Unable to update the URI fragment of proxy element on Edapt Migration [message #1803350] Wed, 27 February 2019 09:41 Go to next message

I got stuck on updating the proxy URI of reference element and I have not much experienced in creating custom edapt migration , Below is my scenario

I have " ParentClassA " which has ereference to " RefClassB". Attribute "linkID" is been used to Identify this object.

" linkID " will be calculated based on few factor/other attriubtes in RefClassB and its eContainter.

Now, I have changed the way "linkID" is being calculated. I want to make an edapt migration to support this.

I tried below code,

for (Instance parameterInstance : model.getAllInstances("ParentClassA ")) {			Instance identifierInstance = parameterInstance.getLink("RefClassB");
identifierInstance.getUri().appendFragment(getLatestURI);
}


getLatestURI is again based on the attributes on "RefClassB", Since ,being proxy element, I am unable to get req.details from identifierInstance .

Is there any edapt operation to support the change of URI proxy value? I tried few custom migration, nothing got worked. Please someone help me on this,

NOTE: ParentClassA will be on one file and RefClassB on another file.

Hi,

You can change the URI like this:
final Instance refClassB = ...;
refClassB.getResource().setUri(URI.createFileURI("/new/path/name.xmi"));


Was this the only thing you were missing?
I think you have access to all ParentClassAs and can get the RefClassBs from them, so you should have everything to determine the linkID and the new URI

Cheers

Johannes,

Problem is "refClassB " will be available in different file and that file is not been migrated along with current file migration.
Content in file 1:
<ParentClassA  name="test" ...... >
<RefClassB href="file2.xml/ABC-DEF" />
</ParentClassA >

I am trying to migrate something like,
<ParentClassA  name="test" ...... >
<RefClassB href="file2.xml/QWER-XYZ" />
</ParentClassA >


I was able to do this, when all the contents are present in same file via custom migration , but my scenario is that I splitted the content in different file and try to make migration one file by another.

Also, I am not sure how to make whole project to get migrated..

Thanks in advance !

Hi,
I quickly tested spiting the model to different files and it worked for me.
Are you using some custom URIConverters or something like that? Could you maybe provide a reproducible example so that I may debug it?
Cheers
Johannes
