Extra View Objects Generated?

Question

I've generated Application Module containing view objects and links. I've got generated four view objects accesors: get<vo>, get<vo>1, get<vo>2 and get<vo>3, but in my project I do not see four view objects, but one <vo>. What happened?
I use view objects in custom application module methods. When working with <vo> everything is fine, except cache refresh. View objects for other entity objects are working good, including refresing cache data.
Any idea?

Hi Djorje,
GLinijaViewImpl is a class, and like most Java classes, it can have particular instances. An app module can contain many instances of the same subclass of ViewObjectImpl, just as a panel can contain many instances of the same subclass of javax.swing.JComponent (e.g., many JButtons).
One reason you might want many instances of GLinijaViewImpl is that you might want them to play different roles in your data model. You might, for example, want GLinijaViewImpl1 to be unrestricted (that is, to execute its query independently) and want GLinijaViewImpl2 to act as a detail to some master query (that is, only return detail rows to whatever row is current in the master query).
What I suggest:
1. Re-enter the application module wizard by right-clicking your app module and chosing edit.
2. Select the Data Model tab.
3. Look at the Data Model tree. It will have all of these instances of the view object in it. I don't know how they got there unintentionally; you might have clicked the > button too many times.
4. You can fix this by selecting the ones you don't want and clicking the < button.
Hope this helps.
Best,
Avrom
