            JSF - Validation error in 1 component, leads all others in the form to fail
            Asked 2021-Jun-15 at 14:11

            Hey to all in the forum

            I use JSF Mojarra implementation, version JSF 2.2

            I need desperately a help on this.

            1. I have a snippet of my page.
            2. I have a custom component "example_result.xhtml" used in the page.
            3. I have my BackingBean.java Be aware please that this code is not the real code I made. If you run it, it will be very ugly maybe because I deleted all the css classes and I kept only the hot stuff I need to show you my problem.

            Everything is inside 1 form.

            The 5 "h:selectManyCheckbox" (in my code I have 8 or 9)

            In the form I have 5 "h:selectManyCheckbox" which are using values in the "value" attribute for different cases (javaFrameworks2Values, javaFrameworks3Values,...), and the "f:selectItems" use arrays of "SelectItem" (javaFrameworksSelectItems2, javaFrameworksSelectItems3...) created for these different cases, just to make some examples for me to understand how all the selectOne and selectMany components work. The ideas for this, about different cases were taken from these links: "https://stackoverflow.com/tags/selectonemenu/info" and "https://mkyong.com/jsf2/jsf-2-checkboxes-example".

            After I have 2 commandButtons

            1 for submit, and 1 for reset the values.

            Display the values

            After I display the results of the values of the "h:selectManyCheckbox" via the "example_result.xhtml".

            You can see the 4th "h:selectManyCheckbox" that is the only one different, because it has the attribute "required" with the attribute "requiredMessage". With it there is a "h:message" to display the validation error.

            In the BackingBean (which is Spring Bean, but it works perfectly good - sorry I don't want ejbs 3.x), I have initialized:

            1. The values of the SelectItems and
            2. The values of the "value" attribute, where the values of the "h:selectManyCheckbox" will be stored to be displayed later. [The code is completely castrated, to make it readable snippet].

            When the page is rendered, I select checkBoxes (e.g. the 2 last, because the 2 first are initials) from all the "h:selectManyCheckbox". When I say that select from all, I mean it. And from the 4th with the "required" attribute. I try in the buttons (see in the code) the "Effort 1", or "Effort 2", or "Effort 3" (in the "f:ajax" in the buttons) and the result outputs in the last part are displayed and updated like a candy. Without any problem. To achive this with the composite component I googled and tried a lot. But I made it.

            Then it comes the time to try the 4th to see the validation error of the "required" attribute.

            I select again from all as before, but not from all. NOT from the 4th "h:selectManyCheckbox" this time. I select nothing from the 4th "h:selectManyCheckbox" to ckeck the validator error message ("requiredMessage"). The result is: It displays the message of error (GOOD until now), BUT this time it does not update anything from the others "h:selectManyCheckbox" to the output results at the end, and it does not reset the values as well as it was doing before (when I selected from all and from the 4th as well).

            I understand that it says: as long as in the form the 4th failed with validation error, all the other "h:selectManyCheckbox" will not update the output results (something like wanting to fail all the others too).

            But what really happes here?

            1. It does not give the values to the "h:selectManyCheckbox", to be updated to the output?
            2. It gives the vales to the "h:selectManyCheckbox" normally, BUT it just not updates the output?

            The other efforts in the "f:ajax" in the buttons, are just efforts maybe to solve the problem but in these cases they don't even display the error message in the 4th case and of cource they don't update the other output results as well (again). But no message error as well.

            I don't know if the problem is clear to you. I can explain in the discussion better so I can clarify the situation better. [To be honnet it took me 1 and half hour to write all this thing]

            Thanks a lot in advance

            I will make 5 different forms with 5 set of buttons (submit/reset), to make escalate this problem, for 5 so much related components in the form.

            But my question is open: Why this is happening, what rule in JSF in this case is taking place and makes this situation. Anyone, comes with an explanation:

            • Thomas: this is a rule in JSF, or

            Regarding the error

            I'm assuming you have missing dependencies on your code generation class path. Once you update your question, I'll update my answer.

            Regarding jOOQ code generation support for @TypeDef etc.

            jOOQ won't support your generated composite types in generated code out of the box, you'll still have to add forced type configurations for that, possibly embeddable type configurations:

            Note that the JPADatabase offers a quick win by integrating with simple JPA defined schemas very quickly. It has its caveats. For best results, I recommend going DDL first (and generate both jOOQ code and JPA model from that), because it will be much easier to put your schema change management under version control, e.g. via Flyway or Liquibase.

            You are violating the JPA spec by accessing the persistence context in a lifecycle listener.

            See the JPA Specification 4.2 Section 3.5.2

            In general, the lifecycle method of a portable application should not invoke EntityManager or query operations, access other entity instances, or modify relationships within the same persistence context. A lifecycle callback method may modify the non-relationship state of the entity on which it is invoked.

            "a portable application should not" is the specification way of saying: Don't do that, anything might happen. Maybe the world ends.

            The fix is not to do that. Maybe be preloading the currently logged in user and reference it so you may access it in your entity listener and do not set a reference to the user, but simple store its id or similar.

            This is happening because there is no Transaction opened in DTO(object become detached). Wherever you have fetched the object from the DB call contractFile.getContract() so that the ORM framework loads the lazy-loaded object.

            Your test is a junit4-api based. But from your pom.xml you have junit5 dependencies.

            Removing jupiter dependencies should do the trick.

            Regarding cobertura, as you run on java 8 preferably you should migrate to JaCoCo as cobertura with java version higher than 7 is buggy.

            I think the Lombok generated hashCode method is causing an infinite loop as Movie references Authors, each of which references the same instance of Movie.

            You can probably confirm this by checking bytecode, or just ditch the @Data annotation and manually code equals and hashCode on Entities.

            Alternatively you should be able to break the cycle with an @EqualsAndHashCode.Exclude annotation on the movies property of Author - https://projectlombok.org/features/EqualsAndHashCode
