Re: Hibernate: 1-to-many -- struggling
Duncan Krebs wrote: Hey, Here are my two cents. The biggest obstacle with Hibernate is figuring out how to correctly map the stupid collections and relationships that are modeled in your object model. I did not take the time to look at all your code but maybe this will help you out: The mapping is one obstacle, the other one is dealing correctly with the dreaded m:n relations, there is a huge lack of good documentation in this area, I hope the next release of Hibernate in action will resolve that... Hibernate is not a toy but it is harder to grasp in some areas than a straight database approach via jdbc. I am just wondering all the time when I am banging my head again for hours against some weirdness which was caused mostly by a mistake of mine, due to lack of understanding / documentation in a certain area, if there cannot be a sane middleground somewhere. now it is getting really off topic ;-)
Is there anybody out there?
Hi, Could you please vote this JIRA issue, so it can be given some priority? It has not even been assigned to anyone :-( http://issues.apache.org/jira/browse/MYFACES-522 Thanks.

Hi,
you must remove the immediate=true form your submit button!
this skips the updatemodel phase.

The Backing Bean looks like
package ca.gc.nrc.iit.toml.frontend;
//import javax.faces.model.*;
public class RateCourseBackingBean {
private String evaluation = test;
public String submit() {
System.out.println(this.evaluation);
return submit;
}
public String cancel() {
return cancel;
}
public String getEvaluation() {
return evaluation;
}
public void setEvaluation(String evaluation) {
this.evaluation = evaluation;
}
}
It works so far but the System.out.println() in submit() only ever
prints test on the console.
And I don't know why.
Did I make a mistake in the nesting of the tags of the JSF-page?
(What is the official nesting of elements? The JSF-Spec does not seem
to state what an empty JSF-page should look like and how the elements
are to be
nested.)
Do you have any idea where that mistake is?
Thanks

Re: Providing bugfix: Firefox body onload= tag - Re: x:inputCalendar - popup hidden by other elements
Thanks Paul, but could you please open a JIRA issue with the problem
and upload the patch there? Then this will be tested :-) We have to
keep the bugs under control...

Hi,
this is definitly a bug. So, here I provide the solution. Can someone
test and commit the files please?
I saw the mail in the dev list from Zhong Li:
---
I found how it happened. I have onload on body tag, even with simplest
one, something like, body onload=alert('loading');
...
Then the inputCalendar doesn't work, can't popup. so weired.
---
Since he had the same problem I checked the JavaScript behaviour in
Firefox and debugged a little bit...
This problem occures because the old JavaScript is executed in Firefox
before the body tag onload is set during the render phase.
So this variable var jscalendarOnloadBackup = window.onload; is only
set to undefined and never with the old onload script.
To solve this problem I rewrote the load script as a function in the
popcalendar.js and this function is then called just before
jscalendarSetImageDirectory is called inside the enclosing body
element. At this time the onload tag of the body element is set.
You can test this if you change the body element to body
onload=alert('test body onload'); of the simple/calendar.jsp example..
Regards,
Paul

Thank you for your tipps and sorry for my late answer. I had much to do

In the meantime we got a new CSS file and the calendar popups are
working fine in IE after resetting some div...
The examples out of the myfaces repository are working on both: Firefox
and IE. There I had no problem with the js script.
I think we have to be careful using css...
But, I have now a problem with Firefox popups to display them and this
is because we use the onload tag and some own javascript init
functions for the page.
Now I checked the popcalendar.js code and the function
jscalendarInit() is only called if there is no window.onload (onload
tag) in the browser specified if no IE is used. This is why the variable
jscalendarBPageLoaded still remains with the default value false and
Firefox never executes this:
-
function jscalendarPopUpCalendar(ctl, ctl2, format){
if (jscalendarBPageLoaded){
-
Is this right that I can't use the onload tag using Firefox?

it's a known bug of the IE - you would need to go through the elements
of the form and render them invisible while displaying the
inputCalendar.
If you prepare a patch for the javaScript of inputCalendar which works
in IE and Firefox we would happily apply it!

