Martin Grigorov commented on WICKET-6002:
-----------------------------------------
How to run the application in my IDE? If you use non-standard ways to do that
then please add it in the steps to reproduce! I'm wasting my spare time trying
to figure out what to do with this rather big application.
Trying to start id.ac.itb.sigit.pengenalanpola.PlatNomorApp as SpringBoot app
fails with:
Exception in thread "main" java.lang.IllegalStateException: Failed to execute

Also please don't scratch your comments but delete them and leave only the
latest version. It is hard to follow you this way.
Now on the issue itself: Spring Boot uses Servlet 3.0 MultipartConfig by
default. Wicket 7.0.0 supports it partially - there is no support for progress
notifications.
I'd recommend to use (exclude = MultipartAutoConfiguration.class) in Wicket
applications.

> *Test case:*
> {code}
> git clone https://github.com/tmdgitb/pengenalan_pola_shih.git -t WICKET-6002
> {code}
> 1. Go to "ChainCode" page
> 2. click "Load Biasa" on the left, you'll see "modeimageModel: null". --> not
> working: using FileUploadField + multipart
> 3. click "Load 3" on the right, you'll see "modeimageModel: WHITE_ON_BLACK"
> --> works: using urlencoded
