AEM/Oak: check if jcr:content node is present - xpath

As CQ/AEM creates corrupt pages if an author using the language copy tool to only copy children to the other language, but not the parent, I implemented a tool that checks for these corrupt pages and has a way to fix them. In CQ 5.6.1 I used the following XPath:
/jcr:root/content//*[#jrc:primaryType='cq:Page' and not(jcr:content/fn:name()='jcr:content')]
I'm now running the same code on an AEM 6 instance and this query doesn't work anymore though the error doesn't make sense to me:
/jcr:root/content//*[#jrc:primaryType='cq:Page' and not(jcr:content/fn:name((*))='jcr:content')]; expected: )
Though as you can see it added (*) in the fn:name function for some reason.
So, either how to fix this query for Oak or how could I check for corrupt pages in AEM 6?

This works for me on AEM 6.1
/jcr:root/content//element(*,cq:Page)[not(jcr:content)]

How to add prefix in URI while loading XQuery file using ml-gradle

I am using gradle 6.8 and MarkLogic version is 10.0-5.2,
My XQuery code is in directory \ml-gradle\src\main\common. When I run the command mlLoadModules to load XQuery into the modules database it loads with default URI /common/test.xqy.
I want to add some prefix to the URIs e.g. /rsc/common/test.xqy. How can I achieve that?
Note: I don't want to create an extra folder in my source for prefix "rsc".
It's not supported, though you could write a custom Gradle task to change the URI to whatever you like.
Why do you not want to create an "rsc" folder above "common"? I think other developers would find it much more intuitive that "rsc/common/test.xqy" becomes "/rsc/common/test.xqy" when loaded, rather than "common/test.xqy" becomes "rsc/common/test.xqy", which begs the question - where is "rsc" coming from? And then that developer would need to understand what property / custom code is adding that "rsc".

How do I debug work of 2sxc if Visual Query works perfectly during debug, but cshtml code can't access data?

I've edited some existing visual queries of Blog 4.0 application and when I was debugging it - it worked perfectly. But then on page it stopped working. Any attempt to use key with Data like Data["Posts"] raises System.Collections.Generic.KeyNotFoundException. App.Query["Blog Posts List"]["Posts"] returns something, but any attempt to access its fields raises another exception (don't remember the name, but it said that there's no such member inside that object).
I didn't rename queries, I didn't change application settings. I just edited logic of 2 queries. I renamed 1 wiring endpoint name across 3 queries in whole chain.
How do I debug it? How can I see what does cshtml receive from database so I don't guess and put my crystal ball away?
In general, App.Query["Name of Query"] will get you the streams of data. You usually need to convert it using AsDynamic() or AsList() to something you can work with.
This should help some; What is Data?
If you're just running into problems with field names, you probably forgot the AsList or AsDynamic, just like #accuraty-jeremy mentioned.
For real debugging, go to insights, you'll see what happens - but in your case it probably won't help, because your working with an object that's not dynamic (so doesn't support .FirstName) until you AsList/AsDynamic it.
My bad: I confused two different files - _List.cshtml and _List Paging.cshtml. So I was searching for an error in the code of wrong file.

rails generate ckeditor:install --orm=active_record --backend=active_storag not worked Rails 5

I want to use in my project ckeditor with active storage, but when I generate to install ckeditor using orm active record and active storage, it create an initializer but not create any migration file.
Running via Spring preloader in process 23128
create config/initializers/ckeditor.rb
route mount Ckeditor::Engine => '/ckeditor'
Could not find "active_record/active_storage/ckeditor/asset.rb" in
any of your source paths. Your current source paths are:
/home/arif/Development/Test
Project/cable_test/lib/templates/ckeditor/install
/home/arif/.rvm/gems/ruby-2.4.2/gems/ckeditor-
4.1.3/lib/generators/ckeditor/templates
So I ran into this as well, and after poking around the code I figured I'd just run the generator without the flags like the docs. If you run into this problem just run the generator with no flags rails g ckeditor:install. Also, you'll need to look at these files and make sure your models match.