RE: Hibernate: 1-to-many -- struggling
Werner,
Since you have data associated with your many-to-many, you can simplify this
by making an entity in the middle, transforming your many-to-many in to a
many-to-one, one-to-many from the ORMs perspective.
We can continue this discussion on the Hibernate forum, if you like. I'd be
glad to help you out.

Subject: Re: Hibernate: 1-to-many -- struggling
Well maybe the original guy did not use session.saveOrUpdate
on the parent element...
I usually deal with 1:n which usually are far less
problematic then m:n (which is the case where you usually
sink 90% of the dev time banging your head and cursing
hibernate left and right) is to have a 1:n rel, with a set
mapping and to use cascade all with a save on the root element.
That has worked best.
The crux of hibernate is, you have so many ways to solve
things for everything around 100 ways, but 90 of them fail
with either no error or cryptic error messages once you have
to apply them, while there still is a huge lack of best
practices especially in the areas many-to-many and one-to-many
I will give an example:
Implicit mapping, not working if you have additional data in
your many to many binding table, now how do you resolve that
you can resolve it via an explicit binding object
declaration, the doc is very vague on this approach,
you finally get it up and running, loading works, but
deleting utterly fails with a cascade error, no real help in
the forum, after banging your head for straight 8 hours you
finally know why this happens, you delete the objects with an
explicit delete and regenerate the binding objects, but the
binding table does not have a surrogate, you do that within
the same transaction.
What wouldnt pose a problem in straight JDBC because you
clear the m:n elements out of the many to many table before
setting them anew, causes hibernate to choke.
Solution, set the relational binding to lazy thus the objects
do not get marked as deleted before loading the parent object
and thus the setting works again.
It is cases like that, which are very commmon where all the
documentation unfortunately utterly fails and where you can
sink hours into hibernate.
Hibernate to my taste lacks a high level layer which resolves
such cases automatically, some kind of
hibernatetool.resolveManyToManyBinding(BindingList) would
have helped a lot in this case.
Before Hibernate 2 it also was the session handling which
lacked those tools, that fortunately is resolved now.

I am struggling with Hibernate 1-to-many mapping(collection).
Could someone tell me how to manage the collection of
one-to-many mapping? a
little code will be very helpful.
I have a very simple one-to-many relationship: an Item has
many Picture(s).
ENTITY -- Item
@...
public class item {
private Collection pictures;
private Integer id;
// getter/setter for id and @Id(...)
@OneToMany(cascade = {CascadeType.MERGE}, fetch = FetchType.EAGER,
mappedBy=item)
public Collection getPictures() {
return pictures;
}
public void setPictures(Collection pictures) {
this.pictures = pictures;
}
public void addPicture(Picture p) {
if (pictures == null)
pictures = new ArrayList();
pictures.add(p);
}
}
ENTITY Picture --
@
public class Picture {
private Item item;
private Integer id;
// constructor
public Picture(Item item, ) {
this.item = item;
}
// getter/setter for id and @Id(...)
@ManyToOne
@JoinColumn(name=itemId)
public Item getItem() {
return item;
}
public void setItem(Item item) {
this.item = item;
}
}
I create an Item in persistence without any pictures. Then
use a session
bean to add pictures to the item.
Session Bean --
@Stateless
public class ItemManagerBean implements ItemManager {
public void addPictureToItem(Item item, Picture p) {
item.addPicture(p);
em.merge(item);
}
}
The merge() ignores those pictures that are already in persistence.
Add picture P1: --- persistence: P1, ( great!)
Add picture P2 --- persistence: P1, P1, P2 (P1 duplicated)
Add picture P3 --- persistence: P1, P1, P2, P1, P2, P3
Obviously, the merge() ignored what are already in
persistence. All pictures
has Id. EM.merge() should be able to know P1 is already in
persistence when
adding P2.
I f I do not call merge(), nothing will be persisted.
I do this from Web GUI.
Re: commandLink with action inside Table

Hello,
I try to use a commandLink with an action inside a treeTable but it is
not working properly :-(
The following snippet of a treeTable-column is expected to:
- render a link if it 's the tableHead
- render a outputText if it's a row inside the tableBody
- render a outputText with a special style if it's selected
h:column id=columnBrowsTab1 rendered=#{foo.secondBoolean}
h:commandLink
action=#{listener.sort}
immediate=true
rendered=#{foo.obid == 'obid'}XX/h:commandLink
h:outputText value=#{foo.secondColumn}
rendered=#{foo.obid != 'obid' and !(foo.obid == listener.obid)}/
h:outputText value=#{foo.secondColumn}
rendered=#{(foo.obid == listener.obid)}
styleClass=treeNodeSelected /
/h:column
The result so far looks good, but the ACTION method of the link gets
only fired if the tableBody is empty.
Any ideas to solve this problem???

