Bug #64916
Updated by Markus Klein over 9 years ago
UserInternalContentObject is trying to serialize ContentObjectRenderer.
This leads to severe issues also uses lots of memory.
If you set up a page like this
<pre>
page = PAGE
page.10 < styles.content.get
page.20 < plugin.tx_felogin_pi1
</pre>
Install sysext:felogin and add static templates for CSC and felogin!
Add a "text w/image" CE to the page and add at least one image.
you'll get an Exception in FE: Serialization of closure not possible.
(In order to see the Exception you need to set the application context to Development and select the Development-preset in Install Tool.)
The reason is that if the Core is not installed via composer, a closure is registered in the SignalSlotDispatcher.
For some reason, when serializing ContentObjectRenderer, also SignalSlotDispatcher is serialized, which leads to this exception.
The solution is to remove the "hard-wires" between ContentObjectRenderer and TSFE and File(Reference).
