Column Filter Watermark is Not Showing

[kunoozdubai]

Since PrimeFaces 6.0.19 our code for column filter watermark is not working as below:

<h:form id="myForm">
<p:dataTable id="myTable">
<p:column id="column2" filterBy="column2">
<f:facet name="header">
<p:watermark for="@(#myForm\\:myTable\\:column2\\:filter)"
value="Watermark 2" />
<h:outputText value="Column2" />
</f:facet>
</p:column>

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

Before the version 6.0.19, our code is working well. I hope you can give us some tips on this.
