System Information
Linux Mint 17.3, Intel graphics chipset, Dell Inspiron 15R

Blender Version
Broken: (example: 2.69.7 4b206af, see splash screen)
Blender Edge 2.79 (Dec 30 update)

Short description of error
Repeated extrusion operations in edit mode fail to respect custom transforms. This is a bit of a workflow killer at times. This is because the transform type must be selected every single time to keep using the custom transform. If I have the user transform set to the custom, I expect it to respect that instead of switching to normal for the secondary transform operation. (If I want the normal to be the secondary, then it should be by the user's choosing. The way it is now is a bit broken.)

Exact steps for others to reproduce the error
Create some mesh in edit mode and orientate the object so it's not aligned to the usual global or local axes. Then pick an edge on it to create a custom transform. Then while the custom transform is active, do an extrusion operation elsewhere on mesh using the custom transform by double pressing one of the axis constraints. This will work as expected. However if you try to repeat the constraint, it will revert to normals for the object transformation. It will still show the setting for the custom transform, but extruding more than once fails to respect this setting.

Are you refering to repeat (Shift+R)? This works for me (repeated extrusions with a custom transform orientation)
As for the extruding with the E-key: yes, that defaults to switching to 'Normal + Z constrained' (which I even find reasonable - its just the mostly used for this kind of modeling operation) for the extrusion.
(You propably wouldnt just want to use the orientation that is currently set as the one for the extrusion as well. -- assuming lots of people still have 'global' set as orientation while modeling)

Maybe there's a way to do this with 'double pressing' as you say [so not toggle between 'normal' and 'global', but 'normal' and 'current/custom' while extruding]. Will have a look later, other suggestions welcome...

Single press is global as expected and usual with everything else. But I'd like to have the selected transform option be the one used for the double press. Some other operations respect it in this way, but for some stupid reason extrude doesn't. If I switch to select another face that I want to extrude on the custom transform, then I have to go back to the transforms menu and select the custom edge. It's tedious and creating an extra step that shouldn't be there. Again if I wanted the secondary constraint to be based on normal transform axes, I would have picked that from the menu. (So there shouldn't be any problem with fixing this flaw in the UI. It feels like an inconsistency.)

Also nothing against transforms menu showing "normal" as the default transforms type when starting out. But once the user picks something else, then it should stay with that until the user changes it again. Not this do it once, and then behave as if switched to normal that it does now.

This could be seen as a feature request. In any case it's a limitation of Blender's current architecture/design, and not a bug in its implementation.
