Yet another attributes on steroids gem. Heavily inspired by Virtus and Values which both are great projects. The purpose of this project is to have a small & simple codebase and minimum number of features. For a more complex solution I strongly recommend Virtus which I'm happily using in production.

QUESTION
I am working on extending a Vue.js frontend application. I am currently inspecting a render function within a functional component. After looking over the docs, I had the current understanding that the render function within the functional component will return a single VNode created with CreateElement aka h. My confusion came when I saw a VNode being returned as an element in an array. I could not find any reference to this syntax in the docs. Does anyone have any insight?
...ANSWER
Answered 2021-Jun-15 at 15:37It seems this was implemented in:
https://github.com/vuejs/vue/commit/c7c13c2a156269d29fd9c9f8f6a3e53a2f2cac3d
This was a result of an issue raised in 2018 (https://github.com/vuejs/vue/issues/8056) , because this.$scopedSlots.default() returned both a VNode or an array of VNodes depending on the content.
The main argument was that this is inconsistent with how regular slots behave in render functions, and means any render function component rendering scoped slots as children needs to type check the result of invoking the slot to decide if it needs to be wrapped in an array
So Evan comments on the issue thread here, explaining that this.$scopedSlots.default would always return Arrays beginning v2.6 to allow for consistency, but to avoid breaking changes for how $scopedSlots was being used, the update would also allow return of an Array of a single VNode from render functions as well.
QUESTION
Hey to all in the forum
I use JSF Mojarra implementation, version JSF 2.2
I need desperately a help on this.
- I have a snippet of my page.
- I have a custom component "example_result.xhtml" used in the page.
- 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:
- The values of the SelectItems and
- 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?
- It does not give the values to the "h:selectManyCheckbox", to be updated to the output?
- 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

Answered 2021-Jun-15 at 14:11After a lot of discussing with the only person who wanted to help to my issue here (and I thank him @WoAiNii for this a lot), I decided to post my solution:
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
- is a JSF bug, or
- this happens in these cases, or... whatever...,
I will be glad to read it here so I will learn better, and others to will learn from these ideas of yours. Thanks a lot

I have a model form that creates a new job entry, and on submission, I need an invisible field job_time_estimation to be set to a sum of 'service_stats_estimate_duration' values from ServiceItemStats objects associated with the JobEntry by a many-to-many relationship when submitting the form.
For example, if in my NewJobEntryForm I chose two existing ServiceItemStats objects that have service_stats_estimate_duration values 60 and 90, on submission, I want a value 150 to be saved in that JobEntry object's job_time_estimation attribute.
I tried doing this using aggregation by defining a save() method in the model but I am getting an error "name 'serviceItemStats' is not defined".
I am not sure if I am going about this the right way. Any help would be appreciated.