Re: Map managed bean with managed properties
Yeah you can use expressions (JSF Spec 1.1 Section 10.3.1 Page
285). I use Spring's delegating variable resolver to expose my
Spring beans through EL and then I inject references to them in this
manner. It has worked great up until the map case.
Should a bug be filed on this or is it desired behavior? I looked
through the spec for guidance here but I didn't see anything.
Thanks,

Take a look at JSF Spec 1.1 Section 5.1.3 (Get Value Semantics) and
5.1.4 (Set Value Semantics). While nothing is explicitly stated for
get value semantics (just the reference to the above, which I don't
have handy), set value semantics show that the map put operation takes
precedence over the bean setter.

Yeah you can use expressions (JSF Spec 1.1 Section 10.3.1 Page 285). I use
Spring's delegating variable resolver to expose my Spring beans through EL
and then I inject references to them in this manner. It has worked great up
until the map case.
Should a bug be filed on this or is it desired behavior? I looked through
the spec for guidance here but I didn't see anything.

What I do when I want to inject a value to another bean is get the
bean via the faces context, for example I do a
getManagedBean(detailsBean).setDetail(someObject)
(I attach the code for my getManagedBean method below)
public final static Object getManagedBean(String beanName)
{
FacesContext facesContext = FacesContext.getCurrentInstance();
Application a = facesContext.getApplication();
ValueBinding binding = a.createValueBinding(#{ + beanName +

Hi all,
I have a managed bean that implements the Map interface. The bean

able to configure the bean like this:
public class MyMap implements Map {

return myDependency;

public Dependency setMyDependency(Dependency newDependency) {
myDependency = newDependency;
// initialize contained map using myDependency

The problem I'm running into is that PropertyResolverImpl.setValue
checks to see if the bean is an instance of Map and if so, calls
put(property, value). So instead of calling MyMap.setMyDependency, it
is calling MyMap.put and passing the key = myDependency and the
value = #{someOtherBean}.
Any suggestions?

Re: commandLink with action inside Table

Basically, you need to preserve the value of rendered to the next request.
Using the t:saveState component is one way to do this.

Does the action get executed if you remove the 'rendered' attribute?

the action of the commandlink is only executed if the rendered flag
for this and his parent component is true during the decode phase.
Can you post the surrounding datatable tag also?

Hello,
I try to use a commandLink with an action inside a treeTable but it is
not working properly :-(
The following snippet of a treeTable-column is expected to:
- render a link if it 's the tableHead
- render a outputText if it's a row inside the tableBody
- render a outputText with a special style if it's selected
h:column id=columnBrowsTab1 rendered=#{foo.secondBoolean}
h:commandLink
action=#{listener.sort}
immediate=true
rendered=#{foo.obid == 'obid'}XX/h:commandLink
h:outputText value=#{foo.secondColumn}
rendered=#{foo.obid != 'obid' and !(foo.obid == listener.obid)}/
h:outputText value=#{foo.secondColumn}
rendered=#{(foo.obid == listener.obid)}
styleClass=treeNodeSelected /
/h:column
The result so far looks good, but the ACTION method of the link gets
only fired if the tableBody is empty.
Any ideas to solve this problem???
- my backingBean has session scope

