Paging table in BC

Hello,
can help how paging data in view entity and reflect it in ADF page.
I use entity and view entity to build data control (BC)
sample,
table have 15 records show on page ADF 5 rows
first page first 5 rows.
second page second 5 rows.
third page third 5 rows.
can help me thank you,

Hi.
the use of scroll does not mean you get all the records at once
For example, if a collection in the data control contains products and the iterator range size is 25, the first 25 products in the collection are displayed on the page. If the user scrolls down, the next set of 25 is displayed, and so on.
here is the doc http://docs.oracle.com/cd/E21764_01/web.1111/b31974/bcdcpal.htm#BABIFIBI

Sorting of table by TreeByNestingTableColumn

Hi everyone,
does anybody know if it's possible to enable sorting of the table where TreeByNestingTableColumn is used?
I could not enable clicking on the TreeByNestingTableColumn header - there is no onAction event defined and no mapping for parameters.
Sorting by other columns works perfectly with use of recursive sort of nodes.
Did I missed anything?
Thanks!
Best regards,
Nick

Hi Valery,
In my case the column contains not only images, but also text (I've got too many rows in the table and deep hierarchy of the tree - keeping only images is incomfortable with "paged" table). Clicking on the column header should sort e.g. alphabetically items on the same level.
Best regards,
Nick

Problem in writing the URL in Paging tag

This is the part of my code which actually does paging
<table width="544">
<pg:paging url="AdminPolicies.jsp?catid=${catid}">
<c:forEach var="Material" items="${mat}" varStatus="row" >
<pg:item>
<tr class="${row.index % 2 == 0 ? 'even' : 'odd'}"><td id="line"><strong><a id = "link" href="Admin/${Material.location}">
<c:out value="${Material.name}" /></a></strong>
Author: <c:out value="${Material.author_fname}" /> <c:out value="${Material.author_lname}" />
<c:out value="${Material.description}" />
Submitted By: <c:out value="${Material.submitter}" />
Date Submitted: <c:out value="${Material.date}" />
<%
if(loggedUser.isInRole("admin"))
%>
<div id="right"><a href="Admin/EditMaterial.jsp?catid=${Material.catid&scatid=${Material.scatid&name=${Material.name}&submitt=EditMaterial&no=no ">Edit</a> | <a href="Admin/EditMaterial.jsp?catid=${Material.catid}&scatid=${Material.scatid}&name=${Material.name}&delete=delete&noscatid=noscatid " onClick="return confirm('Are you sure you want to delete this Material');">Delete</a></div>
<%
%>
</td></tr>
</pg:item>
</c:forEach>
<pg:index>
<pg:page><%=thisPage%></pg:page>
<pg:nextPages><a href="abc.com">ABh</a></pg:nextPages>
</pg:index>
</pg:paging>
</table>
My problem is that in url="AdminPolicies.jsp?catid=${catid}
I am not getting the value of catid. i.e ${catid} comes out to be blank when I click on the link of page 2.
catid is the value on my page which I get from request object.
Can u tell me how can I get the catid value in URL tag.
Also placing the caid in this <%=catid%> way does not work.
Waiting for your reply,
Aniketh

Hello Can anyone put some light on this post...

Want to sort tables inside a complex mechanism, what can be the approac

I have a situation where first we are fecthing some ids(list of say version ids using hibernate form database)
then keeping those list of data in a Pager Object(Paging mechanism displays 100 rows per page out of complete sa 100 or so.)
This pager class does two things one takes whole list of ids (Collection of version_id).
(Every time based on search criteria it changes. For searching in hibernate values are hardcoded. Want modification with minimal changes as many things are interrelated here.)
and other thing it checks no. of contents based on that displays data per page(100 here).
It means stores all data from database and send it oage by page.(First thing to notice)
Next all this is getting stored in Report page where it searches other column names based on ids(version_id) the other column names are getting changed for different requests so what we do is take all other columns collectAllExtraFields(this is also getting changed everytime based on what is getting searched.)
Now all this is getting accumulated while displaying but as we know what to display we hardcoded all fields required to display based on search. But all fields are searched based on the id fetched from database first time which Pages is storing.
like this
Search for product user information & retrun results in the form of a paged table for components used by specific product
ComponentVersion versionObj = versionHandler.getComponentVersion(versionId);
String CAUsers = ctHelp.getCAUsersSection(versionId);
tableBody = tableBody + ((i%2 == 0) ? "<tr class='table_banded_row' valign='top'>" : "<tr class='table_row' valign='top'>");
tableBody = tableBody + "<td class='table_data'>" +

