_fruit_toggle.py example doesn't work, CompoundRules broken?

[jgarvin]

Speaking, "I like bananas" or "I like apples" does nothing.

If I copy and paste the MappingRule from the outlook_example.py into _fruit_toggle.py, and add the rule to the same grammar object as the apple/banana rule, the phrases in it are recognized correctly. So dragon/natlink are working. So it appears just plain CompoundRules are broken?

I went ahead and wrote a MappingRule version which works just to be sure:

The fruit toggle example works fine for me in WSR.

DNS user here, I can confirm this bug. Actually, for me it works inconsistently. If I alternate between saying, "I like apples" and "I like bananas", sometimes it triggers the rule and sometimes it doesn't, and just prints the text of what I said.

@synkarius Does the MappingRule version work for you?

[synkarius]

@jgarvin Yes, and without the inconsistency.

The fruit_toggle.py example works just fine as-is, meaning two CompoundRule instances added to a single Grammar. Thus, I find that CompoundRule is not broken and there is no need to use MappingRule or to otherwise modify the original macro in any substantive way. I find that this script produces consistent alternation of the active rule. It works whether I dictate optional text, or whether I do not.

To verify this in a scientific way, I just now dictated "I like bananas" and then "I like apples" 10 times in a row, for a total of 20 sequential recognitions. At that point I was sufficiently convinced that there is not a problem.
