then you can use the WOToManyRelationship control. :) He,he.
Thanks

Hi Don,

I bind my control in the following manner:
<ScreenSnapz.jpg>
In my form, I am inputting a process image and wanting to display the
evidence associated with it. Your EO is going to have the toMany
relationship (in this case evidences) and you have to select the key
you want to display (in this case I am displaying the numeric ID).
Your source is the instance of the object you are inputting using the
form and the Entity is your object.
From looking at your code, I assume you are entering the Area Codes in
an Audit form. If that is the case, you probably want the following
bindings:
Datasource: null
DestinationDisplayKey: "description" (pick an identifying
characteristic of the AreaCode EO)
isMandatory: null
relationshipKey: "issueAreaCodes" (the to many relationship in your
Audit EO)
sourceEntityName: "AreaCode" (the name of the EO)
sourceObject: anAreaCode (or whatever you have called your instance of
the object)
I hope that helps,
David
Audits >> issueAreaCodes < issueAreaCode
When I attempt to use a WOToManyRel in my form I get a null pointer
exception. I have been trying for a week to get this to work. I
have the to-one relationships working with no problems. Just the
WOToManyRel is not working.
I have the following in the properties:
Datasource: null
DestinationDisplayKey: "description"
isMandatory: null
relationshipKey: "issueAreaCodes"
sourceEntityName: "Audits"
sourceObject: projectData
Thanks,
Don Lindsay