this is getting called by Report.jsp to display.
As this is getting changed everytime its called form classes not used in jsp directly i think.
Now original objective is to sort all these displayed columns.
If user clicks on any of the column name everything sholud get sorted on that basis.but sholud not call databse for same again by using same id and mapping with any new column name this sholud be done. Paging mechinasm to be used as it is if possible without major changes.
i don't know where to start with as started looking on this code just 2-3 days back only.

Sorting and paging - two separate issues. Tackle them separately.
Sounds like you've given yourself a problem by embedding all this logic in the JSP itself. That makes a mess. If you had a front controller servlet that could help you out that would make the page easier.
I think your difficulties are caused by a bad design.
Do your sorting by putting data structures into request scope on the page and make the sort requests back to the page itself. Rearrange the data, then display.
The paging issue is separate. Set the fetch size and have a server-side component that helps with the paging.

How to print data from database

Hi,
Assume that the HR web application contains a JSP page that displays the employees in paged table. The employees table has a link "Print" witch suppose to print al the records from database NOT only the data that is shown in the current page.
For example:
The employees.jsp displays a table of 15 rows, paging links (first, previous, 1, 2, 3, next, last) and "Print" link.
When the user click on Print link or button , it should popup the print dialog then print all the records of employees from the database NOT only the 15 that are shown in current page.
What do I tried??
I do display all employees records in one JSP page (printableEmployess.jsp) and divide them to tables, where is every 35 record in one table. But this methodology is not efficiently, because one company in my application has 20,000 records so the JSP page is too huge .
Kindly help me to fix this problem.

The put it bluntly: the browser can only print what it has received from the server. If you want to print everything, you have to send everything. If you don't want to do that, you'll have to stick to the multiple pages and then the user has to print every page himself.
If this is a really big problem for you, then you'll have to concider alternative solutions, like a Java client application that can connect to your server to retrieve the data and then print it using the Java printing API. That puts the problem outside the browser, but the user will have to have java installed on his machine.

9iAS JSP/Tag Library Help needed

Info: We have 9iAS 9.0.2.0.0 running on Sun Solaris (Sparc). I have been to Sun class for JSP/Servlets (SL-314) and have an Iterator custom tag that works fine in Tomcat 4.0. I am compiling on a Windows NT machine using Ant and JDK 1.3. I then deploy using Oracle Enterprise Manager (web interface to 9iAS) and use the Deploy WAR option. The only examples I can find that came with 9iAS use JSP 1.1 Taglib code and they work. Am I missing something, or does 9iAS (9.0.2.0.0) not fully support JSP 1.2 / Servlet 2.3, specifically the 1.2 tag library API?
Any help would be appreciated...
Code Snippets from failing JSP:
<%@ taglib uri="hr/taglib" prefix="hr" %>
<hr:iterator id="empdata" listName="employeeList">
<li><jsp:getProperty name="empdata" property="name"/> (<jsp:getProperty name="empdata" property="depth"/>)</li>
</hr:iterator>

