When I open New Project wizard and click on Mobile
category, the project templates are shown in the
right list in following order:
Mobile Application
Mobile Project with Existing MIDP Sources
Import Mobility Studio Project
Mobile Class Library
Import Wireless Toolkit Project

But they should be listed in following order:
Mobile Application
Mobile Class Library
Mobile Project with Existing MIDP Sources
Import Wireless Toolkit Project
Import Mobility Studio Project

Part of layer.xml:

folder name="Templates"
  folder name="Project"
    folder name="J2ME"
      attr
name="emptyJ2MElibrary.xml/j2me-sources.xml"
boolvalue="true"
      ...
      file name="emptyJ2MElibrary.xml" ...
      file name="j2me-sources.xml" ...

In the IDE there is
"org.openide.loaders.FolderOrder" class which
implements items ordering in folders.
This class is created/used for J2ME category
folder only when I expand (double-click on) Mobile
category node.
