!!! Tutorial Printer Problem - DiaFlux

DiaFlux models are an intuitive implementation of flowchart knowledge. 
That way, the dialog behavior as well as the derivation behavior is modeled as a flowchart, where nodes correspond to questions to be asked and solutions to be derived. 
Edges between two nodes describe a dependency, e.g., the subsequent questioning in a dialog or the subsequent derivation of a solution.
DiaFlux models are usually partitioned in small models that can call each other in order to describe a complex model.

!! Handling Connection Problems

A new DiaFlux model is created by inserting the following (empty) markup into the wiki article.

{{{
%%DiaFlux   
%
}}}

After saving the article, KnowWE provides a link to visually edit the empty model.
When clicking the link, a new window with a visual editor is opened.
In the editor, you can drag an drop questions from the left menu pane into the editor panel. 
Please insert a start and a stop node (from the toolbar) into the flowchart first.
Then we open the hierarchy ''Printer '' left menu

!! Defining the Initial Questionnaire

We define the entry of the knowledge base, where the user is asked about the general problem with the printer.
A new DiaFlux model is created by inserting the following (empty) markup into the wiki article.

{{{
%%DiaFlux 
  
%
}}}

As depicted in the image below, we also marked this DiaFlux model as the ''Autostart'' mode, i.e., the model started at the beginning of a user dialog.


[{Image src='DiaFlux Printer Entry.png' width='800' align='left' caption='Definition of the entry flowchart of the Printer Problems knowledge base.' }]

We see, that the question ''Please specify your problem'' is asked at the beginning. 
Then, the questionnaire ''Connection Questions'' and ''Quality Questions'' is
