Environment:

WildFly Full 10.1.0.Final (WildFly Core 2.2.0.Final)
Mojarra 2.2.13.SP1 20160303-1204
Java EE 8
x86_64-redhat-linux-gnu
openjdk version "1.8.0_332"
OpenJDK Runtime Environment (build 1.8.0_332-b09)
OpenJDK 64-Bit Server VM (build 25.332-b09, mixed mode)

We implemented an Upload features to allow students to upload their documents very simply. During the test, we got an HTTP error 413 from our nginx serveur.

However, even if it might be normal to receive a such error, the JSF Ajax tools failed due to an error in javascript and the web page cannot display the error.

We got an NPE equivalent error in javaScript:

undefined is not an object (evaluating 'partialResponse.getAttribute')

JSF Ajax is not able to retrieve the partial response because the partial response does not exist as the NGINX takes the hand. JSF Ajax should/must tests the partialResponse object before accessing it and have a fallback answer.

Actually, the page returns to itself without displaying any error when the file exceed the allowed limit size which is for us less than 5Mb.

ERROR DETAILS

[Error] TypeError: undefined is not an object (evaluating 'partialResponse.getAttribute') response (jsf.js.xhtml:1:38985) onComplete (jsf.js.xhtml:1:29364) (anonymous function) (jsf.js.xhtml:1:29138) callback (jsf.js.xhtml:1:5423) (anonymous function) (jsf.js.xhtml:1:5827)

      var partialResponse = xml.getElementsByTagName("partial-response")[0];
1582 >>>>>> var partialResponseId = partialResponse.getAttribute("id"); var responseType = partialResponse.firstChild;

At the beginning of the file, we catch that:

OpenAjax.hub.registerLibrary("jsf", "www.sun.com", "2.2", null)

We've also prepared an upgraded version of our product and the behaviour is slightly different. May be worst. We have the error "Failed to load resource: the server responded with a status of 500 (Internal Server Error)" but the UI is not able to render the error page. Waiter cursor is not removed and the page is not refreshed. The error is exactly the same as above and it is related to the partialResponse object. Env. is Docker avec WildFly 26.1.1.Final, WildFly Core 18.1.1.Final, et Mojarra 2.3.17.SP01, PrimeFaces 6.0.
