Hi there,
MacOS 10.1.5 & WO5.0
I'm just staring to use WO recently and also a beginner of Java programming.
I would like to have your advices for my qestion.
What I am trying to do in WO application is
1. Create a new record in an entityA using display group insert().
2. Save the new record in the entityA using saveChanges().
3. Create a new record in an entityB using insert().
4. set a value of an attribute of entityA to an attribute of the entityB
5. saveChanges() of entityB.
I want to do the process 2 to 4 by an action on a WO component.
What I did to set the value was to add
entityB.aData = entityA.aData;
in the action method in the java file.
Both entityA and B was produced as a key using the entities.
And it doesn't allow me to finish the build.
I think I had to use a method, something like "takeValueForKey".
But I don't know how to use it.
Question1 : what method can be used to set a value of an entity to a field
of the other entity?
Question 2 : I am learning WO by myself and had read some books for WO but
when I get lost like this case, what kind of documents, do you think, are usefull?
I checked the documents of the WO: EOControl, Java reference for Java etc.
But I don't think it is useful.
Any comments would be appreciated.
Thanks in advance.
