Hi,
I have so far only programmed Self Servicing, now I am programming Adapter, which I find actually even better to use, since it provides a little better layer structure, since the entities don't have CRUD methods anymore.
It also provides me with a little more structured code, since I really have to fetch the data I need programmatically. With selfservicing it can be done use lazyloading. Which is very easy to program, but it tends to be too unpredictable, but that's probably me coding this.
Anyway, I find a lot of things very easy to to, with the buckers, transaction etc. The only problem I have run into is what to do with Collections.
I used to have a ProjectEntity which had a collection of ProjectTasks as a property.
So I could easily say Project.ProjectTask[0].TaskNo to get my task no of the first projecttask.
With adapter I don't really know how to work with this...
There are two things I used to do with collections. Keep them as a child of an entity, like Project and ProjectTasks and I use to have them as single collection object, for example a collection ServiceLines.
These servicelines I could just call fill them using a filter and I had a collection filled with ServiceLine Entities which was of type ServiceLineCollection.
In adapter I just have an entity collection. My problem is now: How do I know which type it is, or do I always have to say: (ServiceLineEntity)ServiceLineCollection[0] to get the first ServiceLine?
And also: If I have a Project with ProjectTasks, how do I do: txtTaskNo = Project.ProjectTask[0].TaskNo in adapter code? Since it's not a typed collection?
I also want to know how to use a stand alone collection. I mean, I can fill it with adapter, using a filter. But how do I know WHICH entities I am filling it with and do I declare it as an EntityCollection and have to convert it all the time to the correct entity?
Please help me...
Gr.,
G.I.
