type argument is not within bounds of type-variable Q #849

See Issue #254 |

Could you provide example sources for HidaBez and HidaBezGruppe? There is already a Querydsl test case with a similar domain https://github.com/querydsl/querydsl/blob/28810ccd6d4a9ba519c4b361c232653891dd2d8e/querydsl-apt/src/test/java/com/mysema/query/domain/Generic4Test.java Feel free to use this as the basis. #254 is related to Path class usage, but the error message might be the same. |

What's the best way to paste code without losing the special symbols? Is there wiki formatting for code, or an attach button somewhere? |
|
|
Here is a guide for github markdown https://help.github.com/articles/github-flavored-markdown |
|
@tpischke What's the type of HidaBezGruppe.bez in the sources? And how do you generate the code? |
|
|
Our generation plugin
|
|
Thanks, could also provide the execution element for the querydsl-maven-plugin in your project? |
|
|
I added now a test with Hibernate model based code generation also got What JDK do you use? |
|
Standard JDK 1.7. Why is the generated code different than 2.8.2? 2.8.2 was patched to fix exactly this problem, but now the old pre-2.8.2 behavior is back... |
|
Which 2.8.2 fix do you refer to? And what is your exact JDK 1.7 version? #254 is a different issue. |

}How does your version look like? |

Aha! Forgot to mention that we use the aspectj 1.7.4 compiler with source level set to 1.7. That is probably the issue. I refer to patch in Issue #254 |
|
I'm working on simplifying the generic usage in our domain model. It is horrible, so I'm not surprised that it is too much for QueryDSL + AspectJ compiler to handle. Will post again with simplified model. |
|
I was now able to reproduce the JDK 1.7 compilation issues. |
|
Great! |
|
Ok, got it compiling after removing all the superfluous generics. |
|
|
Ok, I will still fix this also on the Querydsl side. |

Released in 3.4.2 |

Regression in 3.4.1. Worked correctly with 2.8.2
[ERROR] generated-sources/model/QHidaBezGruppe_Last.java:[28,35] type argument model.hida.QHidaBez is not within bounds of type-variable Q
In 2.8.2, the following was generated in QHidaBezGruppe_Last
In 3.4.1, we only get:
Note replaced greaterthan lessthan with braces, since they don't render properly
Which does not compile with the error mentioned above.
