Prevent code suggesting process cancelation on Space press

In my project I have custom code suggestion provider designed for Gherkin language.

Everything works fine until I press space - then suggestion popup disappears. I guess it is expected IntelliJ behavior. 

Of course, suggestions appear again after pressing CTRL + Space, but I wonder if there is any other way to prevent suggestion process cancelation on Space press (either programatically or in IntelliJ settings)?

Hi Patryk,

Please see the last question in the com.intellij.codeInsight.completion.CompletionContributor's Javadoc:

Q: The suggestion popup hides when I type some exotic character, but I want completion to keep going, matching against the typed character.
A: See com.intellij.codeInsight.lookup.CharFilter.acceptChar(char, int, com.intellij.codeInsight.lookup.Lookup).

Hi Karol,

Thank you for the hint, I managed to modify suggestion behavior with custom CharFilter.
