Attempting to use self mada filter results in notices and warning, no result [#1436704]

Added MediaWiki filtering to Plain Text type. When using the markups, doing a preview results in several notices and warnings of the type:

Notice: Undefined index: components in flexifilter_filter_prepare() (line 405 of /var/www/htdocs/drupaldev/sites/all/modules/flexifilter/flexifilter.module).
Warning: Invalid argument supplied for foreach() in flexifilter_invoke_components() (line 322 of /var/www/htdocs/drupaldev/sites/all/modules/flexifilter/flexifilter.module).

and the previews remain unformatted by the MediaWiki filter.

Attached is a pdf print of the page in question.

I'm haveing the same issue as described above, but using a self made php code (coming from here: http://drupalcode.org/sandbox/risca/1200940.git/tree/refs/heads/master).
The error is exacly the same.

We've got the same kind of issue in this post: #1760466: Mediawiki demo filter does not work with Drupal 7.15. I'll report this there.

edit: at mine, it was solved by using the dev release: 7.x-1.0-beta2+1-dev

OK. I am running Drupal version 7.38 and I download the 7.x-1.0-beta1 on 20180405.
I did not try the MediaWiki. But I did follow the Back To Top Tutorial.
It does not matter if I create the filter or using the provided import, both failed.

I debugged the code and located the error and fix it in flexifilter.module (see attached). With the error, I see no reason the MediaWiki will work.

The other not so serious problem I found is with -Structure -Flexifilters -Preview. It report attempt to convert array to string. I replaced one check_plain() with json_encode() and the message is gone. Again, see the attachment for patch.

Thanks.
