-**Common Problems**+**Controller Reference** 
 + 
 +For all scripts where you need a reference to the tool interface (or host definition) you will need to get this interface using TransSECSController.getSingleController() or TransSECSController.findController("XXXXX") where XXXXX is a specific tool interface. If you only have one interface in your project the preferred way to access the interface is using the getSingleController() method without using a specific tool interface name.
  
-if you see an error such as: 
-TypeError: null has no such function "someFunctionName", this usually means you forgot to add an import for a class which has method "someFunctionName". 
-For example: 
-TypeError: null has no such function "findController" or TypeError: null has no such function "getSingleController" is commonly due to forgetting to do this: 
  
 <code javascript> <code javascript>
 var TransSecsController = Java.type("com.ergotech.transsecs.secs.TransSecsController");  var TransSecsController = Java.type("com.ergotech.transsecs.secs.TransSecsController");

-before you do this: +
-<code>+
 secsInterface=TransSecsController.findController("PLCTool");  secsInterface=TransSecsController.findController("PLCTool");