PreserveDataModel behaviour (2)
Hi again,
I have investigated another interesting behaviour about using
PreserveDataModel, which makes my application crash (due to the way I'm
working with data tables). Let me explain it to you in a
straight-forward manner.
Currently, I use a session scoped bean to work with my objects (e.g.
one bean to work with customer objects, one bean to work with the
users, etc), due to the fact that I don't want to loose state between
requests (yes, I know it could have been done using
t:saveState...). So within all my session beans, I have defined
a ListDataModel variable that holds the data model that is presented to
the view every time the view is rendered (nothing strange here, I
guess).
>From my views (JSP), I simply use:
t:dataTable .. value=#{sessionScopedWhateverBean.listOfObjectsAsListDataModel}
So whenever the view is rendered, the method public DataModel
getListOfObjectsAsListDataModel() in my session scoped bean is
invoked. Obviously, the first time it will be created, and the
subsequent calls simply will return the existing object. Everything's
fine here.
The problem comes when using PreserveDataModel because, as explained in
the wiki I posted about working with PreserveDataModel, every object in
my listOfObjectsAsListDataModel is added to a new ArrayList belonging
to a new _SerializedDataModel object, which is the object being really
serialized when saving the state by the JspStateManagerImpl. And why is
it the problem? Think about the future restoring phase...
When a link is clicked inside the data table to work with a particular
object, the event created as a consequence of the clicked link has
the information about the exact row which has been clicked
(specifically in its rowIndex attribute). Following, the state is
restored, and the previously serialized data model (as a
_SerializedDataModel object) is used to set the information about the
clicked row. What does this mean? It's as simple as this: the
clicked row information is set on the restored object, so it is
really set on the _SerializedDataModel object (nothing to be with our
original ListOfObjectsAsListDataModel object).
When afterwards the broadcast calls our action method (the one
associated with the link in the data table through usually an
HtmlCommandLink tag), our session scoped bean has the original
ListOfObjectsAsListDataModel object that was used to create the
_SerializedDataModel object when saving the state. But with a
definitive difference: the rowIndex from the event was set on the
_SerializedDataModel object, not the one we have here now, i.e. our
ListOfObjectsAsListDataModel object. And due to the fact that our
ListOfObjectsAsListDataModel was used to create the
_SerializedDataModel object, now it has its internal rowIndex attribute
set to the last row plus one (obviously, as the saveState method
iterates through the ListOfObjectsAsListDataModel list of objects to
populate the _SerializedDataModel list of objects).
At the end, the result is a call to setRowIndex(last row + 1), which
obviously does not exist, so a IllegalArgumentException: row is
unavailable is thrown. On the other hand, if I don't use
preserveDataModel, everything works perfectly, as the
ListOfObjectsAsListDataModel object is the one used to save the state
(not the _SerializedDataModel).
IMHO, the solution will be as simple as updating my
ListOfObjectsAsListDataModel object with the _SerializedDataModel
object when restoring the state. But I would like to hear the MyFaces'
team experts about this possibility before going deeper into the code.
Is it feasible? Is it possible to work with the preserveDataModel
together with a DataModel inside my bean and the getRowData() method?
Is the use od preserveDataModel incompatible with using the
getRowData() method inside my bean?
Looking forward to hearing your comments :-)

Subject: Re: Hibernate: 1-to-many -- struggling
Well maybe the original guy did not use session.saveOrUpdate
on the parent element...
I usually deal with 1:n which usually are far less
problematic then m:n (which is the case where you usually
sink 90% of the dev time banging your head and cursing
hibernate left and right) is to have a 1:n rel, with a set
mapping and to use cascade all with a save on the root element.
That has worked best.
The crux of hibernate is, you have so many ways to solve
things for everything around 100 ways, but 90 of them fail
with either no error or cryptic error messages once you have
to apply them, while there still is a huge lack of best
practices especially in the areas many-to-many and one-to-many
I will give an example:
Implicit mapping, not working if you have additional data in
your many to many binding table, now how do you resolve that
you can resolve it via an explicit binding object
declaration, the doc is very vague on this approach,
you finally get it up and running, loading works, but
deleting utterly fails with a cascade error, no real help in
the forum, after banging your head for straight 8 hours you
finally know why this happens, you delete the objects with an
explicit delete and regenerate the binding objects, but the
binding table does not have a surrogate, you do that within
the same transaction.
What wouldnt pose a problem in straight JDBC because you
clear the m:n elements out of the many to many table before
setting them anew, causes hibernate to choke.
Solution, set the relational binding to lazy thus the objects
do not get marked as deleted before loading the parent object
and thus the setting works again.
It is cases like that, which are very commmon where all the
documentation unfortunately utterly fails and where you can
sink hours into hibernate.
Hibernate to my taste lacks a high level layer which resolves
such cases automatically, some kind of
hibernatetool.resolveManyToManyBinding(BindingList) would
have helped a lot in this case.
Before Hibernate 2 it also was the session handling which
lacked those tools, that fortunately is resolved now.

