Resource doesn't exist [message #496394]

Hello guys,
I'm working on a RCP app. Since a couple of days I come in trouble with
some exceptions saying that a resource doesn't exist. I want to open the
registered editor for a file on the disk and then the exception is
thrown. I imagine that it comes because of the architecture of my
workspace. The real physical files on disk always get a unique name by
generating a UUID. In the project explorer those cryptical names won't
be displayed but rather "readable" names for the physical files. When
one double-clicks on a name in the project explorer internally the
physical file will be figured out, the appropriate registered editor and
then IWorkbenchPage.openEditor(file, editorID) will be invoked. I see
the files on the disk but always the mentioned exception is thrown.
That's why I imagine that the files aren't really registered in the
workspace or something similar because while debugging I saw that in the
class Workspace and method getResourceInfo the check tree.includes(path)
returns false. I create the physical files with normal java method
File.createNewFile(). Is this my fault? Do I have to do this anyhow in
"Eclipse" way?

Eclipse doesn't know about the files you have created in the disk
directly. You can let it know the changes by the corresponding
folder.refresh()

Use Eclipse API to create the file: IFile.create()
