Hi anybody,

In my szenario I have different grammars, which refer to different file-suffixes:

.wf: workflow-files
.mask: mask-files

I have some crossreferences between these files,
e.g:

in a file vsa.marvin.mod.schulung.workflow.CustomerManagement.wf:

workflow-language-v2.0 package vsa.marvin.mod.schulung.^workflow;

import vsa.marvin.mod.schulung.^workflow.OverviewMask;

.....

javaMask OverviewMask


I can't resolve these crossreferences anymore.
I debugged and came to the following problem:

In ImportScope.getLocalElementsByName(QualifiedName name) there is a call:
importFrom.getExportedObjects(type, resolvedName,isIgnoreCase()
This tries to get all exported objects of the parentpackage, I guess, again calling ImportScope.getLocalElementsByName(QFN). This time there is only one normalizer in the list (vsa.marvin.mod.schulung.workflow.CustomerManagement.*). It tries to resolve the OverviewMask-Import by append the relativeName (in this case vsa.marvin.mod.schulung.workflow.OverviewMask), leading to an resolved name "vsa.marvin.mod.schulung.workflow.CustomerManagement.vsa.marvin.mod.schulung.workflow.OverviewMask", which is wrong and doesn't find any elements.

How do I get a importoptimizer that resolves vsa.marvin.mod.schulung.workflow.OverviewMask in a correct way?
Would be nice, if you could help me.

Best regards
Markus

Hi, can you please add the Information on your scoping setup? How does the grammar Look like. How is scoping configured in the Workflow/RuntimeModule? What does your customized Resource/Linking? Can you Share a reproducable example? ~Christian

Hi Markus,

there are by default a number of import scopes nested into each other.
If one cannot find something meaningful in its parent package, it will
simply delegate with the plain name to it (see
AbstractScope#getElements(QN)).
The unresolved references are probably not caused by the behavior that
you observed in the debugger.

Regards,
Sebastian

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'.]
