Hi, > How were you planning on adding the flexunit? By changing installer.xml?
I would add this to the Flex SDK steps so that it show up as an optional component. <component id="STEP_REQUIRED_INSTALL_APACHE_FLEX_UNIT" required="false" property="do.flexunit.install"> <en_US> <label>Apache Flex Unit (Optional)</label> <message>The Apache License V2 applies to Apache Flex Unit. Do you want to install the Apache Flex Unit?</message> <license>Apache V2 License</license> <licenseURL>http://www.apache.org/licenses/LICENSE-2.0.html</licenseURL> </en_US> </component> What I then intended was have the installer run FlexUnits installer.xml script, but if that can't do a MD5 check then I'll have to come up with another way of doing it. Thanks, Justin
