Opening a PsiFile

Hi there, and thanks for all your help so far. I'm pulling data from an API and making a new document out of it. I'm using PsiFileFactory.createFileFromText() and it returns a PsiFile. I then want to open it in an editor. From what I understand I'm supposed to use psiFile.navigate() for this, but it fails because the file isn't saved in a directory yet. I would prefer not to save the file locally if I can avoid it (ala scratch pad). But I can't seem to find anyway to accomplish this. Any feedback would be appreciated, thanks in advance.
