ADF Faces: dialog framework calls twice prepareModel and prepareRender

Question

Hi ,
does anybody know why ADF Faces dialog framework calls twice prepareModel and prepareRender lifecycle methods . That's a really problem for me because i'm calling db procedures through backing beans methods which are attached on components properties.
I cannot allow myself to cal the procedures more than once.
Can somebody help me?

Okay, although the servlet doesn't require to be run inside the JSF context, I added "/faces" to the URL simply because this would allow me to query the "postback" flag. In other words, I changed the invocation URL from "/jrrun" to "/faces/jrrun".
In the servlet's "service()" method I put:
logger.debug(">>>>>> isPostBack? " + AdfFacesContext.getCurrentInstance().isPostback());
I also attached a JSF PhaseListener to the whole thing.
Then I opened the parent page, I clicked on the button and the dialog appeared. The console output follows:
07/01/19 21:37:05 ------------- start of phase RESTORE_VIEW 1
07/01/19 21:37:05 ------------- end of phase RESTORE_VIEW 1

By the way, partialSubmit="true" has the same effect as partialSubmit="false".
I'm not sure I understand you correctly. Or perhaps you don't understand me correctly.
I haven't got a problem with the parent page. I have a problem with the dialog page. It's executed twice. The RENDER_RESPONSE phase (as well as the RESTORE_VIEW phase) is executed twice.
I want it to be executed only once. I don't want the servlet to be executed twice.
Let me point out again that in the Embedded OC4J (inside JDeveloper) everything is okay. The servlet is executed only once. However, the same thing on OAS 10.1.3.1 runs twice.
