Hi all,

I want to change one instance content.

such as

when I create a list instance ,I want to create one default item .and then
if list type is changed , its default item contents are changed .is it possible.

I can use handle.notification or changer.notification ? How can I do this with xtext.

Can you help me ?

Sorry, but it is really difficult to understand what you are asking.

Hi Henrik,

My grammar's related part is below :

CustomList returns CustomList:
	'CustomList'
	name=QualifiedName
	'{'
	'displayName' '=' displayName=STRING
        ('description' '=' description=STRING)?
	 'type' '=' type=ListType
	 ('contentTypes' '{' ownedContentType+=ContentType 
         (ownedContentType+=ContentType)* '}' )?                           
		
	'}';
      
       ContentType returns ContentType:
	'ContentType'
	name=QualifiedName
	'{'
		'displayName' '=' displayName=STRING
		('description' '=' description=STRING)?
		('group' '=' group=STRING)?
		('parentContentType' '=' parentContentType=        [ContentType|QualifiedName])?
		('fields' '{' ownedField+=Field (ownedField+=Field)* '}' )?
		('releatedTable' '=' releatedTable=[Table|QualifiedName])?
	'}';
Field returns Field:
	LookupField | TextField 
	;
enum ListType :
custom|DocumentLibrary

When I create a CustomList instance and I select type =custom in the xtext editor ,
Automatically created ContentType item and ContentType's contens that are field :
TextField or LookupField are created automatically.And then
if I select type=DocumnetLibrary ,previously created "item" ContentType's name will change with "documentlibrary" and its default fields will change.

I want to automatically instance and change its name and contents automatically

I hope I can explain my problem Sad
