I have a form with a datatable inside it . In one of the columns is a button to delete that row. That button has a primefaces confirm dialog attached to it.
<h:form id="form" style="text-align: -webkit-center">
<p:dataTable id="preferenceConfigs" var="preferenceConfig"
value="#{preferenceManagementBackingBean.preferenceConfigs}">
<p:column style="width:6rem; text-align: center">
<p:commandButton update=":form"
title="#{msgs['common.delete.userpreference.button']}"
icon="fa fa-trash"
action="#{preferenceManagementBackingBean.invalidatePreferenceConfig(preferenceConfig)}">
<p:confirm header="Confirmation" message="#{msgs['common.dialog.preference.config.warning']}"
icon="fa fa-exclamation-circle" escape="false"/>
</p:commandButton>
</p:dataTable>
<p:confirmDialog global="true" showEffect="fade" hideEffect="fade" style="text-align-last: center">
<p:commandButton value="#{msgs['common.dialog.confirm.yes']}" type="button"
styleClass="ui-confirmdialog-yes" icon="fa fa-check"/>
<p:commandButton value="#{msgs['common.dialog.confirm.no']}" type="button"
styleClass="ui-confirmdialog-no" icon="fa fa-times"/>
</p:confirmDialog>
</h:form>
Everything works fine until I change the language on the page through a commandLink. They are located in a masterLayout file above this one:
<h:form id="generalSettingsForm">
<ul id="language">
<li><h:commandLink
action="#{languageSessionBean.changeLanguage('en')}" value="EN"
class="blgm_lSwitch" id="EN"/></li>
<li><h:commandLink
action="#{languageSessionBean.changeLanguage('nl')}" value="NL"
class="blgm_lSwitch" id="NL"/></li>
<li><h:commandLink
action="#{languageSessionBean.changeLanguage('fr')}" value="FR"
class="blgm_lSwitch" id="FR"/></li>
</ul>
</h:form>
public void changeLanguage(String language) {
locale = new Locale(language);
findCurrentFacesContext().getViewRoot().setLocale(locale);
}
This refreshes the page and displays the correct language. However pressing the remove button now automatically performs the action without any sign of the confirmation dialog. Only if I open another dialog (that is present in the JSF page) and return, will the confirmation shows its face again...
The dev console gives me the following error:
VM1391 components.js.xhtml:13 Uncaught TypeError: Cannot read property 'style' of undefined

Any insight?
After some more googling, it seems to be an issue with primefaces 6.2 with the following behaviour:
confirmDialog does not show, an error is logged on console (TypeError: this.jqEl is undefined)
This was fixed in 6.2.2. I cannot test this myself since all minor releases are for paying users only. As a workaround, I'll try a custom dialog. You can probably also use primefaces 7.0
