Re: Grid Pagination and Performance
The Grid should only ever send a single page of data at a time. Let's get things clear... Are you using @Persist or java.util.List with your large dataset? To maintain scalability you should never coerce GridDataSource to List. Perhaps it's just your choice of language (persist & list) that was ambiguous or perhaps we've found your issue. I think some code might help better explain what you're doing.

Re: Grid Pagination and Performance
The grid needs the rowcount to know how many pages there are in total (eg page 1 of N). HibernateGridDataSource and JpaGridDataSource execute 2 types of queries. 1 to get the rowcount and another to get a single page at a time. In my opinion this is a scalable approach.
Re: Grid Pagination and Performance
@Thai, you can implement your own GridSource for better performance.

Re: Grid Pagination and Performance
Hi, You are correct that the current provided implementations of the GridDataSource (HibernateGridDataSource and JpaGridDataSource) will query for the total number of rows in the database and therefor can kill performance on the client side as well as on the DB side. Particulary if sorting and filtering is applied. The GridDataSource is only an interface so its up to you on how you decide to implement the getAvailableRows function. I may have another solution, I've written a small component library for Tapestry with a 'PagedGrid' in it. This is an extension of the supplied Grid component with a custom pager and a custom DataSource implementation which does not query for the total number of rows and will perform much faster with large datasets. The code can be found here: https://github.com/intercommit/Weaves And a demo is running here: http://intercommitweavesdemo.intercommit.cloudbees.net/grid/pagedgriddemo Good luck, Antal OriginalMessage >From: "Thai Tran" >To: "Tapestry users" >Sent: Wed, Nov 13, 2013, 03:54 >Subject: [SPAM] Grid Pagination and Performance > >Good morning everyone (it is morning here :D) > >According to official documentation >(http://tapestry.apache.org/current/apidocs/org/apache/tapestry5/corelib/components/Grid.html), > >we only need to set the rowsPerPage to turn the pagination on without >caring about the actual returned list 's size.

Grid Pagination and Performance
Good morning everyone (it is morning here :D) According to official documentation (http://tapestry.apache.org/current/apidocs/org/apache/tapestry5/corelib/components/Grid.html), we only need to set the rowsPerPage to turn the pagination on without caring about the actual returned list 's size.

Re: loop pagination - T5 Bootstrap
It's true the mixin does not support GridDataSource, probably should but it works OK for most things as is. To support really large collections the pagination component would also need to be rewritten since it displays a link per page and that would not work well for thousands of pages. The other thing that got lost in my conversion to Bootstrap 2 was the mixin that allowed infinite scrolling if javascript is enabled. Perhaps it's time for some updates.

Re: loop pagination - T5 Bootstrap
Sorry for my previous answer… I didn't realise that this tapestry-bootstrap mixin existed. After looking at the source here: https://github.com/trsvax/tapestry-bootstrap/blob/master/src/main/java/com/trsvax/bootstrap/mixins/Pager.java It seems to me that this mixin does not do 'true' paging since the source is a java.util.List. I realise that the client only sees a page of data at a time. But on the server, the entire List must be loaded into memory which may cause OutOfMemoryErrors for large collections. The GridDataSource (or similar interface that supports serverside paging) is the more scalable solution. Please correct me if I'm wrong… I only had a quick look through the source code.

Re: loop pagination - T5 Bootstrap
The only core tapestry component which supports paging is the grid. If you're rendering a table, then use a grid http://tapestry.apache.org/current/apidocs/org/apache/tapestry5/corelib/components/Grid.html If you'd an example of a custom paging, take a look at my gallery component in tapestry-stitch which supports next and previous pages... this could easily be tweaked for page 1,2,3 etc. http://tapestry-stitch.uklance.cloudbees.net/gallerydemo Note that my example uses it's own interface for paging (ie GalleryDataModel).

