Plug-ins ignore file set by the auto-detect file format function

[Nicklas Nordborg]

This happens in the ReporterMapImporter and in the RawDataFlatFileImporter. I don't know if it happens in other plug-ins as well. I guess the problem is in the web client which forgets the file that was selected in the auto-detection step.

1. Create an array design and select file 'A' as the reporter map file. This file can be any file that doesn't match a configured file format.
2. Click on the "Import" button and select auto-detect. The 'A' file should already be selected in the 'File' field.
3. Click on 'Browse...' and select file 'B' instead. This file should match a defined reporter map file format.
4. Click on 'Next...'
5. If a file format is found a new page showing more parameters is displayed
6. Select 'Reporter map file' parameter.
7. The value of this parameter is the 'A' file.

Workarounds:

1. Click on 'Browse...' in the last window and select the 'B' file again.
2. Don't select file 'A' as a reporter map file in step 1 above.

The reason for this behavior is that if a file is already selected as the 'reporter map' file the plug-in sets this file as the default value. This has higher precedence than the most recently used file in CurrentContext which is where the auto-detected file is stored. I guess the priority order should be:

1. The auto-detected file
2. The default value
3. Any other recently used file

The problem is entirely in the web client code.
