modeler | A vuejs based BPMN modeler | BPM library

I am writing a code to read a local text file into my No Magic Cameo Systems Modeler. I am using Javascript Rhino for the same. But not getting any viable solution to read the text file.

I used Java's bufferedReader class but then I am getting the following error :

"org.mozilla.javascript.EvaluatorException: missing ; before statement (#25)"

Can anyone assist me in what I am doing wrong. I am fairly new to javascript .

Please advice how to transform the original dataset to the expected output as shown below on SPSS Modeler?

It is expected to merge the values of all rows shared the same ID No.

May I know how I can convert the data in SPSS Modeler as the image below?

I have read How to restructure data in SPSS Modeler? and tried Restructure but it did not generate format like "From_1", "To_1", etc.

Greatly appreciate any help/advice. Thanks a lot in advance.

When i redirect to the Edit.cshtml page, only the HttpGet seems to be working. The HttpPost is not working. Which means that when I make changes and click on the Edit button on the Edit form, the HttpPost Edit is supposed to be invoked to call the PUT API. But the HttpGet Edit is called instead... What have I done wrong?

The HttpGet to retrieve the existing info

I added odata to startup and model builder and I wanted to test if it works and return an OData so I updated the controller and changed it to "ODataController" and I make a simple HttpGet test the result but the URL: Text returns 404 not found Text return 404 not found and Text return a simple Array with json objects

This is my code

Startup.cs

I tried to build a drop-down list from the AspNetRoles table in register.cshtml and register.cshtml.cs but didn't get data from AspNetRoles in the register page.

I am writing a frontend/backend application. The frontend is an Angular 13 application. The backend is a combination backend API and administration web site. The backend has:

• Local Identity (including Identity scaffolding),
• Web API (for Angular frontend using Swagger bearer tokens),
• MVC view/controllers for side table administration.

The frontend needs to access API services. Login returns a token. The token is used to access the various services to maintain the application tables.

The backend .net 5 Core website reads and writes to a local SQL Server database. The database contains the Identity tables. The backend is also used to maintain the Identity tables using the scaffolding Razor pages. The backend maintains (basic CRUD) for a number of administrative tables. So, a user or an administrator logons via the scaffolding logon form using the same logon account that is used for the Angular frontend.

The problem is the login via PasswordSignInAsync is successful but User.Identity.IsAuthenticated is false. I use User.Identity in lots of places for name, roles and IsAuthenticated. I got a sense that User.Identity is supposed to happen automatically when using cookie authentication scheme. I added dual schemes, but that has not solved the problem. I have read through a number of questions per PasswordSignInAsync not working, but none seemed to help. The things I tried to solve the problem may have adversely affecting the outcome. I have read the source code of CheckPasswordSignInAsync and I do not see any setting of User.Identity. Not knowing what to do to get beyond this issue.

Please feel free to ask for any clarifications.

I’m showing my complete Startup.cs.

I just downloaded activiti-app from github.com/Activiti/Activiti/releases/download/activiti-6.0.0/… and deployed in tomcat9, but I have this errors when init the app:

Shared aggregation seems to express nothing more than a simple association. It is apparently a "modeling placebo" with no objective reason to use it (except in specific contexts where modelers have agreed between them on specific additional semantic).

Several sources claim however that shared aggregation would imply absence of cycles in the aggregation graph of instances. This would make aggregation a powerful tool in the domain of graph modeling.

But I couldn't find any evidence of those claims in the specifications. Did I miss some indirect evidence (e.g. interplay of several constraints)?

In their book The Unified Modeling Language Reference Manual, 2nd Edition, Booch, Jacobson and Rumbaugh claim about (shared) aggregation:

The distinction between aggregation and association is often a matter of taste rather than a difference in semantics. Keep in mind that aggregation is association. Aggregation conveys the thought that the aggregate is inherently the sum of its parts. In fact, the only real semantics that it adds to association is the constraint that chains of aggregate links may not form cycles, which is often important to know, however. (...) In spite of the few semantics attached to aggregation, everybody thinks it is necessary (for different reasons). Think of it as a modeling placebo.

Other rather well informed sources(e.g. uml-diagrams.org and several academic papers) keep the directed acyclic graph for granted as well.

The books is from 2004, based on UML 2.0. But most of this claim is still verified in the UML 2.5.1 specification. Shared aggregation is defined therein in very vague terms and without any objective advantage over a simple association (p.112):

Sometimes a Property is used to model circumstances in which one instance is used to group together a set of instances; this is called aggregation. To represent such circumstances, a Property has an aggregation property, of type AggregationKind; (...)
...
shared : Indicates that the Property has shared aggregation semantics. Precise semantics of shared aggregation varies by application area and modeler.

Another clause about aggregation prevents some special cycling situations (p.200):

An end Property of an Association may only be marked as a shared or composite aggregation if the Association is binary and the other end is not marked as a shared or composite aggregation.

I have however not found any evidence that "chains of aggregate links may not form cycles" in the general case. I also did not find other properties such as transitivity and anti-symetry which could allow to infer the absence of cycles.

Is the claim by the UML inventors now obsolete? Or did I miss something in the current specs that would allow to derive this statement ?
