[news.eclipse.modeling.m2t] Re: Run JET template from java error

[zhao-yong@xxxxxxxxxxx (Frank)]

I debug with jet source, it throw a exception, please note ///////: 

public boolean doEvalCondition(TagInfo td, JET2Context context) throws 
JET2TagException
 {

   String testXPath = getAttribute("test"); //$NON-NLS-1$
   var = getAttribute("var"); ///////var is null    
   XPathContextExtender xpathExtender = 
XPathContextExtender.getInstance(context);
   
   // get the result of the xpath expression prior to casting to boolean, 
in case we define a 'var'.
   Object rawObject = 
xpathExtender.resolveAsObject(xpathExtender.currentXPathContextObject(), 
testXPath);///////throw a exception which means not support 
isVariableDefined function
   
   boolean processContents = XPathUtil.xpathBoolean(rawObject);
   if(processContents && var != null)
   {
     varAlreadySet = context.hasVariable(var);
     if(varAlreadySet)
     {
       savedValue = context.getVariable(var);
     }
     context.setVariable(var, rawObject);
   }

   return processContents;
 }
