------------------------------------------------
Hi,
the use case is allowing user to select preffered sorting (i.e. sort column and
sort ascending properties) on page once and then have it stored until session
expires, without need to resort table every time he returns to this page.
Currently, I have such table:
<t:dataTable var="user" value="#{usersBean.users}"
sortColumn="#{sortColumns.users}"
sortAscending="#{sortDirections.users}">
<t:column sortable="true" defaultSorted="true">
<f:facet name="header">
<t:commandSortHeader columnName="name"
propertyName="name">
<h:outputText value="Name "/>
</t:commandSortHeader>
</f:facet>
<h:outputText value="#{user.name}"
styleClass="#{disablableStyles[user.disabled]}"/>
</t:column>
....(more columns here)
where userBean is in request scope, while sortColumns and sortDirections beans
- is session scope.
This works fine at first page access (sortColumn is null, sortProperty is
defined by defaultSorted attribute of column), as well as during resorts and
other actions on this page, until current view is not removed from server
session - i.e., user navigates to another page. And, after returning to this
page, sortColumn already not-null, and sortProperty is not set. This is part of
log in that case:
<html.ext.HtmlDataTable id="_idJsp21" ...
sortAscending="#{sortDirections.users}" sortColumn="#{sortColumns.users}"
sortColumnIndex="0" sortProperty="NULL" sortable="false" ...>
I think, I can attach simple test WAR file, showing up my problem, if it will
help. Currently, I've wrote extension of HtmlDataTable, with only overriden
method - protected DataModel createDataModel(), which gives desired behavior,
though I don't think that this is a general fix. Please, let me know, if
attaching it will help.
Thanks in advance,
Alexander.