I am struggling with Hibernate 1-to-many mapping(collection).
Could someone tell me how to manage the collection of
one-to-many mapping? a
little code will be very helpful.
I have a very simple one-to-many relationship: an Item has
many Picture(s).
ENTITY -- Item
@...
public class item {
private Collection pictures;
private Integer id;
// getter/setter for id and @Id(...)
@OneToMany(cascade = {CascadeType.MERGE}, fetch = FetchType.EAGER,
mappedBy=item)
public Collection getPictures() {
return pictures;
}
public void setPictures(Collection pictures) {
this.pictures = pictures;
}
public void addPicture(Picture p) {
if (pictures == null)
pictures = new ArrayList();
pictures.add(p);
}
}
ENTITY Picture --
@
public class Picture {
private Item item;
private Integer id;
// constructor
public Picture(Item item, ) {
this.item = item;
}
// getter/setter for id and @Id(...)
@ManyToOne
@JoinColumn(name=itemId)
public Item getItem() {
return item;
}
public void setItem(Item item) {
this.item = item;
}
}
I create an Item in persistence without any pictures. Then
use a session
bean to add pictures to the item.
Session Bean --
@Stateless
public class ItemManagerBean implements ItemManager {
public void addPictureToItem(Item item, Picture p) {
item.addPicture(p);
em.merge(item);
}
}
The merge() ignores those pictures that are already in persistence.
Add picture P1: --- persistence: P1, ( great!)
Add picture P2 --- persistence: P1, P1, P2 (P1 duplicated)
Add picture P3 --- persistence: P1, P1, P2, P1, P2, P3
Obviously, the merge() ignored what are already in
persistence. All pictures
has Id. EM.merge() should be able to know P1 is already in

Yes, I am going to make a wiki entry this. The reason I didn't reply
immediately is that he mentioned he was using session scope for his
backing bean. I'm guessing now that both the foo bean and listener
bean both aren't in session scope.
Christian, I'm guessing that listener is not being preserved so if you
preserve listener or listener you should be all set:
t:saveState id=listener value=#{listener}/
(just perserving obid of listener should work also:
t:saveState id=obid value=#{listener.obid}/)
If foo isn't being preserved (I think you said it was in Session
scope), you'll need to save that state also. I haven't looked into using
t:saveState for more than one object though.

Creating a Custom Component with other components inside...
Hi, I'm looking at designing a simple component that would render the following: 2 ListBoxes with items in each of them. Each being plugged on a different List in the background. I'm trying to figure out how to do that right now... I have created a custom component that works but does not render my listboxes. The way I saw this was that in my component's code, in encodeBegin, I could create 2 UISelectMany components and setting their parent to my component. Now be honest... Is this a horrible way to do things :p? The reason I'm asking is because I'm trying to figure out if i can render this without having to use the responsewriter to write HTML, ie by using another component and calling its encodeBegin method so that later changes can be repercuted in my component automatically. Are there any examples of custom components that do this? I'm figuring I could use the ResponseWriter and iterate through the ListBoxes' lists etc... but I'm wondering if creaeting the components and setting their required properties is possible. Thanks a lot, Greg
RE: Creating a Custom Component with other components inside...
I remember trying to learn custom components by creating a form builder
that will create a form from XML file.
What I did was to create a Label component and a HtmlInputText component
as to the number of properties specified and add Validators
accordingly.(Only regular Expression validator though). Add these
components to my component.
I did the above in encodeBegin(). In the encodeChildren(). Loop thru my
component and call the renderers of these children.
However, what I realised was I had a check at the start like this...
If(myComponent.getChildren().size == 0)
{
//Create the needed type of Uicomponents and add to
myComponent.getChildren().add()
}
I think this check was not needed...However, it was my test
component...so left it at that
To make the long story short, yes, you can do it the way you had
mentioned. Most of the composite components that aggregates components
like this, does that I guess.\
Hope this helps.