Grid Ajax Failiure with Pagination.
Hi,
I have created a simple that submits and ajax renders a form. This fails
with two causes. First my code
`
View <#>
Here is my backing java class
public class Teller {
@Property
@Persist
private String recipientId;
@Property
@Persist
private String recipientName;
@Property
@Persist
private String recipientAmount;
@InjectComponent
Zone searchTransactionZone;
@Inject
private Request request;
@Persist
@Property
private ArrayList transactions;
@Property
private Transactions transaction;
@Property
private BeanModel transactionGridModel;
@Inject
private BeanModelSource beanModelSource;
@Inject
private Messages messages;
void setupRender() {
transactionGridModel =
beanModelSource.createDisplayModel(Transactions.class, messages);
transactionGridModel.add("action", null);
transactionGridModel.include("dateOfTransactions","sendersName"
,"sendersStateCountry", "action");
transactionGridModel.get("dateOfTransactions").label("Date Of
Transaction");
transactionGridModel.get("sendersName").label("Sender's name");
transactionGridModel.get("sendersStateCountry").label("Sender's
state/country");
transactions=new ArrayList();
}
@Log
public Object onSubmitFromSearchTransactionsForm()
{
transactions=new ArrayList();
for(int i=0;i<10;i++)
{
Transactions a=new Transactions();
transactions.add(a);
}
return
request.isXHR()?searchTransactionZone.getBody():null;
}
}
and my POJO class
public class Transactions {
private String dateOfTransactions;
private String transactionId;
private String recipientName;
private String recipientPhoneNumber;
private String sendersName;
private String sendersStateCountry;
public Transactions()
{
}
public String getDateOfTransactions() {
return dateOfTransactions;
}
public void setDateOfTransactions(String dateOfTransactions) {
this.dateOfTransactions = dateOfTransactions;
}
public String getTransactionId() {
return transactionId;
}
public void setTransactionId(String transactionId) {
this.transactionId = transactionId;
}
public String getRecipientName() {
return recipientName;
}
public void setRecipientName(String recipientName) {
this.recipientName = recipientName;
}
public String getRecipientPhoneNumber() {
return recipientPhoneNumber;
}
public void setRecipientPhoneNumber(String recipientPhoneNumber) {
this.recipientPhoneNumber = recipientPhoneNumber;
}
public String getSendersName() {
return sendersName;
}
public void setSendersName(String sendersName) {
this.sendersName = sendersName;
}
public String getSendersStateCountry() {
return sendersStateCountry;
}
public void setSendersStateCountry(String sendersStateCountry) {
this.sendersStateCountry = sendersStateCountry;
}
}
Now if i do not include the t:model="transactionGridModel" and remove the
code from the render portion, the grid gets displayed. However if i place in
pagination then clicking the second page the grid data disappears. If i
refresh the page, the data is displayed again. What am i doing wrong ?
Kind Regards

Re: Calling fnStandingRedraw to retain the current pagination settings using javaScriptSupport.addInitializerCall
Thanks Paul! I was beginning to feel like the step child here!
I was able to work around the issue by setting the "bStateSave" parameter to
"true" in my JSONObject controlling my dataTable Options... This causes a
cookie to save the state of my datatable after any updates
(http://www.datatables.net/ref#bStateSave)
However, my original plan of attack is still not working and I know this
issue is going to come up again.
I believe you are right that I am using .addInitializerCall unnecessarily. I
was able to make a call using
javaScriptSupport.addScript("fnStandingRedraw();"); just like you suggested
however now I think the problem is in how I am setting up my javascript
file.
Here is the JavaScript that I placed in a separate file:
$.fn.dataTableExt.oApi.fnStandingRedraw = function(oSettings) {
//redraw to account for filtering and sorting
// concept here is that (for client side) there is a row got inserted at
the end (for an add)
// or when a record was modified it could be in the middle of the table
// that is probably not supposed to be there - due to filtering /
sorting
// so we need to re process filtering and sorting
// BUT - if it is server side - then this should be handled by the
server - so skip this step
if(oSettings.oFeatures.bServerSide === false){
var before = oSettings._iDisplayStart;
oSettings.oApi._fnReDraw(oSettings);
//iDisplayStart has been reset to zero - so lets change it back
oSettings._iDisplayStart = before;
oSettings.oApi._fnCalculateEnd(oSettings);
}
//draw the 'current' page
oSettings.oApi._fnDraw(oSettings);
};
Not really a js guy (yet) so I'm wondering if there is some sort of Tapestry
namespace that I should be to or something else i'm not seeing
Thanks!

Have you tried
javaScriptSupport.addScriptCall("fnStandingRedraw();");
instead? I'm not sure if fnStandingRedraw is in fact a simple javascript method
or a valid initializer.

