Another dependency problem: org.apache.flex.svg.GraphicContainer contains an internal class called GraphicGroup which extends ContainerBase
GraphicContainer has the following requires: goog.provide('org.apache.flex.svg.GraphicContainer'); goog.require('org.apache.flex.core.UIBase'); goog.require('org.apache.flex.core.IContainer'); goog.require('org.apache.flex.core.ITransformHost'); It also generates the following which contains a reference to ContainerBase: /* FlexJS Dependency List: org.apache.flex.core.ContainerBase,org.apache.flex.utils.Language*/ The problem with this is that org.apache.flex.core.ContainerBase is not guaranteed to load before org.apache.flex.svg.GraphicContainer. If it does not load first, there will be a runtime error on goog.inherits(org.apache.flex.svg.GraphicContainer.GraphicGroup, org.apache.flex.core.ContainerBase); (I was just bitten by this problem.)
