Prerequisites:

User Story:

Implementation:

datatable header

    <p:commandLink value="-" action="#{a.delete(var)}" />

delete method in bean

    model.getList().remove(sth);        
}

Outcome:

Outcome

When hovering over the commandLink its showing me this Uniform Resource Locator localhost/applicationname/#

Eclipse is giving me the Facelet Validator Warning Marker Syntax Error on this ExpressionLanguage Code #{a.delete(var)}

Question:

What am i missing in order to delete the row?

What was/is the scope of your bean? If it was request scoped, that explaines why it did not work with the pf button and does with the plain jsf one. By that change, you switched from using ajax to a non ajax call. — Kukeltje

Solution:

I have changed to commandlink from JSF (not primefaces) and got the Error, that my method shouldnt be void, but String after changing that and returning null it works...

public String delete(Something sth) {

    model.getList().remove(sth); return null; 
}
