Problem with LTS License

[michal672]

I configured it as per documentation (by setting primefaces.lts.LICENSE_KEY and primefaces.lts.PASS_KEY with values obtained from the store) in web.xml and adding primefaces-12.0.11-LTS.jar to the build but it keeps showing the red license banner and there is an exception in the server log.

I tried with different JDKs but with no luck.

Could you please generate a new license key at PrimeUI Store and try again?

[michal672]

I generated a new license key (looks like only the key changed while the password is the same) but I'm getting the same errors in each Java.

Thanks a lot for the update! We tried several combinations, but we still couldn’t replicate the issue. We’re currently investigating to find out the exact cause. Could you try running our sample Maven project) using your license key and pass key?

[michal672]

I downloaded the project, changed the primefaces dependency in the pom.xml to 12.0.11-LTS and added key/pass context params to the web.xml. The license check fails with the exception as before and the application displays the red banner.

Thanks, back to the drawing board, but we've finally managed to replicate the issue.

[cagataycivici]

We’ve updated the code generation at PrimeUI Store.

Could you please try generating a new license key?

[michal672]

I confirm the newly generated license key DOES WORK!
Thank You for your help!
