Cryptic error message

1
replies

Image Text

I have recently come across the error message "Loops that Generalization relates are not permitted."

I am really struggling to understand what it is trying to tell me. It doesn't even appear to obey english grammar. I think it's to do with generalization loops, but beyond that I'm lost.

Could this error message be reworded / improved?

Thanks.

I do not want to show the Visibility (-,=,# and ~) on the attributes or operations for the current class diagram. I can not figure how to stop the Visibility (-,=,# and ~) from appearing.

Hi. I'm evaluating the Astah Pro Version.

I'd like to set a small description on mindmap nodes. Is it possible?

What about the descriptions of an imported MindMap from FreeMind/FreePlane?

Component diagram/draw multiple usages of a provided interface in the same diagram

4
replies

Hi, I have three components in a component diagram, each providing the same interface ("lollipop-bullet"). I also have a component which can USE this interface of each component. But I can only draw one "usage" line with the corresponding "lollipop-bracket" style. For the others, Astah says "this usage relationship already exists". How can I draw this? Is this scenario forbidden in UML, and if so, what is the recommended way? Thanks for any hints Ingo

Drag & Drop from class (actor) to Use Case

1
replies

I created a simple class diagram with 3 classes (Lecturer, Student, Exam). Then I created a Use Case diagram in the same project and would like to drag & drop the class Lecturer from the left panel (where all my classes from the project are listed) into the Use Case diagram but nothing happens.

I have used Astah before (about 2 years ago) and I remember that it worked back then.

If I copy the class from the class diagram, I can paste it into the Use Case diagram but this is of course not what I want.

FYI: Right now I am on a trial Astah Professional license (Version 7.0.0) on a Mac (I used to have a Windows PC though, is there something wrong with the Mac version or is drag & drop not possible anymore?)

Association between imported Java Classes

1
replies

I am using Astah Professional 7.1 to import a Java Project so I can generate the class diagram automaticaly.

But I have a little issue, there are some association relations (when one class depends of some other one via a method) that does not appear on the generated diagram, and I'm not sure if Astah can identify those relations for me. I am aware that those dependencies apear in the traceability map, but it would be usefull for me if I could have them in the class diagram.

Your request has not reached the server

replies

Hi there

We rebooted the server hosting Astah share this week and since then we've been unable to login. When the correct login credentials are entered the user receives the message

Your request as not reached the server

Please check if connection is ocrrectly established and reload the page.

If I use the browser debugger and monitor the traffic, when the login button is pressed I see a http request to http://astah:7080//messagebroker/amf

which receives a 404 response from the server.

How should I go about resolving this ?

thanks

50 Day Trial, But Actually Only 20 Day Trial

1
replies

Just curious, I am trying out Astah Pro trial version. On the Web site it says the trial is for 50 days, but on download the usage limit is only for 20 days. Not complaining, 20 days seems like a reasonable time limit. It might be a good idea if the Web Site stated 20 days.

Plugin tutorial page out

replies

Hi guys,

I am building a plugin for Astah and I was using the tutorial available in http://astah.net/tutorials/plug-ins/plugin_tutorial_en/html/index.html. However, this link is going to a 404 Error page now. Is it just some random error or the plugin development support is being discontinued? Hope the latter not to be true.

Thank you.

Error: "Cannot move an Execution Specification to its target"

1
replies

I keep running across a frustrating and annoying error when trying to edit sequence diagrams.

Supposing I have sequence diagram like this:

Image Text

And I want it to look like this, with Message2 starting from the execution specification resulting from Message1.

Image Text

I try to drag the beginning of Message2 to the execution specification above it on Lifeline2, and I get the following error message: "Cannot move an Execution Specification to its target."

Image Text

As far as I know, this is a perfectly valid thing to do, and this use-case occurs regularly when modifying/editing sequence diagrams. It makes it very difficult to modify large sequence diagrams as it forces either deleting and recreating messages, or moving portions of execution to a "dummy" lifeline temporarily.

So my question is: Is there a reason for this error? If not, can it be removed for this use-case?

Wrap text and resize blocks

2
replies

Is it possible for Block names to wrap so they can be resized? The block width on the diagram is fixed to the width needed to show the Block name on one line. I would like the blocks to be resized to a narrower width, but to do this the Block name needs to adjust to multi-line.

replies

I was working on a project and when I tried to save it, astah crashed. I have a fresh installation of astah, it was my first ever project. I searched if other people experienced the same issue, and I found a solution to their crash, you had to commentate a line out of the ini file: astah-com.l4j.ini (​Before)​ ​-Dsun.java2d.d3d=false (After) #-Dsun.java2d.d3d=false

But this didn't work for me. I hope i'm able to fix this.

Astah drawing bug

2
replies

I just installed Astah Professional to my Arch Linux computer. About a year ago I used version 7.0.0 to create a model for an assignment without any flaws. However, with both versions 7.0.0 and 7.1.0 (and both Oracle JDK 8b121 and OpenJDK 8b121) I now get a drawing bug.

When opening the .asta file I used last year (or trying to create a new model), whenever I open a class diagram everything gets repeated every 100x100 pixels or so. When using the scrollbars every such box scrolls independently, creating this weird output. When opening the menus and hovering over them the disappeared part gets drawn correctly, until I hover with the mouse over the model window, when everything gets redrawn incorrectly again. Only when minimizing the class diagram window and reopening it again, the output looks correctly, until I move my mouse over the window and the wrong output shows up again.

Has anyone experienced this before?
