p:datatable filter: cannot validate component with empty value

Is there a way to filter a p:datatable column by clicking on the text inside and making this text the filter ?

In other words, if I click on a session ID, I would like the datatable to filter this column by the clicked ID, as if I had entered it manually in the filter above ?

I am using Primefaces 6

UPDATE

This is my complete Datatable with the suggested solution:

<p:dataTable id="tablealltx" var="transaction" value="#{pastTxModel.txList}" paginator="true" rows="20" sortBy="#{transaction.createdDate}" sortOrder="descending" resizableColumns="true">             

    <p:column filterBy="#{transaction.session}" filterMatchMode="contains">

        <f:facet name="filter">
            <p:inputText id="myFilter" value="#{transactionXmlController.currentFilter}" onchange="PF('alltxform').filter()" />
        </f:facet>

        <p:outputLabel value="#{transaction.session}" ondblclick="document.getElementById('alltxform:tablealltx:myFilter').value = this.innerText;PF('tablealltx').filter()" >        
    </p:column>
</p:dataTable>

When I double click on the session, the value is entered in the filter text box, but the filtering itself does not work. Nothing happens.

I am using TomEE 7.0.1

Solution Copy Paste from Jasper:

The data table in your question doesn't have a widgetVar set to tablealltx, so PF('tablealltx').filter() will fail. You can test it by entering PF('tablealltx') in your browser's JavaScript console.

I was able to achieve this by setting widgetVar="myTable" to the data table, using a custom filter field, replacing the cell contents with p:outputLabel (which has ondblclick) and JavaScript it all together:

<p:column headerText="Session" filterBy="#{transaction.session}" ...>
    <f:facet name="filter">
        <p:inputText id="myFilter"
                     value="#{myBean.myFilter}"
                     onchange="PF('myTable').filter()"/>
    </f:facet>
    <p:outputLabel value="#{transaction.session}"
                   ondblclick="document.getElementById('myForm:myTable:myFilter').value = this.innerText;PF('myTable').filter()"/>
</p:column>

For better readability, here's the ondblclick:

var filterId = 'myForm:myTable:myFilter';
document.getElementById(filterId).value = this.innerText;
PF('myTable').filter();

You could replace p:outputLabel with a simple h:outputText, but in that case (assuming you are on JSF 2.2+) you need to add the namespace xmlns:a="http://xmlns.jcp.org/jsf/passthrough". Now you can use:

<h:outputText value="#{transaction.session}"
              a:ondblclick="..."/>