Sorry techie_sudhanshu .. i was away for the month with no internet access and just got back... here's an example :
<display:table name="CUSTOMERS" pagesize="10" id="customer" sort="list" defaultsort="3" requestURI="/customer.do?submit=Search" class="model">
     <display:setProperty name="paging.banner.placement" value="both"/>
     <display:setProperty name="paging.banner.some_items_found" value=""/>
     <display:setProperty name="paging.banner.one_item_found" value=""/>
     <display:setProperty name="paging.banner.all_items_found" value=""/>
     <display:setProperty name="paging.banner.no_items_found" value=""/>
     <display:setProperty name="paging.banner.onepage" value=""/>
     <display:setProperty name="basic.msg.empty_list"><center>No Record(s) was found.</center></display:setProperty>
      <display:column title="Name" sortable="false"><c:out value="${customer.name}"/></display:column>
      <display:column title="Address" sortable="false"><c:out value="${customer.address}"/></display:column>
</display:table>The line where `<display:setProperty name="paging.banner.placement" value="both"/>` was specify solves your problem. By setting it to BOTH it will appear above and bottom of the paging table.

Performance difference between page and scroll

Hi experts:
What is the technical difference between paging and scrolling, especially as pertains to database access and performance? The scenario would be a table result in a view where 200 results exist for a query. A scrollable table would show all results, while the paging table would show 10/20 per page. Is the database selection the same for both approaches? Or is the paging approach going to make more trips? If there are trips - how does the UI know how many pages should be presented? Is one or the other a better approach for data which is not existing in CRM system?
regards,
bill.

If you look at the servlet translated from a JSP, you'll see these lines:
Object page = this;
pageContext = _jspxFactory.getPageContext(this, request, response,
null, true, 8192, true);
_jspx_page_context = pageContext;
application = pageContext.getServletContext();So page is simply an alias for this.
And PageContext is analogous to ServletContext but please notice, it's not the same or a replacement; application is the implicit reference to ServletContext and not pageContext. There is no equivalent of pageContext in servlets.
Please note that the page scope doesn't refer to the page object but to the pageContext. Therefore, what Manivel said above
page is used as a scope with in one jspisn't correct.

Do Flex has rich set of components(UI or non-UI)/feature?

Hi all,
i have some question about flex and hope you could help me:
1. is there any good collection of UI controls/components ???(e.g. datetime picker, paging
      datagrid..)..i found some free/opensource sample, but they buggy, ugly or
      non-flexible(e.g. http://code.google.com/p/flex-component-library/, http://www.adobe.com/cfusion/exchange/index.cfm?event=extensionDetail&loc=en_us&extid=1784 022)...
   2. is there any 'large'/long-running vendor selling flex UI components? in some project i use
        .net, there are infragistic, telerik...etc ...
        but for flex, i search the web, seems no such software company...
    3. could you recommend some books for writing good custom UI components?
        (in case there is no vendor/no suitable controls, i need to write my own)..
     thank you.
ppk luk

Hi,
as the build-in component is far from enough and i don't want to build and maintance these components by myself.
so i am looking for a more comprehensive set to UI components, both free or commercial are ok.
but, what i meet is that i can't find such components in the market!!
so, i wonder if i can rely on Flex to build a usable application for in house use.
as i said b4, there is no:
1. datetime picker
   2. paging table
3. keyboard mnemonics
4. text field / area no redo/undo
5. no titled border (i.e. a control to surround another control (canvas?) and give a text description)
i know there are many many other fancy control available in the web, but i can't (or i don't know where to) find these common UI component.
as i am new to flex, i don't want to build all the controls i needed, i would rather buy them (of course at reasonable price!).
again....anybody know such kind of popular/well-know UI component suite ? (especially with the above controls i mention)
thank you.

