File extension used in AbstractDocumentHandler

[claudio-rosati]

Hello,

in the sample application, then FooHandler uses a file extension set to "foo".

On my mac, when I select Fille > Open ony files named "foo" can be selected when the filter is Foo Document [foo].

To open file whose extension is .foo I have to use "*.foo" instead (displayed as Foo Document [*.foo] filter in the open dialog).

I don't understand if this is a bug or not. In the last case maybe a short description should be provided in the tutorial.

Anyway, once the file is correctly selected, no editor is displayed, no error messages in console.

Configuration:

• OS: MacOS X 10.12.3
• Java: 1.8.0_121
• Maven: 3.3.9
• Env Vars: JAVA_HOME, M2_HOME and M2 are set.
• NetBeans 8.2 IDE (where the maven project is loaded and executed from the inner console).

I have to investigate this and will come back to you.

On Linux, everything works as expected (*.foo are shown and can be loaded). I will check it on a Mac as well.

Hello @puce77,

I've done some tests (see file-chooser-test.zip) to understand how the filter mus be built to work on the various platforms. With the test application one should be able to select a sample.foo file somewere in the disk.

I've installed 4 filters:

• "foo"
• ".foo"
• "*foo"
• "*.foo"

The results are the following:

• "*foo" works both on Windows 7 and Linux (I'm using CentOS 7.1 for the test);
• "*.foo works on MacOS X, WIndows 7 and Linux.

On MacOS X "foo" will selects files without extensions whose name ends in 'foo".

That said, my proposal is to change line 88 of FXFileChooserProvider.java to the following:

.map(fileExtension -> WILDCARD + "." + fileExtension.toLowerCase())

(Or include '.' inside WILDCARD).
