Deleting a file with unsaved changes [message #336464]

Does anyone know what is controlling the severity of "File 'x' has unsaved
changes." problem in the "Confirm Delete" dialog?

If I try this scenario with basic eclipse text editor, the message
severity is warning and I can still delete the file.

If I try this scenario with a custom multi-page editor that I wrote, the
message severity is error and I cannot delete the file.

Thanks,

Anyone? It is clearly a platform facility that is getting in the way here,
but I haven't been able to any information about any switch that I might
be able to set to switch this message from error to warning the way it
should be.

Searching for the "unsaved changes" message I came across
checkDirtyFile(...) in
org.eclipse.ltk.internal.core.refactoring.resource.DeleteRes ourceProcessor
which seems to drive the behavior you are seeing. The logic is something
like,

1. Get the ITextFileBuffer for the IFile
2. Make sure its dirty
3. If the buffer's state is validated AND synchronized, make it a warning
4. Otherwise make it an error

You'll have to dig into the buffer API to figure out how to influence
the state. Not something I'm familiar with.

Ben,

Your help in digging this up is much appreciated. This was enough for me
to chase down the problem to a missing call to the text editor's
validateEditorInputState() method prior to driving any text buffer changes
from the design page of my editor.

Thanks!