Issue with ADF table range paging and sorting

Hello,
We have a requirement to support pagination in ADF tables. For this, we have made use of Range paging access mode in the view object level. The paging works perfectly fine with this. But we have another requirement of letting the user do a sort on the table (Yes!! The paginated table). The sort should be applied on all rows in the db and the control should return to the first row.
Applying sort as it is provided by the fwk, sorts the records in the obtained range only. So we have over ridden the Sort listener in Managed bean for this and are able to acheive the sorting of all rows through a AM method call. We are seeing a problem after this. If the sort action is applied to the key attribute then the previous and next range navigation works fine. If the same action is applied to non-key field, then some times (yea!! This is not consistent) the next set is not fetched.
Here is the code snippet that is called on Next navigation:
Map<String,Object> pfScope = AdfFacesContext.getCurrentInstance().getPageFlowScope();
Object objPageNumber = pfScope.get("pageNumber");
int pageNumber = 0;
if(null != objPageNumber)
pageNumber = new Integer(objPageNumber.toString()).intValue();
BindingContainer bindings = BindingContext.getCurrent().getCurrentBindingsEntry();
JUCtrlRangeBinding view = (JUCtrlRangeBinding)bindings.getControlBinding("GeDmRequestVO");
int iRange = getTable().getAutoHeightRows();
int currentPage = view.getIteratorBinding().getNavigatableRowIterator().getRangeStart()/(iRange + 1);
System.out.println("Before " + view.getIteratorBinding().getNavigatableRowIterator().getRangeStart());
System.out.println("Current : " + currentPage);
System.out.println("Page Number : " + pageNumber);
System.out.println("Range : " + iRange);
System.out.println("Value : " + iRange*(currentPage + pageNumber));
view.getIteratorBinding().getNavigatableRowIterator().scrollRange(iRange*pageNumber);
System.out.println("After " + view.getIteratorBinding().getNavigatableRowIterator().getRangeStart());
Although, the new values are not refreshed in the table, the SOPs for before and after print the proper range sizes. And as I mentioned above, the above code works perfectly fine if there is no sort applied or when key attribute is sorted.
Would appreciate your help on this regard with navigation after non-key attribute sort.
Thanks,
Chitra.

Hi Chitra,
Can you specify some links to implement RangePaging.....We need to implement pagination.If possible can you share the code or specify the steps how you achieved it.
Thanks

WD Table: Repositioning Paging Buttons in Table Footer

How can we identify the table/SQL to skip & instantiate it later so the logical DB will not being lag far behind.
Thank you.

Hi,
Best way to find SQL is to mine the current archive log getting applied on standby and check for the SQL, you might not get the exact SQL, but you will get the object which is getting updated.
Or
You can use AWR report from logical standby of this time to find the update statement which is resource extensive.
There is no way to find the exact SQL on primary which is causing the issue on standby.

ADF 11.1.1.2.0 paging in table. How to do this?

Hi,
I am using ADF 11.1.1.2.0 with ADF 11g.
I am looking to do paging in various tables that I have created frm the VOs. I do see that older ver. of ADF had a direct and a declarative approach to do paging but in ADF 11.1.1.2.0 does not seem to have that support.
What is the simplest way to achieve this. Basically user should see a next and previous button/link and it will fetch the next/previous set of records, without creating too many objects.
Pls guide.

There is no direct solution in adf rich faces for page navigation like if was present in 10g. You can do this if you use trinidad tables.
Paging is done implicit when you scroll down/up the adf table. If you don't like it you can try to implement it yourself.

Grand total in Pivot Tables with Paging

I could help with this issue please
when we apply paging PivotTables there a way to show Grand total all pages, and I've noticed that the Grand total vee only when the last page or show all results at once.
For me it is important to see the Grand total on every page.
Thanks in advance for your cooperation

If you're not talking about printing, then you can do this:
1) Instead of using the same pivot table that you created for details to also display the Grand Total, first paginate the pivot table. Look here:
Re: Pivot table
In your pagination, break your pivot table in groups such that you can see a small enough chunk without having to scroll too much.
2) Now that you have a manageable size pivot table, create the Grand Total as another pivot table. Take out all the attributes that break the total in detail and leave only what will give you the Grand Total.
3) Add this pivot table to the bottom of your detail pivot table in step 1. This will give you the grand total right underneath each page of your detail pivot table without having to go all the way to the end of the report.
