There are two types of errors in the sample that you sent, one of which has been corrected and one of which is being actively investigated. The workaround while this is under investigation is to use the graphical DTL editor in the System Management Portal.

ERROR #5001: attribute 'sourceclass' is not declared for element 'transform'

ERROR #5001: attribute 'sourcedoctype' is not declared for element 'transform'

ERROR #5001: attribute 'targetclass' is not declared for element 'transform'

ERROR #5001: attribute 'targetdoctype' is not declared for element 'transform'

These errors have been reported to the Atelier development team here at InterSystems and are being investigated. We do not have a timeline for the fix, but you can always reach out to the WRC to check in on the status of the internal report.

ERROR #5001: element 'assign' is not allowed for content model '(annotation?)'

This error has been corrected, starting with Ensemble 2017.2.1. If you are seeing this when compiling against later versions of the product please send us your version string (by clicking the About link in the top-left of the System Management Portal).

Hi Connor, I've been working with Michelle Stolwyk on this one and I do not think this is a large-scale issue with the stable Atelier repository. I just installed Java 8, Eclipse Photon, and Atelier 1.3.139 (from the stable repo https://atelier.jfrog.io/atelier/updates/stable/1.3/) on a fresh machine without any problems.

I think the issue on your system does boil down to a security/proxy problem. Here is an article I've used to help with this type of issue in the past: https://stackoverflow.com/questions/21076179/pkix-path-building-failed-and-unable-to-find-valid-certification-path-to-requ.

If you are still having trouble I would suggest reaching out to InterSystems Support (by calling +1 617-621-0700 or emailing support@intersystems.com) for help with your specific configuration. InterSystems will not be the authority on how to configure a proxy, Java certs, etc. But we can point you in the right direction and send some resources that our customers have used in the past.

I would suggest first checking the browser you have selected in your Eclipse settings. From the preferences page, select General > Web Browser and confirm that the expected browser is selected.

Next take a look at the settings in your IE 11 browser to check the Emulation settings. (In the F12 Developer Tools make sure that the Document Mode selected there is not 7.)

If you are still having trouble I think we'll need to look into your system-specific settings, such as the operating system, exact build of IE, etc.. That would probably be best handled by InterSystems Support.

As an aside - Atelier is supported on the Eclipse Photon release, not on the 2018-12 release. I do not necessarily think this will solve the problem you are seeing now, but we have seen this cause other problems when using the Atelier plugin. So I would suggest getting a fresh install of the Eclipse Photon client here then install Atelier on this new client.

David opened a WRC case and we are looking into the cause of this issue. I'll post the resolution here in the DC once we are done with our investigation.

======

Update 11/26/18: We were not able to get to the bottom of this, as David reached a point where he was unable to spend the time to investigate further.

This is not possible at the moment. But it is something that has been requested by customers before, and it is on the Atelier development roadmap!

My best guess from the description here is that the CSP application was not created properly in the Atelier Project. Currently you cannot create a new CSP application at the Atelier Project level - you need to copy the CSP app from the server. For example:

1. Create a new web application in Caché:

2. In the Atelier Server Explorer, right-click that new CSP application and copy to an Atelier Project (you may need to refresh the server connection for the new application to show up):

3. Create a new CSP page and select the newly copied CSP application:

4. The CSP page should compile as expected in the new web application:

If you would like someone to dial into your system and debug this with you, you can always contact InterSystems Support (by emailing support@intersystems.com or calling +1 617-621-0700).

Development is aware of this issue. We do not have a timeline on when it will be fixed.

If you would like to track the progress of the development change, I would suggest opening up a WRC case (email support@intersystems.com or call +1 617-621-0700). A Support advisor will be able to link the relevant development change to the WRC case then you can keep track of it using the new UX in the WRC application.

Be sure that:

1. The Caché/Ensemble/HealthShare/InterSystems IRIS instance that you are trying to connect to is version 2016.2+.
2. Your web server (listening on the web port that you provide in the Server Connection Configuration dialog) is configured to handle requests starting with /api/atelier. The Atelier documentation explains how to do this for an IIS web server here, but the same principle applies to all web servers. Atelier makes REST requests to communicate with the server and those will start with /api/atelier instead of /csp like many other CSP requests.
3. The /api/atelier web application is enabled at the Caché level. To do this:
   1. Launch the System Management Portal and select System Administration > Security > Applications > Web Applications
   2. Select the /api/atelier application
   3. Check the Enabled boxes for Application and CSP/ZEN and Save

If you are still having trouble I would suggest reaching out to InterSystems Support (email support@intersystems.com or call +1 617-621-0700).
