title: dynamic connectors in Visio .vdx files
body: <p>Currently I am trying to understand .vdx files, because in the future I want to generate my own. I'm having problems with dynamic connectors. When defining them as follows:</p>
  
  <pre><code>&lt;Shape ID="46" Type="Shape" Master="10"&gt;
  &lt;Geom IX="0"&gt;
  &lt;MoveTo IX='1'&gt;&lt;/MoveTo&gt;&lt;LineTo IX='23'&gt;&lt;/LineTo&gt;&lt;/Geom&gt;
  &lt;/Shape&gt;
  ....
  &lt;Connect FromSheet="45" FromCell="BeginX" FromPart="9" ToSheet="1" ToCell="PinX" ToPart="3" /&gt; 
  &lt;Connect FromSheet="45" FromCell="EndX" FromPart="12" ToSheet="23" ToCell="PinX" ToPart="3" /&gt; 
  </code></pre>
  
  <p>they are not displayed. After moving a node, the connectors are displayed. What am I missing?</p>
  
  <p>When taking the minimal settings from a Visio generated .vdx file, there are lots of coordinates, which I want to avoid:</p>
  
  <pre><code>&lt;Shape ID="47" Type="Shape" Master="10"&gt;
  &lt;XForm&gt;
    &lt;PinX F="Inh"&gt;1.669258233656828&lt;/PinX&gt; 
    &lt;PinY F="Inh"&gt;7.519214852067909&lt;/PinY&gt; 
    &lt;/XForm&gt;
  &lt;XForm1D&gt;
    &lt;BeginX F="_WALKGLUE(BegTrigger,EndTrigger,WalkPreference)"&gt;1.737275462308963&lt;/BeginX&gt; 
    &lt;BeginY F="_WALKGLUE(BegTrigger,EndTrigger,WalkPreference)"&gt;7.671541057367827&lt;/BeginY&gt; 
    &lt;EndX F="_WALKGLUE(EndTrigger,BegTrigger,WalkPreference)"&gt;1.601241005004693&lt;/EndX&gt; 
    &lt;EndY F="_WALKGLUE(EndTrigger,BegTrigger,WalkPreference)"&gt;7.366888646767992&lt;/EndY&gt; 
  &lt;/XForm1D&gt;
  &lt;Geom IX="0"&gt;
  &lt;LineTo IX="2"&gt;&lt;X&gt;-0.1664424255025283&lt;/X&gt;&lt;Y&gt;-0.3046524105998358&lt;/Y&gt;&lt;/LineTo&gt;
  &lt;/Geom&gt;
  &lt;/Shape&gt;
  </code></pre>
  
  <p>What is the best and easiest way to work with dynamic connectors in .vdx files?</p>
  
  <p><strong>EDIT:</strong> With Visio 2010 it is much better, and the connectors are shown most of the time. So it really looks like a Visio bug...</p>
