cellTable paging: server side query return wrong result using JPA
hi all:
follow the well know expense example, i see the following code in
Report.java:
@SuppressWarnings(unchecked)
public static ListReport findReportEntries(int firstResult,
int maxResults) {
EntityManager em = entityManager();
try {
ListReport reportList = em.createQuery(
select o from Report
o).setFirstResult(firstResult).setMaxResults(
maxResults).getResultList();
// force it to materialize
reportList.size();
return reportList;
} finally {
em.close();
}
}
i setup my environment exactly the same as expense does, however, everytime
the query return the first *maxResults *result. and never return the entries
beyonds the* maxResults.*
*
*
for example, at client side, my cell table using a SimplePager, with the
range 0-8 each page. say i have 80 entities in table, whatever the
firstResult and maxResults is, the search result is exactly the *0-8* in the
table. never show the others beyond *8*.
i debug for days yet still not luck. anyone can give some clues where is
wrong?
i use datanucleus JPA 2.1.4 and GWT 2.1 with Mysql 5.
thanks very much.

Re: Editor Framework Questions
hi : i'm new to the Editor too, but to my understand, Editors are for displaying/editing data directly from server side. for example you have data in your DB, you retrieved it as Entity in your web server side, by using Editor you can edit and/or display it at client side with ease. seems like a map from data/object to UI. without Editors, you have to parse the data from server side, creating UI to display/edit the data at client side. i know the Expense example using editor. i didn't get through it though. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: cellTable paging: server side query return wrong result using JPA
another question, the JPQL query seems rarely function well, i checked if i use: ListPerson rl = em.createQuery( select o from Person o ).setFirstResult( startIndex ).setMaxResults( maxCount ).getResultList(); my first query using the startIndex=0; and maxCount=35, it return 35 objects, the next time i invoke this method using startIndex=0 and maxCount=55, it still return 35 objects. what's wrong with it? -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

how to make table auto-extend, just like new google group UI 's content view?
hi all:
if you are using the new version of google group now, you must be feeling
that it's much much more comfortable than the old ones, it's just like a
desktop app with wonderful user experience.
i'm more interested in the auto-extend cellList, i.e. if the scrollbar hit
the end it display more content automatically, i'm trying to add this
feature to my own application, now i can impl the auto-extend function
follow by the cellList example, but stuck at the UI layout:
.scrollable {
height: 100%;
width: 100%;
border: 0px solid #ccc;
text-align: left;
position:relative;
}
g:HTMLPanel styleName={style.listView}
a:ShowMorePagerPanel addStyleNames='{style.scrollable}'
ui:field='pagerPanel' /
a:RangeLabelPager ui:field='rangeLabelPager' /
/g:HTMLPanel
the HTMLPanel still has outer HTMLPanel which wrap it, it's style is:
.content {
position: relative;
border: 1px solid #ddf;
overflow-y: auto;
overflow-x: hidden;
}
public class ShowMorePagerPanel extends AbstractPager
{
...
private final ScrollPanel scrollable = new ScrollPanel();
/**
* Construct a new {...@link ShowMorePagerPanel}.
*/
public ShowMorePagerPanel()
{
scrollable.addScrollHandler(...);
}
public void setDisplay( HasRows display )
{
assert display instanceof Widget: display must extend Widget;
scrollable.setWidget( ( Widget ) display );
super.setDisplay( display );
}
...
}
but seems there are two scrollbar, the outer one and inner one, the outer
one can scroll but the inner one can not.
my question is how to set the style, and let it behaves like google group?
thanks.

Re: how to make table auto-extend, just like new google group UI 's content view?
yes i said in my question i followed the cellList example, but they are different: cellList has a fixed height which make it scroll. my question is how to make the table *occupy the center page* just like google group center view does, rather than a fixed height. do i make it clear? -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Editor Framework Questions
There are two driver types - SimpleBeanEditorDriver to work with simple bean-like objects - RequestFactoryEditorDriver integrated with RequestFactory and RequestContext objects The pros are best described in the goals: http://code.google.com/webtoolkit/doc/latest/DevGuideUiEditors.html#Goals The cons are, from my perspective, as with any generic framework: a generic algorithm theoretically should be a bit slower than if you hand-code your bindings between UI controls and backing data objects. However, I haven't seen any performance problems since I started using RequestFactoryEditorDriver: it works great.

TreeViewModel and AsyncDataProvider
I have a 3 level CellBrowser. Everything is working fine using a
ListDataProvider except that it's too long to grab the data from the server.
So I want to use the AsyncDataProvider to fetch only the data that the user
actually needs. Basically what I want to do is when the user selects the
level1 value, the level2 provider executes a RPC call to get the level2 data
based on the selected level1 parent. The problem is that the onRangeChanged
method is called before the onSelectionChange, so when the RPC call is done
the level1 value is still null. What is the proper way to use
AsyncDataProvider to grab the level2 data depending on the level1 selected
value?
public class SportTreeModel implements TreeViewModel, Handler {
private AsyncDataProviderLevel1Node level1Provider;
private AsyncDataProviderLevel2Node level2Provider;
private final SingleSelectionModelLevel1Node level1SelectionModel;
// In the construtor I create these objets
// In getNodeInfo I link a cell with the data provider and the selection
model
@Override
public void onSelectionChange(SelectionChangeEvent event) {
Object src = event.getSource();
if (src == level1SelectionModel) {
Level1Node level1 = level1SelectionModel.getSelectedObject();
((MyAsyncLevel2Provider)
level2Provider).setLevel1(level1.getValue());
}
}
}
Thanks
