Hi!

From your pic, I don't see why this fails. Author is clearly mentionned...
Can you send me your XMI file please? I'd like to run some tests (I'll try to reproduce what you tried to do in order to better understand this issue).

Also, this may be related: you have a bidirectional relationship. It will throw a CircularDependency later when figuring out which class is to be generated first.

Here is the xmi file

Ok It seems to I can´t send xmi file with attachment so I paste de file
here:

http://www.omg.org/spec/UML/20110701" xmlns:xmi="
http://schema.omg.org/spec/XMI/2.1" xmi:version="2.1"
xmi:id="_0EfOwBnaEeWw3ro4S7dYeg" name="poc">

I can't import it because Modelio tells me it's not a valid XMI file... I'll do the same diagram to test it.

This I the one y probe in another modelio project:

http://www.omg.org/spec/UML/20110701" xmlns:xmi="
http://schema.omg.org/spec/XMI/2.1" xmi:version="2.1"
xmi:id="_DyhREBnfEeWw3ro4S7dYeg" name="poc">
































/uml:Model

The issue is caused by the bidirectional relationship (they're evil).

I don't exactly see why they cause this to fail, but it works with this version of your file:

We should not close this thread yet, I want to find out why this breaks in the EntityCreator.

[MathieuAA]

Ok I got it (easy as pie)!

Modelio, if there's a bidirectional relationship, doesn't set a "name" attribute to its association tag:

<packagedElement xmi:type="uml:Association" xmi:id="_0EfOyxnaEeWw3ro4S7dYeg" memberEnd="_0EfOxRnaEeWw3ro4S7dYeg _0EfOzRnaEeWw3ro4S7dYeg"/>

The error is due to the fact that we partly check if there's no error! An injected field should have been deduced when reading the extracted data, but as there was nothing to read, an exception was thrown.

I'm going to fix this ASAP.

Please let me know if using a unidirectional association works for you (I'll close this thread after the fix is pushed).

[MathieuAA]

I'm closing this as the bug is now noticed.
Feel free to re-open this thread if I did something wrong.

This is proof of concept I am playing with jhipster-uml because I will
start a project(at leas 25 tables) of collecting account and I had mapped
bidirectional relationships
but I can leave without these relationships.

So Thanks and I will around here.

If it does, then everyting's alright. If it doesn't then something's
clearly wrong.

JHipster manages bidirectional relationships just fine!

UML-y speaking, bidirectional aren't that good, that's why we decided not to allow them at all (they can cause lots of issues, and usually can be replaced by better designs).

You can just "convert" your bidirectional to unidrectional, and it everything should work great.
Don't hesitate to open a new thread if you have any question regarding your POC, we'll be happy to help.
