How label IDs are generated?

(0) ShareShare

Posted on by Abby Abraham 314

Hello All

Does anyone have any good documentation on how labels work under the hood? how is the label ID generated?

I am currently facing an issue. When I create a new label, it immediately creates blanks labels in the table ElementModelLabel in all the languages. After restart AOS the En-us language label is created; which is fine and exactly how it should work. 

But why is it creating these blank labels for different languages?

This is currently not affecting our application except for the blank labels for different languages in the ElementModelLabel table.

2nd issue I am facing is we have the same modelStore installed in two different environments. But when I create a new label the next label Id that is generated is not the same in the two environments. EX : If the last label is @ABC206, then in first env the next label generated gets label id @ABC215 and in 2nd env it is @ABC210.

Also Label.maxlabelid("ABC"); returns the above values.

Should'nt both env. be @ABC207?

Where does it get these values.

Thank you

Abby

Thanks

Abby

    That is the expected behavior. If you did not provide translations in other languages you have your License for, the label will be blank there. Label IDs are fetched sequentially within each environment.

    You should be using a Version Control system like TFS hooked up against your developer workspace, in which case labels would go in temporary label files in a format like $AA001 until you check them in to your version control repository. Then they would be replaced with the correct value for the single shared label file. Then from that TFS repository you could synchronize the latest labels to your developer workspaces, or merge the change to other TFS branches to promote the code to Test/Live.

    Hello Vilmos.

    With regards to the blank labels, it looks like it is only for recent labels. Querying on the ElementModelLabel Table, the blank records exists only for the newer labels. I queried for all labels where language != en_us. It only shows the recent labels ( all blank). We have not made any changes to the license etc.

    The two environments in question are not connected to TFS. Would you know the logic for getting the next label id? in the ElementModelLabel table the last label is @ABC206.

    Label fetching happens in the kernel, but from experience I can tell that it is sequential per environment. But you can override that in the XPO Import dialog for example (reusing existing labels, or creating new ones).

    The "fix" is not to create labels in two or more places for the same Label name, and do not transfer code between environments containing code referring to labels which were not uniformly generated because you violated the previous rule.

    Use TFS (or environment-specific label names), problem solved.

    Yes I see your point. The reason why I created the two environments is just to test the label generation. My machine is the only developer machine as I am the only developer. I started investigating this only because when I created a new label it created label id not in sequence. So I created a new env with my model store to further test.

    Currently our process is I develop code. I then import this xpo into a test environement. After testing we export the model store and import this model store to prod.

    We are currently working to implement TFS.

    Thanks.

    Thanks Vilmos for letting me know its the standard behavior.

    I am still trying to figure of how the kernel determines the next Label Id. Playing with the ALD files in the application folder.

    Will post any updates.
