<p class="MsoNormal"><span lang="EN-US" style="font-family:"Courier New""><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">I think the reason is, in our metamodel the same library is attached multiple times. Once directly and also indirectly inside other libraries.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">For example the metamodel includes “lib A” and “lib B”, but “lib B” also includes “lib A”.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">So the metamodel includes 2 times “lib A” with the same GUID.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">For the Library Refresher itself, it seems to be no problem to have the same library multiple times with the same GUID.
<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">But to avoid GUID ambiguities GME changes the GUIDs of one of the included “lib A”s automatically every time the metamodel is opened.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">If I want to refresh “lib A” now, the GUIDs of the included library and the original library are not identical and the Library Refresher can’t solve the references.
<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">(As I understand the Library Refresher compares the “BinGUID” (project_guid , element_guid) of elements in the old and new library for restoring the references.)<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">My suggestion would be, to ensure that included libs get new, but deterministic, GUIDs while being attached to a metamodel/library or getting refreshed.
<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Maybe the GUID of the library and the GUID of the project (metamodel/library) could be combined as new GUID.
<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Or the namespaces of the libraries are used to get an unique identifier.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Thanks and kind regards<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Thorben<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">P.S. I tried to set up a minimal example, but in the example always the GUID of “lib A” included in “lib B” is changed. Thus there is no problem with refreshing “lib A” in the metamodel.
<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">However in our real metamodel the GUID of the “lib a”, directly included in the metamodel, is always changed on opening the metamodel.<o:p></o:p></span></p>
