After having to abandon a direct upgrade between Apex 3.2 and 4.2 due to a 4.2 Apex bug during an update from 11.2.0.2 to 11.2.0.3 ( i'll cover the details of this in another post) we ended up having to export all the workspaces/application in Apex 3.2, drop everything. install 4.2 and then import everything in. This worked pretty well apart from the issue i mentioned in my previous post with custom authentication.
The only other issue we really had was some image files weren't working after all the messing around. I initially thought we had forgot to export some images along with the applications (as helpfully this is a separate export - why....???). Anyway it turned out we hadn't missed anything.
So what had gone wrong?
Looking at the APEX code initially i was confusing myself - the image was referred to as #WORKSPACE_IMAGES##AMPEL#.gif
I started along the route thinking #AMPEL# was some clever built in in image for traffic lights and this function had been removed at 4.2 for some reason. Then i thought perhaps it's only available in German language APEX.....
Then i realized that it was just an application variable and depending of the output of some SQL was given a value - so #AMPEL~ ended up as RED/GREEN/AMBER so the file i was looking for was just in the normal location for #WORKSPACE_IMAGES# called coulour.gif.
OK...
So where is that location...?
After looking arounf it seems the images are uploaded into the "FLOWS_FILES"."WWV_FLOW_FILE_OBJECTS$" table. In our frenzy to upgrade to 4.2 we just dropped the FLOWS_FILES schema and let the installation of 4.2 create a fresh (blank) one.
The fix was just to export all the values from the original 3.2 version of the table (which very helpfully has not changed at all) and just import this in with datapump:
