Stephan Plath commented on FLEX-34118:
--------------------------------------

Workaround: include the desired chart components in the main (shell) application:
{code}
	private var dummyChart: LineChart;
	private var dummySeries: LineSeries;
{code}

> 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.

> 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.