Re: Pagination Component
Page has context, component has parameters. Component should NOT care nor know the page it is in, to promote real componentization. It is not the job of the component to decode the parameters from web, the page should do that. And then the page should forward the context as parameters to the component. The page can also contain lots of other state that the component is not interested of and the same component could be used from several pages that have different context encoding schemes. - Ville -- View this message in context: http://tapestry.1045711.n5.nabble.com/Pagination-Component-tp4455142p4456045.html Sent from the Tapestry - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org
Pagination Component
Short version of my question:
What is the best way to setup things from the context in a component.
I tried using:
Object onActivate(EventContext context) {
// Do stuff with context
}
But onActivate doesn't seem to get called on a component on a page. Is
there a different method to get the context from within a component on
a page?
--
Longer version of what I'm trying to accomplish, just in case I'm
overlooking some built in functionality:
I have an app that needs to display paginated data for several
different pages. So lets say we have pages named:
/tag
/author
/category
They may be called like this:
/tag/foo/1 (the first page of a list of items assigned tag foo)
/author/25/1 (list of items authored by author with id 25)
/category/15/1 (list of items assigned to category with id 15)
The first item in the context is the ID of the author, tag or category
and the second is the page to display.
My goal was to create a pagination component that could be used on any
of these pages. So I was going to use onActivate on the page to get
the first context item (the id) and onActivate in the component to get
the second context (the page number). The page would handle the db
lookup and simply pass a list of all possible items to the component.
So the page would be responsible for getting the right list of items,
but all the logic for what objects to display on a particular page
would be in the component.
The two problems I've run into:
1. I can't seem to get the EventContext from within the component as
onActivate doesn't appear to be called on the component. I could get
it in the page and simply pass it to the component, but then I have
pagination code in the page which is what I was trying to avoid.
2. The component still needs to know page it is on and has to grab the
first context item in order to render the links to the other pages
using a page link. What I want is something that says: "Give me a link
to the current page and let me just change the last context item to
build a new page link."
Thanks for any suggestions.

Re: Regarding Pagination
Hi Sarav, Tapestry has Grid<http://tapestry.apache.org/tapestry5.2-dev/tapestry-core/ref/org/apache/tapestry5/corelib/components/Grid.html> but it cannot be customized to your particular case. There is Loop<http://tapestry.apache.org/tapestry5.2-dev/tapestry-core/ref/org/apache/tapestry5/corelib/components/Loop.html>, which can be customized in whichever way you want but it does not have pagination support. And finally there is PagedLoop<http://www.chenillekit.org/chenillekit-tapestry/ref/org/chenillekit/tapestry/core/components/PagedLoop.html> (not a core component) which have flexibility of loop and supports pagination too. regards Taha On Thu, Apr 21, 2011 at 2:36 AM, sarov saravanan wrote: > Hi, >Can any one provide me some examples of how to use > pagination(customized) in tapestry which full fill the following use case. > > - The page should contain list on items (each item has price, detail of > item and a link). > - whole page is displayed as a table and row which has few nested tables > and row inside it. > ex: xxx > > - I need a customized pagination to display the items: > ex: < PREV > 1 | 2 | 3 | 4 | > 5 > NEXT> > > which may be completely in separate table with different background colors > etc. > > Any help will be appreciated. > > Thanks! > > with regards, > Sarav > >

Hi all, I have a grid component with pagination in place. When I navigate through pages it takes awhile, so I was trying to give some feedback to the user by displaying an ajax loading gif. Albeit, I have no idea on how to do that, so I would appreciate if anyone could give me some pointers. Regards.

Re: pagination
If you look at the source parameter of the Grid, it is a GridDataSource object. You can bind a List to the source parameter, and Tapestry takes care of converting the list to a GridDataSource, but for large result sets from a database, you really want to use the GridDataSource interface, because it supports sorting and pagination in the database.

Does it retrieve all the data from the database and then does the pagination on the clientside or does it retrieve a page at a time from the database?

Pagination component for Tapestry4
Hello!
I'm working on one project with Tapestry 4 which makes heavy use of
paginated lists. They are at least 10 lists of different items in project.
This paginated lists have coulumns, optional filter and sorting upon some
columns.
I though of this in this way:
Application service returns a list of domain objects. Each domain object can
have tapestry component implemented. i.e. :
Class CustomerBean {
String firstName;
String lastName;
String phoneNumber;
//getters, setters, constructor
}
CustomerBeanComponent:
Template:
Specification:
Now PaginationComponent should take the List and iterate over
this list with rendering of it's body component. This is similar behaviour
like For component but I would need pagination, filters and columns in
PaginationComponent.
Can you give me some guidelines how to implement this component and do you
think is it possible at all?
Thanks!

Re: Grid Pagination And onActivate()
I think the problem is that you have persisted the category name, but not the
list of news articles that the grid is using, so when the second page is
requested, no data is available to display.
Try either
a) adding @Persist to your list of data items your grid is displaying, or
b) load the list of data items within onActivate.
Also, if you use onActivate, it is also a good idea to pair it with
onPassivate, as follows:
public String onPassivate() {
return currentCategoryName;
}
If you do that, you could probably even ditch the @Persist tag on the
currentCategoryName field, as the activation context is passed around in the
url.

