Hi

I am using the Listbox to show the records from the database as follows

    <div width="96%" sclass="sectionpadding">
                            <div sclass="floatright">
                                <paging id="pagenavi"
                                    pageSize="@load(vm.pageSize)" sclass="floatright"
                                    style="padding: 5px 84px 3px 12px;" pageIncrement="1"
                                    detailed="true" autohide="true">
                                </paging>
                            </div>
                            <div sclass="clearboth"></div>
                        </div>
                        <separator />


                        <listbox id="" mold="paging"
                            paginal="${pagenavi}" sclass="mylist"
                            selectedItem="@bind(vm.selectedItem)"
                            model="@load(vm.dataSet)">

And also, on double click of the listbox item , i am using some other page on the same container and in that page i have go back button to return to Listbox page.

Here user would like to show the same page no on clicking go back button. Here is the sample use case.

  1. A zul page xxxx.zul contains Listbox
  2. User Moves to 3 Page page.
  3. Double click any of the item to open yyyy.zul
  4. yyyy.zul opens in the same container.
  5. in yyyy.zul, we have go back button.
  6. On clicking go back button in yyyy.zul, we need to show the again xxxx.zul and also the listbox should point to 3 page.

So how we can move page in list box pro grammatically ?

Will work fine when you do on button click. Try to change when is page is load , as said , put the code in @afterCompose command in MVVM

Isn't the code now in aftercompose in the fiddle?

Hey Senti.

Could this fiddle help you out?
As you can see I set the totalPages also to a calculated field.
Then the paging element will not go into error.

http://zkfiddle.org/sample/2j8njg9/1-setPaging-in-aftercompose

Edit :

Oke I see the problem. Try this :

this.pageSize = FHSessionUtil.getDesktopHeight() - 1;
activePage = this.searchClaim.getActivePage();
totalSize = (activePage + 1) * pageSize;
this.selectedClaim = null;
pageination.setTotalSize(totalSize);
pageination.setActivePage(activePage);
fetchRecord();
fetchTotals();

Edit2 :

Senti,

Now let us dig deeper. Copy the Page class and put it in your project (same FQN)
Class can be found here : https://github.com/zkoss/zk/blob/master/zul/src/org/zkoss/zul/Paging.java

Now, in the setActivePage put at the first line a logging for the totalsize.
I'm pretty sure the total size isn't what it should be but, beter to know what we get.

Greetz chill.

So even in MVVM, we still need to use to component wire and set the active page properties. Please note in the above example,. pageination is wire component from zul ?

Senthilchettyin ( 2015-02-05 08:46:22 +0800 )edit

I still don't see a reason to mix MVVM and MVC here... am I missing something?

@Senthil: It is very well possible and there is absolutely NO need to mix MVC/MVVM for this case (i.e. no need to @Wire any component).

Please see this running example showing a paging listbox with detail navigation (after double click) and a back button restoring the previous active page.

No for me it's no bug, your paging is still empty when you try to set the active page. Just one question, I don't know that use of paging (only use it with the totalsize, pagesize and activepage binded). How do you set the total elements of that paging component?

chillworld ( 2015-02-05 06:25:32 +0800 )edit

I'll explain the error. You set active page to 1 (what is page 2 in fact) and your total size is equal or below the pagesize, So ZK throws the error that you can't go to page 2 as there is only 1 page.

Here is the Code

    Zul

<paging
pageSize="@bind(vm.pageSize)" id="pageination"
detailed="true" totalSize="@bind(vm.totalSize)"
activePage="@bind(vm.activePage)" />

View Model

@Wire("#pageination")
private Paging pageination;


this.pageSize = FHSessionUtil.getDesktopHeight() - 1;
activePage = this.searchClaim.getActivePage();
totalSize = (long) 0;
this.selectedClaim = null;
//The following line gives error message 
pageination.setActivePage(activePage);
fetchRecord();
fetchTotals();

Another example in different search page

     <paging

    activePage="@bind(vm.activePage)"
    sclass="floatright" pageIncrement="1" detailed="true">
