             Summary: how TagEncoder handles duplicate define* tags
                 Key: FLEX-34371
                 URL: https://issues.apache.org/jira/browse/FLEX-34371
             Project: Apache Flex
          Issue Type: Bug
    Affects Versions: Apache Flex 4.12.0
            Reporter: Guest


Suppose there are two DefineEditText tags that are the same by .equals, and a TagEncoder handles them. This writes them both to the SWF, but assigns them the same character ID. Adobe's Flash player can load the SWF fine, but it causes swfdump to crash.

defineEditText(tag) in TagEncoder calls

{code:java}
int id = dict.add(tag);
{code}

When serializing the second DefineEditText, the Dictionary finds the first one and returns its ID. Then, the defineEditText(tag) method writes the second copy with the first one's ID.

Expected result:
either
- it writes the duplicate with a new ID or
- it does not write anything and uses the first copy's ID for references to the second.
