how do I refresh a table component after selecting and deleting one
or more rows ?
I'm using trinidad-1.1.6-SNAPSHOT. I've got a table component (eg
"<tr:table>"). As I select and delete one or more rows, looking at my
database, the delete operation is actually carried out successfully but
the page isn't being refreshed accordingly: the deleted rows remain
displayed.
Is there a way to delete rows, keep displaying the same page but just
refresh it, removing any deleted rows ?
Thanks.

Hello,
Even if the row is deleted in the database, maybe it still exists in the
DataModel, can you provide a small code snip of your bean please? Also, are
you using PPR or is it a full submit delete?

Thank you for replying.
The bean is session scoped and I'd like to keep it session scoped.

If you want to use PPR you can add on actionListener method following
lines to resolve the problem:
public void myAction(ActionEvent event){
// action code
RequestContext requestContext = RequestContext.getCurrentInstance();
requestContext.addPartialTarget(event.getComponent().findComponent("trTableId"));
}
and this action will refresh only tr:table with id="trTableId".

Thank you for the information.
I didn't have to use partialTarget; I , instead, added an "action"
attribute to my commandButton component to force page refresh.

I've removed the binding attribute from the table component.

Hello,
Add "table:discard_selected" as partialTarget, tr:table is a naming
container, and I don't think we have a children trigger detection algorithm
implemented yet.
Also, you should not keep a a bound component in session (using binding
attribute). I read that you want to keep the bean session scoped, so you'll
have to split it in two beans:
Bean 1: TableStateBean, session scoped, contains listOfSimpleBeans attribute
Bean 2: TableControllerBean, request scoped, contains a reference to
TableStateBean, component and discardSelectedRowHandler action listener
method. You can inject the state as a managed-property and maybe provide a
getListOfSimpleBeans() method that delegate the call to the tableStateBean
object so you don't have to change the page to reflect that structural
change.

I used "rowSelection" attribute o achieve that. I'm using myFaces +
Trinidad + Facelets; so my script is "xhtml". Here are parts of my
script including the start the table tag and the commandButton that
actually deletes selected rows :
<tr:table
id="table"
immediate="true"
binding="#{backingBean.component}"
emptyText="#{bundle['empty_text']}"
rowSelection="multiple"
allDetailsEnabled="true"
var="row"
rows="#{bundle['table_nr_of_rows']}"
value="#{backingBean.listOfSimpleBeans}"
rendered="#{!empty ackingBean.listOfSimpleBeans}"
verticalGridVisible="true"
horizontalGridVisible="true">
...
<tr:commandButton
id="discard_selected"
immediate="true"
text="#{bundle['button.discard_selected']}"
shortDesc="#{bundle['tooltip.discard_selected']}"
actionListener="#{backingBean.discardSelectedRowHandler}"/>
...
Here is the method called by the above commandButton using
"actionListener" attribute :
public void discardSelectedRowHandler(ActionEvent action)
{
UIXTable table = (UIXTable)getComponent();
Object oldKey = table.getRowKey();
for (Object rowKey : table.getSelectedRowKeys()) {
table.setRowKey(rowKey);
E row = clazzE.cast(table.getRowData());
row.setChecked(true);
}
// remove selected rows from the list
table.getSelectedRowKeys().removeAll();
// restore the old key:
table.setRowKey(oldKey);
}
I tried adding 'partialTriggers="discard_selected"' to "tr:table"; that
didn't solve my problem.

Ok so this is a PPR delete then, I assume you placed the delete button on
each row of the table? If so then you have to add a partial target on the
table to the button.

Thank you Mike.
I did update the dataTable's backing list as well as the underlying
database; I was able to monitor the delete operation using a debugger.
Still the page isn't refreshed unless I reload it completely using a
navigation rule that forces the page to reload. My application is built
in such way that forcing the page to reload completely using a
navigation rule would lead to some valuable data getting lost; I'd like
to keep the page as is and just refresh the table component to make it
reflect the actual state after deleting rows.
Note : the dataTable's backing bean is session scoped.

When you delete the row, you would also update the dataTable's backing
list. It won't matter what the scope of the list is.

What scope is the bean that populates the table?
If the bean is session or application scoped then once you've populated
the table that's it until a new session is created or you stop/start the
server.
In this instance I've declared mytable as request scoped, so when the
page is re-drawn the values method which goes to the database is called
as the bean is loaded.
This obviously results in more db traffic but at least the start of the
table is consistent with the underlying database.
Here may be other solutions but this works for me.
<tr:table emptyText="#{bundle['mytable_empty.message']}"
value="#{mytable.values}" var="row"
rows="#{mytable.totalRows}"
binding="#{mytable.table1}"

I'm using trinidad-1.1.6-SNAPSHOT. I've got a table component (eg
