RTextArea.read() stops auto code completion from popping up

[Jatoxo]

I have a basic autocompletion setup like this:

CompletionProvider provider = createCompletionProvider();
AutoCompletion ac = new AutoCompletion(provider);

ac.setAutoCompleteEnabled(true);
ac.setAutoActivationEnabled(true);
ac.setAutoCompleteSingleChoices(true);

ac.setAutoActivationDelay(800);
ac.install(codeEditor);

private CompletionProvider createCompletionProvider() {
		DefaultCompletionProvider provider = new DefaultCompletionProvider();

		for(String instruction : AssemblerBefehle.getAssemblyInstructions().getMnemonics()) {
			provider.addCompletion(new BasicCompletion(provider, instruction));
		}
		provider.setAutoActivationRules(true, null);

		return provider;

}

And it works fine and pops up automatically as it should, but when calling .read on the RSyntaxTextArea to open a file, it no longer automatically pops up. The suggestions will still show when pressing ctrl + space. Even calling setAutoCompleteEnabled(true), setAutoActivationEnabled(true) and setAutoActivationDelay(800) again after reading a file, the box will not pop up.

Rarely, if I immediately type a letter upon opening a file, it will actually pop up the suggestions, but only for that one time.

The bug here is that AutoCompletion registers a DocumentListener on the current Document, see this line in AutoCompletion. We should probably automatically uninstall and reinstall this listener when an RSTA instance's Document is updated.

While not great, as a workaround until this is fixed, you should be able to do the following:

try {
    autoCompletion.uninstall();
    textArea.read(new BufferedReader(...));
    autoCompletion.install(textArea);
} catch (IOException ioe) {
    // Handle the exception
}

This will be in the 3.1.6 release.
