XPAND and XSD adapter [message #498084]

Hi,

To isolate a problem with namespace I created a minimalistic project, and now even without namespace. And it seems that suddenly nothing works anymore.

The template editor shows errors for all types and elements that they are not resolvable. But the Reader can read the xml and the Generator processes the first 2 elements (root and entity) but then fails with TheName of entity.

[23,38] on line 1 'EXPAND templates::main::Root FOR model'

For easy reproducing I have uploaded the project to http://drop.io/9t38ntm

Most probably I am blind again. This project is so simple and still I can't see what is wrong.

hi, the problem is quite simple to solve:

modify the template like this

«DEFINE entity FOR EntityType»
	«theName.value»
«ENDDEFINE»

by the way. it helps you if you put your metamodel into a source folder and enable the xsd metamodels in the xtend/xpand section of your projects preferences. then you'll get e.g. code completion in your templates

Thank you Christian.

Now I have re-introduced the namespace in the XSD and get the following error which is the same as in my real project:

SEVERE: Error in Component  of type org.eclipse.xpand2.Generator: 
	EvaluationException : No Definition 'templates::main::Root for type::AnyType' found!
	[23,38] on line 1 'EXPAND templates::main::Root FOR model'
