Tomahawk DataTable Sort Question - where/how is Sort Coded?
Can someone please help me to understand how to configure or code a column
sort for a Tomahawk datatable? Specifically, I'm not clear on how or what
sort method is called? Do the Tomahawk components take care of the sort for
me, or do I need to code the sort myself (and if so where)?
I think I have the JSP coded correctly:
<t:dataTable id="data" styleClass="scrollerTable"
var="providers"
value="#{searchproviders_bean.arrlist_providers}"
preserveDataModel="false"
rows="20"
sortColumn="#{searchproviders_bean.sortcolumn}"
sortAscending="#{searchproviders_bean.sortascending}"
preserveSort="true">
<h:column>
<f:facet name="header">
<t:commandSortHeader columnName="id" arrow="true" immediate="false">
h:outputText value="#{messages['sort_id']}" />
</t:commandSortHeader>
</f:facet>
<h:outputText value="#{providers.id}" />
</h:column>
<h:column>
<f:facet name="header">
<t:commandSortHeader columnName="category" arrow="true"
immediate="false">
<h:outputText value="#{messages['sort_category']}" />
</t:commandSortHeader>
</f:facet>
<h:outputText value="#{providers.category}" />
</h:column>
</t:dataTable>
'searchproviders_bean' is the backing bean, and 'arrlist_providers' is an
ArrayList. The ArrayList is initially sorted when it is retrieved from the
database. After the data is retrieved, I disconnect from the database. The
data in the ArrayList will be read-only (will contain search results list -
the data is not updateable.) When the data is displayed to the user, I
want them to be able to sort the data by clicking on the column headings.
I have also added the 'sortcolumn' and 'sortascending' properties to the
backing bean as strings with the appropriate getter/setter methods:
public class searchproviders_bean {
private ArrayList arrlist_providers;
private String sortcol;
private String sortascending;
...
The part where I am confused is how to implement the sort method. I know
that the ArrayList gets 'wrapped' by a DataModel object (though I only
understand this at a high-level), but I'm not sure how to configure or code
the sort? Does the Tomahawk DataModel implement the sort or do I need to
code the sort? If I need to code the sort, can someone please help me to
understand where to implement this method and provide any helpful code
examples?
BTW, currently, the datatable is displaying, but when I click on the column
headings, the data does not sort (but the arrows on the column header change
directions.) Also, I do have a datascroller connected to the datatable that
is working correctly:
Thanks
Tom

No, that's not possible.

Re: Tomahawk DataTable Sort Question - where/how is Sort Coded?
Posted by Sébastien Marin <th...@free.fr>.
I try to use the datatable sort.
Is it possible to make the sort on client side (no access server)?

Sort your data in getArrlist_providers depending on the values of
sortcol and sortascending.
Collections.sort(arrlist_providers, YourComparator) may sort the list.
