I am using primefaces(6.2) datatable, while using column filter I am observing a weird behavior, though all the columns (with outputText, inputText) retain the object value, columns with 'selectOneMenu', 'selectBooleanCheckbox' not retaining the object value and returning null, false. Issue occurring only while performing the filter and filer returns no rows, if the filter returns at least one row everything looks normal and all columns are behaving normally. please find below code snippet that I am using to troubleshoot, I really appreciate any inputs to resolve this issue.

return lstContact;
}
public void setLstContact(List<Contact> lstContact) {
this.lstContact = lstContact;
}
}
If I just enter 'X' in second column(First Name) filter and remove 'X' all values at first column (Salutation) are gone.
