Migration of Xtext1.0 to Xtext2.3, Methods not found [message #1006593]

I followed the migration guide from http://www.eclipse.org/Xtext/documentation.html#migrating_from_1_0_x but i Could not find the alternative for the following methods in Xtext 2.3 which were present in Xtext1.0

1. NodeUtil.getNearestSemanticObject(AbstractNode node)
2. ParseTreeUtil.getLastCompleteNodeByOffset(CompositeNode node ,int offset);
3. NodeAdapter.getNodeAdapter(EObject obj);
4. NodeUtil.findASTElement(CompositeNode root);
5. NodeUtil.getRootNode(EObject obj);

Any Help will be much appreciated.

Hi in NodemodelUtils (findactualsemanticobjectfor) and inode
(getrootnode) may be some of the things you are looking for (have a
look at the java docs)

You will find replacements for everything. There is stuff that is
obsolete like getnodeadapter since the node model technically changed

Thanks Christian for your response.
I have one more doubt, There was a class in Xtext 1 as org.eclipse.xtext.MweReader which was deprecated, URIBasedReader is to be used as an alternative if i am not wrong, but i could not find an appropriate method equivalent to doValidate.

Hi as far as I remember the new class is simply called Reader

Hi,

I was successful in migrating all parts except the Editor Validations. As suggested i tried using error(String, EStructuralFeature) instead of error(String, Integer), but then i get the following error :
ERROR org.eclipse.xtext.validation.CompositeEValidator - Error executing EValidator
java.lang.IllegalArgumentException: The sources EClass 'ABC' does not expose the feature 'DEF'.

I am using it like
@Check(CheckType.FAST)
public void checkValue(final ABC abc) {
//some logiv....
error("Value does not match",Epackage.Literal.DEF);
}

Id expect something like my pack.literals.ABC__Name
Or pack.literals.ABC__somethingelse

Can you tell why you use DEF

Dear All,

I need your favor or suggestion regarding migrate the xtext version from 1.0.1 to 2.3.0 in custom application.

I followed all following process for migrate the xtext version.
1. Delete the old plug-ins and update the latest plug-ins in target platform.
2. Update the Plug-in Dependencies and Import Statements.
3. Introduction of the Qualified Name.
4. Changes in the index and in find references.
5. Rewritten Node Model.
6. AutoEditStrategy.
7. Other Noteworthy API Changes
To consider the above steps, I started the work with Eclipse-4.2, Which has a xtext-2.3.0 dependency. Successfully I completed the all above steps and removed the compilation error.

Problem: After that I start the testing and getting below error Messages:
[XtextLinkingDiagnostic: null:6 Couldn't resolve reference to Material 'MPS_RECUR'.,
XtextLinkingDiagnostic: null:9 Couldn't resolve reference to Cstic 'NUM_OF_ALLOC'.,
XtextLinkingDiagnostic: null:15 Couldn't resolve reference to Cstic 'INSTANCE_NUM'.,
XtextLinkingDiagnostic: null:14 Couldn't resolve reference to Class 'ALLOC'.]
