Build Identifier: I20100312-1448 In InternalTransformationExecutor::doLoad, when a transformation cannot be load it will allays do a null pointer exception. Here is an extract of the faulty code (line 257-264 on my version). I added a comment where the problem is and can be corrected. fTransformation = getTransformation(); if (fTransformation == null) { fLoadDiagnostic = new ExecutionDiagnosticImpl(Diagnostic.ERROR, ExecutionDiagnostic.TRANSFORMATION_LOAD_FAILED, NLS .bind(Messages.NotTransformationInUnitError, fURI)); /* At this line if fTransformation has been null it is still null. So checkIsExecutable(fTransformation) at next statement will do a null pointer exception. A simple return at this line correct the issue.*/ } ExecutionDiagnosticImpl validForExecution = checkIsExecutable(fTransformation); Reproducible: Always Steps to Reproduce: 1. Try to call loadTransformation on a qvt library unit. InternalTransformationExecutor te = new InternalTransformationExecutor(uri_lirary); te.loadTransformation();
