Primefaces datatable, nested conditional row coloring - css

Question

I'm using PF 3.4.1 and JSF.
I would like to have a conditional selection of the css rowclass depending on two conditions:
One style should be for objects that are disabled, and one for objects that are expired.
I was able to put this two conditions in the same time, but, obviously, this cause a redundancy of css classes. I would like to have an overwrite of the classes in order to have predominance of the css class of disabled objects on expired objects.
Should look like this structure:
if (expired){
if (disabled){
return css1;
}
return css2
}
However, that is the code:
<p:dataTable id="results" var="utente" value="#{searchController.userList}"
paginator="true" rows="10"
rowStyleClass="#{user.expDate le user.currentDate ? 'rowdatatable3' : 'rowdatatable2'} #{user.enabled eq 'FALSE' ? 'rowdatatable1' : 'rowdatatable2'}"
paginatorTemplate="{CurrentPageReport} {FirstPageLink} {PreviousPageLink} {PageLinks} {NextPageLink} {LastPageLink} {RowsPerPageDropdown}"
rowsPerPageTemplate="10,25,50">
rowdatatableX are css styles.
With this code, results have always rowdatatable2 or rowdatable1 and never the 3rd option.
My idea was something like this:
rowStyleClass="#{user.expDate le user.currentDate ? #{user.enabled eq 'FALSE' ? 'rowdatatable1' : 'rowdatatable3'} : 'rowdatatable2'} "
..but it doesn't work.
Please help to find a solution. Thanks.

Answer 1

Try writing a method in your Bean (or transient method in user entity) that compares 2 dates expDate and currentDate
public boolean isExpired() {
return getExpDate.before(getCurrentDate);
}
If user.enabled is of type boolean skip the FALSE comparison. Since your table variable is utente you should use it! Your expression should look like that
"#{utente.expired ? (utente.enabled ? 'rowdatatable1' : 'rowdatatable3') : 'rowdatatable2'}"
so:
IF expired AND enabled -> 'rowdatatable1'
IF expired AND disabled -> 'rowdatatable3'
IF NOT expired -> 'rowdatatable2'
