Bug #35947 "Export" => "Forward Engineer SQL Create Script" creates wrong SQL Syntax

Description:
I have started to create a database scheme with version 5.0.14 of Workbench. After creating some tables, I found out that the DB scheme is set to InnoDB, so switched to MyISAM. I also added Foreign Key references and also checked the column in the referenced table and also checked the ER-Model every time (always let Workbench recreate it with the the tool under "Model" => "Create Diagram from Catalog Objects". Everything looked good. After finishing the first milestone, I exported an SQL Create Script with "Export" => "Forward Engineer SQL  Create Script". I opened the *.sql file and with copy & paste I added it to the SQL-textarea of phpMyAdmin. When I now startet to recreate the database tables, I got a lot of errors, which you could see in my attachements of wront SQL.

Here are some rewritten examples of errors:
CREATE  TABLE IF NOT EXISTS `mydb`.`table` (
  `name` VARCHAR(45) NOT NULL AUTO_INCREMENT ,
  `hint` VARCHAR(45) NULL ,
  `description` TEXT NULL ,
  PRIMARY KEY (`name`) ,
  CONSTRAINT ``
    FOREIGN KEY ()
    REFERENCES `` ()
    ON DELETE NO ACTION
    ON UPDATE NO ACTION)
ENGINE = MyISAM;

CREATE INDEX  ON `mydb`.`table` () ;

How to repeat:
Not sure, but start a new DB Scheme, add some tables and references, change from InnoDB to MyISAM, add some more tables and then export a SQL create script and check that script in MySQL.

Check for AUTO columns and non-numeric types added.

problems resolved (but only SE Version reports errors in model)

Not sure how to describe the problem. Can you suggest a sentence for the changelog entry? Also need the revision number for the fix. Thanks.

This bug has been fixed but the issue is still open?

was fixed in version 5.0.21

An entry has been added to the 5.0.21 changelog:

When a schema used InnoDB, and then was switched to use MyISAM, the script generated by Forward Engineer SQL CREATE Script still contained InnoDB-only syntax.
