BlockUI is not triggered when trigger is in a p:column

Question

I am using buttons in a p:datatable and they are triggering a p:blockUI (PF 6.0)

When located in the footer of my datatable, the button does trigger the blockUI. When moved into a column, it does not trigger it

BlockUI

<p:blockUI block="blockPanel"
    trigger="myForm:myTable:myButton myForm:myTable:myButton2">
            Loading..<br />
    <p:graphicImage name="images/loading_blue.svg" />
</p:blockUI>

Datatable

<p:panel id="blockPanel">
    <h:form id="myForm">
        <h:panelGrid columns="1" cellpadding="5">
            <p:dataTable id="myTable" value="#{modelBean.myList}" var="entry">

                <!-- Some data -->
                <p:column headerText="Name">
                    <h:outputText value="#{entry.name}" />
                </p:column>

                <!-- Does not work -->
                <p:column style="text-align: center">
                    <p:commandButton id="myButton" actionListener="#{bean.method()}" />
                </p:column>

                <!-- Works -->
                <f:facet name="footer">
                    <p:commandButton id="myButton2" actionListener="#{bean.method()}" />
                </f:facet>

            </p:dataTable>
        </h:panelGrid>
    </h:form>
</p:panel>

Why ?

The following workaround did not work for me:

<p:commandLink ... onclick="bui.show()" oncomplete="bui.hide()">
...
<p:blockUI widgetVar="bui" />

i know that it is sound very weird but try `trigger=" :myForm:myTable:myButton , :myForm:myTable:myButton2"` — Yagami Light, Oct 21 '16 at 20:11
did you add `blocked` to make a condition how the blockUi will appear and disappear — Yagami Light, Oct 24 '16 at 08:18
It did not work. However when I put simply blocked="true", it is always blocked. So the problem still comes from the trigger. — Tim, Oct 24 '16 at 08:57

I had found that question too - but it is already 3 years old... I don't know what got fixed in PF6 with regards to this issue — Tim, Oct 25 '16 at 08:24

The workaround from the other p:commandLink question did not work for me, I assumed it was part of the same problem. I'll update my question — Tim, Oct 25 '16 at 10:43

As a workaround, I used pe:blockUI:

What I mean : You don't have any value in your datatable. Put it one, you can create a backingBean return one value and add property value=#{myBean.value}. Also you have data on you datatable ! Test it

There are values in the DataTable. I left them out to focus on the problem. I updated the first post.. – Tim Oct 24 '16 at 08:13
