use selectManyButton with elasticSearch on primefaces

Question

I'm trying to use the component selectManyButton for updating the datalist but it doesn't work. When I use selectOneButton, it works correctly.

The method I'm using to filter is an ElasticSearch query.

This code works without error:

<p:selectOneButton value="#{carEsBean.carEs.carburant}">

<f:selectItem itemLabel="Diesel" itemValue="Diesel" />
<f:selectItem itemLabel="Essence" itemValue="Essence" />
<f:selectItem itemLabel="Hybride" itemValue="Hybride" />
<p:ajax event="change" update="selectedCarsList" />
</p:selectOneButton>
<p:dataList value="#{carEsBean.carsQuery}" var="car" type="definition"
id="selectedCarsList" paginator="true" rows="10" >

and when I want to use this, it's not working:

<p:selectManyButton value="#{carEsBean.carEs.carburant}">

<f:selectItem itemLabel="Diesel" itemValue="Diesel" />
<f:selectItem itemLabel="Essence" itemValue="Essence" />
<f:selectItem itemLabel="Hybride" itemValue="Hybride" />
<p:ajax event="change" update="selectedCarsList" />
</p:selectManyButton>

The query I'm using is :

if (StringUtils.isNotBlank(carEs.getCarburant())) {
    if (query == null) {
        query = QueryBuilders.boolQuery().must(QueryBuilders.matchQuery("carburant", carEs.getCarburant()));
    } else {
        query = query.must(QueryBuilders.matchQuery("carburant", carEs.getCarburant()));
    }
}

I'm using primefaces 6.2, jsf 2.3 on Springboot

PrimeFaces (or even JSF) does not know **anything** of elasticsearch (nor about springboot). Try splitting down your problem. Create a unittest for the elastic search stuff or see if you can create a pure jsf example (without elastic search) that has 'the same problem'...

i already make this test and they work correctly when i set one value , but can i set multiple value on the same Atrribut ?I think not, because the last value overwrites the previous ones — Cesar, Dec 23 '19 at 10:39
Can you set multiple values in java to a `String`? Or do you use something different then? So effectively your question is purely a PrimeFaces `selectManyButton` one of which the PrimeFaces showcase has a working example.. https://www.primefaces.org/showcase/ui/input/manyButton.xhtml — Kukeltje, Dec 23 '19 at 10:44
so for this i dont have to edit my querry ? because they work correctly with selectonebutton — Cesar, Dec 23 '19 at 10:48
What exact type is `#{carEsBean.carEs.carburant}`? What does 'is not working' mean? — Selaron, Dec 23 '19 at 10:56
That is a pure elasticsearch/java thing. If you can populate an array/list in with the `p:selectManyButton`, JSF and PrimeFaces have done their thing. Whether you need to change the query when switching from a String to an arrayt/list needs query changes is a pure elasticsearch thing. That is narrowing down problems (=approaching this as a developer) — Kukeltje, Dec 23 '19 at 11:00
@Selaron yes my type is #{carEsBean.carEs.carburant} , they not work i mean the datalist was not uploaded — Cesar, Dec 23 '19 at 11:04
`#{carEsBean.carEs.carburant` is not a **TYPE** it is a value expression in EL. String, ArrayList, Boolean those are types... And 'datalist not uploaded' is not a developer analysis. — Kukeltje, Dec 23 '19 at 11:10
@Kukeltje i mean my Atrribut String type # {carEsBean.carEs.carburant}, and datalist not updated sorry — Cesar, Dec 23 '19 at 11:12
How many instances of String can be stored in a property of type String by a select***Many***Button? — Selaron, Dec 23 '19 at 11:15
@Selaron in my example,i need to set a 3 values in selectManyButton — Cesar, Dec 23 '19 at 11:17
@Kukeltje yeah this not show a error , the only think changed is the datalist was not updated (but with selectOneButton is updated) — Cesar, Dec 23 '19 at 19:34

the carEsBean.carEs.carburant this part should be a list of Strings List<String>, not a String to be able to use SelectManyButton

Check the showcase for more info https://www.primefaces.org/showcase/ui/input/manyButton.xhtml