EDIT: It looks like active_storage is only available on the master branch as of this post.

How to add an application to Apache Brooklyn catalog

I am trying to add applications into Brooklyn catalog. can anyone explain steps to add a new application to catalog.xml?
I did try the sample catalog provided at https://brooklyn.incubator.apache.org/v/0.7.0-M1/use/guide/quickstart/policies-and-catalogs.html . The application gets listed in catalog tab but when I try to launch it, it gets stuck at 'configuring'. Is there something else that needs to be done ?
I tried adding existing application to catalog ( https://brooklyn.incubator.apache.org/v/latest/ops/catalog/index.html ) but it failed. Can anyone help me with this ?
I'd strongly recommend upgrading to 0.7.0-M2-incubating, as the catalog has significantly improved since 0.7.0-M1. The documentation at https://brooklyn.incubator.apache.org/v/latest/ops/catalog/index.html describes the steps for 0.7.0-M2-incubating; they will not work for 0.7.0-M1.
The link to an explicit version of the docs (rather than latest) is https://brooklyn.incubator.apache.org/v/0.7.0-M2-incubating/ops/catalog/index.html
There are also more improvements in snapshot (and in existing pull requests), if you fancy trying the bleeding edge!
For the 0.7.0-M1 error "gets stuck at configuring", we'd need more info (e.g. logs, etc). Suggest you e-mail the mailing list or jump on IRC if it's still a problem (https://brooklyn.incubator.apache.org/community/mailing-lists.html).

Core Data Migration error message "'Model does not contain configuration 'XYZ'.'"

I have a Managed Object Context to which I add two different SQLite stores. I use Configurations in the Mananged Object Model to assign certain entities to one store and other entities to the other. The Configurations are called "UserDB" and "MainDB".
Everything works okay until I try to use automatic migration. After creating a new Managed Object Model version, and adding a new attribute to one of the entities in the UserDB Configuration, I get an exception when adding the old version store (for the UserDB related store) to the store coordinator: 'Model does not contain configuration 'UserDB'.' I can find no hits for this error on Google. Anyone out there using multiple stores with Configurations? Anyone have an idea what I might be doing wrong?
The stack looks like this:
objc_exception_throw
-[NSManagedObjectModel isConfiguration:compatibleWithStoreMetadata:]
-[NSStoreMigrationPolicy sourceModelForStoreAtURL:metadata:error:]
-[NSStoreMigrationPolicy(InternalMethods) _gatherDataAndPerformMigration:]
-[NSPersistentStoreCoordinator addPersistentStoreWithType:configuration:URL:options:error:]
-[MyAppDelegate persistentStoreCoordinator]
This looks like a bug with migration+configurations. I was able to work around the problem by going through the same motions and passing nil for configuration when calling addPersistentStoreWithType. The migration happens, and then I can make a new persistent store coordinator and add the stores again with the proper Configuration string arguments.
This is the second configuration related bug I've run into. Not a well tested feature apparently.
I had the same problem. The fact pattern was identical and the error message the same. It turned out, however, to be the result of my own mistake.
Let's say the old model was Blah.xcdatamodel and the new Blah 2.xcdatamodel. I had started making changes to Blah before realising my mistake and creating Blah 2. I then used my version control system (Git) to revert to the old Blah and then recreated Blah 2. Everything looked right. But I must have done something wrong in the reversion process, because when I thought to double check that Blah.xcdatamodel in my current project folder was really the same as Blah.xcdatamodel in the project folder I used to build the previous version of the app (fortunately I always keep a zipped archive of the project folder for each released version as I don't fully trust version control systems), I found that they were in fact different, albeit that they looked identical in XCode. The file size was different, for instance.
I substituted the old Blah into my current project folder, and lo and behold it all went perfectly, without any need for the workaround described by Ken.
I am not saying that Ken had necessarily made a similar mistake, but if you do encounter this message it is at least worth confirming that the model you are migrating from is REALLY the model that was used to create the data in question.
