Hi, I'm busy building support for the "is" and "as" operators into FlexJS. Now, first I thought I'd try to compile the FlexJSTest_again example. To my suprise, I get an error:
CSS codegen problem. Reason: 'Unable to find compilation unit for Embed(source="Assets.swf",symbol="mx.skins.cursor.BusyCursor")' The error seems to originate from FalconJx, it is thrown in JSCSSCompilationSession.java... Now, my sources are fresh, I've rebuild the SDK (super-clean main), all compiler projects (wipe main) and the FlexUI.swc. Am I missing something (command line arg) or is there some source not yet committed or something more obvious I'm overlooking? These are my arguments: +env.PLAYERGLOBAL_HOME=/Users/erik/Documents/ApacheFlex/dependencies/PlayerGlobal/player +playerglobal.version=11.1 -load-config="/Applications/Adobe Flash Builder 4.7/sdks/4.10.0/frameworks/flex-config.xml" -library-path+=/Users/erik/Documents/ApacheFlex/git/flex-asjs/frameworks/as/libs/FlexJSUI.swc -js-output-type=FLEXJS -closure-lib=/Users/erik/Documents/ApacheFlex/dependencies/GoogleClosure/library -sdk-js-lib=/Users/erik/Documents/ApacheFlex/git/flex-asjs/frameworks/js/FlexJS/src /Users/erik/Documents/ApacheFlex/git/flex-asjs/examples/FlexJSTest_again/src/FlexJSTest_again.mxml EdB On Thu, Oct 31, 2013 at 6:37 AM, Erik de Bruin <e...@ixsoftware.nl> wrote: > I'll have a look at it today. > > EdB > > > > On Wednesday, October 30, 2013, Peter Ent wrote: >> >> Thanks, Erik.
