Bugs in GEF v05

Each bug is named with a unique string (e.g., "save_memory_hog"). For some bugs there are comments in the code that indicate where the bug is manifested. Also there are references in the feature list to these bugs. You can follow the references by using a multi-file search command (e.g., grep) or you can use tags if you use emacs. A tag file with entries for bugs and features can (soon) be downloaded from the GEF web site.

When sending a new bug report please check the GEF home page for specific instructions and existing bugs that describe your problem.

Bugs observed on all platforms:

• BUG:shift_click
  Shift-click when selecting does not always do the right thing. It should deselect an item that is already selected, but it does not. Shift-drag seems to work.
• BUG:rectilinear_arc_constraints
  ArcPerspective does not draw properly. It looks pretty bad and sometimes the lines make a "T" intersection when it should make a right anngle turn. I know that there are missing cases to the logic that decides how to draw the arc. This really needs to be totally redone.
• BUG:focus_for_redraw
  Undersome browsers the applet frames will not be redrawn until you move your mouse into the frame.
• BUG:save_memory_hog
  Saving large documents with connected nodes requires setting the amount of stack space used by the Java VM. Use "java -ss1m" to set the stack size to 1 Mb, by default the stack size is something like 4 Kb. Unfortuanely, you cannot set the stack size in the appletviewer or most browsers.
• BUG:saved_file_versioning
  Since there is no versioning support in Sun's ObjectSerialization library, if you change your class definitions there is no easy way to load files saved with the old class definitions.
• BUG:arc_translate
  ArcPerzRectilinear should move when both their end points move at the same time. To see what I mean: place two nodes, connect the nodes, select all objects, move the nodes all around. You will see that some points on the arc stay put.
• BUG:rectilinear_arc_points
  ArcPerzRectilinear inserts too many points when it does it's initial routing. There is no command to redo the routing. And FigPoly's even/odd convention for rectilinear polylines is not followed properly, so it is possible to get diaganol lines if you drag some handles around. Also, self-arcs (arcs that go from a port on a node to another port on the same node), are not routed properly.
• BUG:save_under_jdk1_0_2
  I updated my version of Sun's ObjectSerialization libary, and much to my dispare I found that saving and loading no longer work under jdk1.0.2. The problem is that classes such as java.util.Hashtable must implement java.io.Serializable, but they do not in jdk1.0.2. So there is really nothing I can do, other than stop using Hashtables and Vectors. Instead I just use jdk1.1.1 for building applications. (Applets cannot currently load or save anyway, but adding the ability to use a URL would be a good project).
• BUG:switch_tabs_without_apply
  When auto-apply is off, users can loose changes if the switch tabs before pressing the "Apply" button.

• BUG:sun_choice_not_shown
  Some Choice components are not drawn, but you can still click on them and use them.
• BUG:sun_no_key_focus
  In InBrowserApplet.html the drawing area is in the same frame as the palette. Keystrokes are intercepted by AWT so you cannot type keyboard commands for GEF and you cannot type text into a FigText.

• BUG:win_no_button_background
  Button colors cannot be changed to highlight which command is "stuck" when you set the "sticky" check box.
• BUG:win_list_double_click
  List items send their action event on mouse-down when the user double clicks. It should be on mouse-up. The effect is that you can spawn a new editor from the Execute Action window and the first events it will recieve will be mouse drag, without ever seeing a mouse down event. That can cause unexpected behavior.
• BUG:win_color_picker_buried
  The ColorPickerGrid window should come to the front of all windows when you click on a PropEditorColor. Under jdk1.1.1 on windows the call to toFront() has no effect.
• BUG:win_prop_sheet_grabs_focus
  The TabPropFrame property sheet sometimes jumps in front of other windows when it is not desired. This also sets the keyboard focus to the property sheet window, so you can no longer tab through DiagramElements unless you click on the editor window to assign keyboard focus back there.
