Hi all,

unfortunately my grammar's comment terminal rules look like this:

terminal SL_COMMENT: "%" !("\n" | "\r")* ("\r"? "\n")?;

terminal ML_COMMENT: "%{" -> "%}";

so they have a common prefix. I think this causes the following problem:
Here's my auto edit strategy provider:

	private static void accept(IEditStrategyAcceptor acceptor, IAutoEditStrategy strategy) {
		acceptor.accept(strategy, IDocument.DEFAULT_CONTENT_TYPE);
		acceptor.accept(strategy, TerminalsTokenTypeToPartitionMapper.COMMENT_PARTITION);
		acceptor.accept(strategy, TerminalsTokenTypeToPartitionMapper.SL_COMMENT_PARTITION);
	}

	public static final String[][] BLOCK_KEYWORD_PAIRS = { { "{", "}" }, //$NON-NLS-1$ //$NON-NLS-2$
		{ "%{", "%}" }, //$NON-NLS-1$ //$NON-NLS-2$
		{ "<<", ">>" } }; //$NON-NLS-1$ //$NON-NLS-2$

	@Override
	protected void configure(IEditStrategyAcceptor acceptor) {
		accept(acceptor, defaultIndentLineAutoEditStrategy.get());
		for (String[] blockKeywordPair : BLOCK_KEYWORD_PAIRS) {
			accept(acceptor, singleLineTerminals.newInstance(blockKeywordPair[0], blockKeywordPair[1]));
			accept(acceptor, multiLineTerminals.newInstance(blockKeywordPair[0], null, blockKeywordPair[1]));
		}
		final String[][] brackets = new String[][] { { "[", "]" }, //$NON-NLS-1$ //$NON-NLS-2$
			{ "\\(", "\\)" }, //$NON-NLS-1$ //$NON-NLS-2$
			{ "(", ")" } }; //$NON-NLS-1$ //$NON-NLS-2$
		for (String[] blockKeywordPair : brackets) {
			accept(acceptor, singleLineTerminals.newInstance(blockKeywordPair[0], blockKeywordPair[1]));
		}
		accept(acceptor, partitionInsert.newInstance("\"", "\"")); //$NON-NLS-1$ //$NON-NLS-2$
	}

Unfortunately, when I type %{, only } is inserted, not %}. How can I circumvent this?

Thanks in advance,
thSoft
