Description

The issues is related to individual styleManager per each IFlexModuleFactory instance. Say, we have a modular application, having
Main "shell" which is <s:Application/> tag and modules loaded in runtime into this shell. Each individual .swf module has it's own styleManager in it.
Shell application is linked SDK as RSL's. Same goes for a module, each module doesn't have sdk linked into it's .swf body.

So the issue is when you have default chart styles stuff declared in the main shell module and shell.styleManager has those selectors at runtime.
But when you loading external module having any chart in it it's module.styleManager doesn't have any chart style selectors, unless you manually
set "module.moduleFactory = shellApplication.moduleFactory".

Once again, instantiate external module .swf get a visual chart component out of this module add it to the shell stage, and bump! you've got an this trace stack:

TypeError: Error #1010: A term is undefined and has no properties.

at mx.managers::LayoutManager/doPhasedInstantiationCallback()[/Users/justinmclean/Documents/ApacheFlex4.11.0/frameworks/projects/framework/src/mx/managers/LayoutManager.as:1188]

So the root cause is a heavy chart components dependency on default styles. Those default styles are not accessible withing external module loaded in runtime.