Scott

using @Persist("flash") instead of @Perisist or
remove @Persist and set tapestry.suppress-redirect-from-action-requests to
true. It not a good way.see

Grid Pagination And onActivate()
Hello!
I have component witch takes one parameter and based on it
shows Grid component.
In page Archive, I have :
public class Archive
{
@Persist
private String currentCategoryName;
public void onActivate(String currentCategoryName) {
this.currentCategoryName = currentCategoryName;
}
}
In Archive.tml:
So when you go to www.example/archive/news page
you'll get grid showing articles from news category.
Problem:
When you click on page number, i.e. 4 you'll get :
"There is no data to display."
message, and URL will be www.example/archive
When I go back to www.example/archive, 4th page will show.
Is there any way to fix this?

Re: How to implement Pagination in T5
You'll need to create your own component, a cross between Loop and Grid.

Hi Bill,
This is a good idea, will give it a try, thanks.

Re: t5: Hibernate resultset with pagination
Hi Angelo, I achieve custom paging for anything that uses a tapestry
loop (or anything that needs a list per page) starting with this
abstract class:
public abstract class PagingResults
{
protected int _page;
protected int _resultsPerPage;
public PagingResults (int resultsPerPage)
{
_page = 1;
_resultsPerPage = resultsPerPage;
}
public List getCurrentPage () throws Exception
{
List pageOfResults = getResultsStartingAt( (_page - 1) *
_resultsPerPage, _resultsPerPage);
return pageOfResults;
}
public void incrementPage ()
{
if (_page < lastPage()) _page++;
}
public void decrementPage ()
{
if (_page > 1) _page--;
}
public void toLastPage ()
{
_page = lastPage();
}
public int lastPage ()
{
return
(int)Math.ceil((double)getTotalResults()/(double)_resultsPerPage);
}
public void reset ()
{
_page = 1;
}
public int getPage ()
{
return _page;
}
public int getResultsPerPage ()
{
return _resultsPerPage;
}
public abstract List getResultsStartingAt (int start, int
numToGet) throws Exception;
public abstract long getTotalResults ();
}
This class' getCurrentPage() method returns a "sublist" of the total
list for use in the loop, etc. Subclasses of this define the
getResultsStartingAt() and the total number of results. I usually
define subclasses of PagingResults as simple inner classes of my
page/component classes where the services I need are injected.
I have a companion component to this:
public class Pager
{
@Parameter (required = true)
private PagingResults _pagingResults;
@Inject
private Messages _messages;
@Inject
private ComponentResources _resources;
void onActionFromToFirst ()
{
_pagingResults.reset();
}
void onActionFromToPrevious ()
{
_pagingResults.decrementPage();
}
void onActionFromToNext ()
{
_pagingResults.incrementPage();
}
void onActionFromToLast ()
{
_pagingResults.toLastPage();
}
public String getPagerInfo ()
{
String s = "";
int startInd = (_pagingResults.getPage() - 1) *
_pagingResults.getResultsPerPage() + 1;
long endInd = (startInd + _pagingResults.getResultsPerPage() -
1 > _pagingResults.getTotalResults()) ?
_pagingResults.getTotalResults() : startInd +
_pagingResults.getResultsPerPage() - 1;
s = startInd + "-" + endInd + " " + _messages.get("of") + " "
+ _pagingResults.getTotalResults();
return s;
}
public boolean getOnFirstPage ()
{
return _pagingResults.getPage() == 1;
}
public boolean getOnLastPage ()
{
return _pagingResults.getPage() == _pagingResults.lastPage();
}
}
The template for this Pager component is simple:
http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd";>
http://tapestry.apache.org/schema/tapestry_5_0_0.xsd";>
${pagerInfo} ${message:first}
|
<
${message:previous.abbrev}
|
${message:next}
>
|
${message:last}
In the page/component that uses all this I have a loop (typically)
with source="pagingResults.currentPage". The around the list I place
the pager component which takes the same PagingResults object as a
parameter.
Note this is not setup for Ajax interaction, just standard action
links (Http gets).
Cheers,
Bill

