Component doesn't show the validation/error message just an icon - validation

Question

I have an autocomplete with validator. If the validator fails, it doesn't show the error message. It is shown only in a tooltip.
<h:panelGroup styleClass="form-group">
<div class="col-md-3">
<p:outputLabel value="#{labels['product_console_ins_management_company']}"
for="managementCompany" />
<p:panel rendered="#{empty saveProduct.initShowId}" >
<div class="form-control">
<p:autoComplete id="managementCompany"
required="true"
requiredMessage="#{labels['product_console_ins_management_company_validation']}"
value="#{saveProduct.product.company}"
var="b" itemLabel="#{b.description}" itemValue="#{b}"
completeMethod="#{saveProductConsoleController.completeInstrumentFactory}"
process="#this" scrollHeight="300" forceSelection="true"
converter="components.SimpleTypeBeanCollectionArrayConverter">
<f:validator validatorId="managementCompanyValidator"/>
<f:attribute name="boundList"
value="#{domainData.instrumentFactoryList}" />
</p:autoComplete>
</div>
</p:panel>
<br />
<p:outputLabel
rendered="#{ not empty saveProduct.initShowId}"
value="#{saveProduct.product.company.description}" />
<p:message for="managementCompany" display="icon" />
</div>
</h:panelGroup>

Answer 1

This is exactly what you tell it to do and effectively your question is not related to the validator or the p:autocomplete.
From the PrimeFaces documentation (read it, use it, it IS usefull)
Display Mode
Message component has three different display modes;
text : Only message text is displayed.
icon : Only message severity is displayed and message text is visible as a tooltip.
both (default) : Both icon and text are displayed.
This can also be seen in the PrimeFaces showcase for the message(s) component
So if you want different behaviour, choose a different value ('text' or 'both')
