Extension problem #2775

Closed XiaoXiaoYi123 closed 5 years ago

XiaoXiaoYi123 commented 5 years ago

Hello, I was surprised to find this tool very useful.So I tried to expand it. First, I examined the.sct file, which I found to be composed of two sections of the ecore file, sgraph.ecore and notation. Ecore. Then, I tried to generate the sgraph.ecore instantiation file, and there were a lot of problems. Finally, the generated results are as follows:

<?xml version="1.0" encoding="UTF-8"?>
<xmi:XMI xmi:version="2.0" xmlns:xmi="http://www.omg.org/XMI" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:notation="http://www.eclipse.org/gmf/runtime/1.0.2/notation" xmlns:sgraph="http://www.yakindu.org/sct/sgraph/2.0.0">
  <sgraph:Statechart xmi:id="_VgBc4Iv6Eemg6-kEj95RIA" specification="internal:&amp;#xA;&amp;#x9;var x: integer&amp;#xA;&amp;#x9;var y: integer&amp;#xA;&amp;#x9;event ev1&amp;#xA;&amp;#x9;event ev2&amp;#xA;&amp;#x9;event ev3" name="folding_01">
    <regions xmi:id="_VgBc4Yv6Eemg6-kEj95RIA" name="main Region">
      <vertices xsi:type="sgraph:Entry" xmi:id="_VgBc4ov6Eemg6-kEj95RIA">
        <outgoingTransitions xmi:id="_VgBc44v6Eemg6-kEj95RIA" target="_VgBc5Iv6Eemg6-kEj95RIA"/>
      </vertices>
      <vertices xsi:type="sgraph:State" xmi:id="_VgBc5Iv6Eemg6-kEj95RIA" name="DoorOpened" incomingTransitions="_VgBc6Yv6Eemg6-kEj95RIA">
        <outgoingTransitions xmi:id="_VgBc5Yv6Eemg6-kEj95RIA" target="_VgBc5Iv6Eemg6-kEj95RIA"/>
      </vertices>
      <vertices xsi:type="sgraph:State" xmi:id="_VgBc5ov6Eemg6-kEj95RIA" name="DoorClosed" incomingTransitions="_VgBc6ov6Eemg6-kEj95RIA">
      </vertices>
    </regions>
  </sgraph:Statechart>
</xmi:XMI>

I found the generated file and the sgraph of the.sct file.Ecore is almost identical, but when I open my generated file using yakindu, there are a few errors

However, there is no error when opening this portion of yakindu generated with the yakindu tool. Looking forward to your help.Thank you !

There is a transition missing with the incoming xmi:id _VgBc6Yv6Eemg6. However, you should not create the XMI "by hand" - use the EMF Framework instead to avoid dealing with such low level details like XMI Ids.