Re: t5: Hibernate resultset with pagination
not sure what you are trying achieve exactly paging, table, all can be simply generated even without grid but you'll need to print each column manualy, or dig deeper and use beanModel your self Davor Hrg On Mon, Sep 1, 2008 at 3:32 AM, Angelo Chen <[EMAIL PROTECTED]>wrote: > > Hi, > > I have a need to display some Hibernate resultset with pagination, but I > can't use T5's grid. any hint how to do this in T5? thanks. > > Angelo > -- > View this message in context: > http://www.nabble.com/t5%3A-Hibernate-resultset-with-pagination-tp19247842p19247842.html > Sent from the Tapestry - User mailing list archive at Nabble.com. > > > - > To unsubscribe, e-mail: [EMAIL PROTECTED] > For additional commands, e-mail: [EMAIL PROTECTED] > >

contrib:TableView nested inside @For component causing Pagination problem
Hi, i am using an architecture like: <@For> <@MyTable /> The @MyTable is a component containing the TableView, TableColumns and the other Table components that are needed to render a fully fledged table. I have 4 Tables created by this @For component. Each table points to a specific source with e.g. 30 results. Setting the PageSize for each table to 10 this will produce a pagination for each table. When clicking in any table on the pagination links i recieve the result that each table paginates. This could be a construction problem but the components are mostly plain constructed. Anyone know this problem or has a solution to suggest how i can paginate on any table without effecting the other tables.

Re: Contrib:Table pagination and validation issue
I tried that, I'm pretty sure I missed something, but it did not work
for a reason (at least I believe that) my ImageSubmit buttons where
located around the register form. Even using Javascript
(document.forms['tableForm'].submit()) for some reason, some methods
like the remove all (its a table with checkboxes) did not update the
rows of the table, not marking the boolean property of the rows.
Gotta check that again someday :)

Re: Contrib:Table pagination and validation issue
Why don't you just have a separate form wrapping your table ? Seems like the

Re: Contrib:Table pagination and validation issue
Hi there Jesse! It's a master detail page: So I have a form to
register/update Seminars, and a Table with all the Seminars registred
so far.
As any form, it has validation on many fields. So, when I get a
pagination, and the user clicks on the navigation, the page renders
with errors from the validators.
I understand (or at least I believe I did) the reason for the submit,
once it submit the form, the values are preserved through navigation.
What I was expecting is that inside the table component it would clear
my delegate from any errors so no errors should be presented since I'm
not trying to persist my Entity...
I solved this on the onchage of the PropertySelection for instance, by
adding a few lines to my onRefresh method:
getDelegate().clear(); :D
For this issue with the Table component I removed every validator
bound to my form, and used manual validation on my listener:
public void onSave(){
validate(getDelegate());
}
private void validate(ValidationDelegate delegate){
//validate fields, and record errors on the delegate object
}
But would be real nice If the table component had a property like:
skipValidation="true/false" and if possible, somehow clear the
delegate / skip validation.
Anyway I've solved the issue no problems, thanks once again for all
support. I hope this demonstrates my scenario.

Re: Contrib:Table pagination and validation issue
Still stuck on this, I'm moving to the coding each validator on hand, dumping the automatic validation.

Re: Contrib:Table pagination and validation issue
Jesse I tried this, but I'm stuck in something Im sure its a dumb mistake from my self.

Re: Contrib:Table pagination and validation issue
Why don't you just separate the table from your other form and have two forms instead? Most of the form based functionality of the table is best realized when doing things like providing a "search" component or nesting form fields within table columns.

It simply made sure that on rewind you'd iterate over the same elements you had during render - it would throw stale link exception otherwise.

Search.page Search.html sdfs Error Component Search/table.tableFormPages.linkPage requires rendering support, but no PageRenderSupport object has been stored into the request cycle. This object is typically provided by a Body component. You should add a Body component to your template. location: classpath:/org/apache/tapestry/contrib/table/components/TableFormPages.jwc, line 82, column 45 77 78 79 80 81 82 83 84 85 86 87 Stack Trace: org.apache.tapestry.TapestryUtils.getPageRenderSupport(TapestryUtils.java:108) org.apache.tapestry.form.LinkSubmit.renderFormComponent(LinkSubmit.java:72) org.apache.tapestry.form.AbstractFormComponent.renderComponent(AbstractFormComponent.java:122) org.apache.tapestry.AbstractComponent.render(AbstractComponent.java:617) org.apache.tapestry.AbstractComponent.renderBody(AbstractComponent.java:434) org.apache.tapestry.components.ElseBean.renderComponent(ElseBean.java:45) org.apache.tapestry.AbstractComponent.render(AbstractComponent.java:617) org.apache.tapestry.AbstractComponent.renderBody(AbstractComponent.java:434) org.apache.tapestry.components.ForBean.renderComponent(ForBean.java:137) org.apache.tapestry.AbstractComponent.render(AbstractComponent.java:617)
