Fixed - Spring '19 Patch 8.0

Lightning component created dynamically via $A.createComponent doesn't get displayed in community if dependency is not declared via <aura:dependency>.

1) Create a Lightning Application:

## Name: W5810911
## Markup:
<aura:application >
<!-- <aura:dependency resource="ui:inputText" /> -->

<aura:attribute name="output" type="Aura.Component[]" access="public" />
<aura:handler name="init" value="{!this}" action="{!c.doInit}" />



## Controller:
doInit : function(component, event, helper) {
$A.createComponent('ui:inputText', {
value: 'Hello world!'
}, function(cmp){
component.set('v.output', cmp);

2) Log in as a community user
3) Navigate to the Lightning app in the community. E.g. https://<sandbox-name>-<community-subdomain>.<instance>.force.com/c/W5810911.app

Actual result: Lightning component (<ui:inputText>) doesn't get displayed. Browser's console shows an error message:

Refused to load the script 'http://.../auraCmpDef?aura.app=markup://W5810911&...&_def=markup://ui:inputText&...' because it violates the following Content Security Policy directive: "script-src 'self' 'nonce-...' chrome-extension: 'unsafe-inline' 'unsafe-eval' https://sfdc.azureedge.net *.visualforce.com https://ssl.gstatic.com/accessibility/". Note that 'script-src-elem' was not explicitly set, so 'script-src' is used as a fallback.

Expected result: Lightning component created dynamically should get displayed to community user.

Ensure the <aura:dependency> declares the dependency with the dynamically created component.

For instance, in the provided markup, uncomment the line that uses the <aura:dependency> component.

On 1st February a short term solution was implemented to fix this issue in all sandbox instances. This known issue will track the roll out of the long term solution.

Is it Fixed?
