project to reproduce

When an Acceleo 3 expression ['test'/] is used in a widget like the text one for value or label expression for example, the expression is not taken into account and the property widget does not show the result of the expression without showing any log explaining why.

The problem is the following: 

Status WARNING: org.eclipse.acceleo.parser code=1 Problems encountered while compiling expression null children=[Status WARNING: org.eclipse.acceleo.parser code=0 A variable should not be named 'self'. This name is an Acceleo or OCL keyword. null]

The problem seems to lie in org.eclipse.sirius.common.acceleo.mtl.business.internal.interpreter.AcceleoMTLInterpreter.createCompilationContext(EObject, String)

The created compilation context contains the self variable that seems to be forbidden by the acceleo interpreter:

The stack leading to this variable setting is the following:

	EEFTabbedPropertySheetPage.setInput(IWorkbenchPart, ISelection) line: 256	
	EEFTabbedPropertySheetPage.selectionChanged(IWorkbenchPart, ISelection) line: 239	

Steps to reproduce:
1- import the attached project.
2-open the "new root" diagram
3-select the EClass

The properties view contains the widget MyWidget that is empty whereas the label of the EClass that is "test" comes from the same A3 expression used in style label. 

4-change the text widget value A3 expression by aql:'test'

MyWidget has the "test" value.