Your structure is very Struts like, which is not really needed. extends AbstractViewController you wont need that in JSF unless you have something really important down there, which you have to reuse also you wont need to think in actions and forms (beans) like you do in struts, everything is a backing bean.

Ah I just googled, the AbstractViewController is Shale, that explains a lot ;-)...

Does the AbstractViewController do something special in Shale or is it simply a class to ease the transition from Struts and enforce MVC?

If you are using extension mapping *.jsf the following redirect should work. % response.sendRedirect(response.encodeRedirectURL(/pages/launch.jsf)); % Thomas On 9/16/05, Robert Taylor [EMAIL PROTECTED] wrote: Greetings, I'm a current Struts user interested in learning and usingMyFaces and JSF.My dev. env. consists of Tomcat 5.5.9, MyFaces 1.0.9, JDK 1.4.2, Win2K.I've configured MyFaces to use Tiles for view-handler.

Re: setting headers on the response in JSF
If you don't want to implment a PhaseListener or a javax.servlet.Filter for setting response headers, think about using MyFaces Tiles-Support. You'd just need to define a scriptlet in one (maybe a few) JSP templates.

Re: Help your brothers and sisters- Suggestions for improving this JSF example
I believe it's needed in order to get the various methods called within the JSF life-cycle... such as the use of prerender. >From the Shale http://struts.apache.org/shale/features.html#view Each backing bean that implements ViewController will support a boolean property postback, which will be set to true if this view is the one that is processing a form submit previously rendered by the same page, or false if this view was newly navigated to. The property will be set before any of the lifecycle methods described below are called, so that application logic may perform conditional tasks based on this state. As part of the standard JavaServer Faces managed beans processing, any managed-property elements in the configuration file, that are nested inside the managed-bean element for this backing bean, will also be processed when a new bean instance is created. You can use either literal values or value binding expressions to customize properties on your backing bean class. Fans of Dependency Injection will see that the managed beans facility provides support for such a framework, using Setter Injection as the mechanism for injecting dependencies. In addition, the following lifecycle events are called, by the framework, at certain points in the JavaServer Faces request processing lifecycle: init() - Called immediately after the view that this backing bean is associated with is created. (Technically, it happens when ViewManager.createView() is called.) For a postback, this happens during the Restore View phase of the request processing lifecycle, once it ha been determined which view should be restored. If your application navigates from one page to another, the init() method of the second page will be called as part of the NavigationHandler.handleNavigation() processing. Use this method to acquire resources that you will need, no matter whether this is a postback request, a rendering request, or both. preprocess() - Called after the Restore View phase has been completed, but before Apply Request Values phase starts, only for the view that will be processing the postback. Use this method to acquire resources (such as database connections) that you will need to process the postback. prerender() - Called immediately before the Render Response phase that actually causes the view to be rendered. This method will only be called for the view that is actually rendered (the current view if you are redisplaying, or the new view if you perform navigation). Use this method to acquire resources (such as database connections, or performing queries) that you will need if this view is the one to be rendered. NOTE - when portlet support is integrated, all of the portlets on the current page will receive this event. destroy() - If init() was ever called for a ViewController, then it is guaranteed that destroy() will be called as well. Use this method to release any resources acquired during an earlier event handler.

Your structure is very Struts like, which is not really needed.extends AbstractViewController you wont need that in JSF unless you have something really important down there, which you have to reuse also you wont need to think in actions and forms (beans) like you do in struts, everything is a backing bean. A divided MVC approach is very viable, but you also can use a simplified combined model controller approach. Sun uses this strategy in their studio creator to enable a Visual basic like handling of the backend code.

Navigation Panel Question
Hello all, I just noticed a problem with my navigation panel. I have a top level "home" link that takes the user to the index page. If I use the component to browse to a link in a lower directory, then click the home link, the page renders without any style information. It's as if the style sheet fails to load. If I click it again, everything reverts to normal and life is good again. Has anyone else encountered this? Thanks!
Re: Navigation Panel Question
Could be to do with your browser trying to load your link'ed css resource from a location that is relative to the page's location in your web-app. That's why it works at the top level and not at any lower level. As a test, trying including a base tag in your htmlhead section in the lower-level page. Although it's probably not what you want to do in the long run, you could try pasting in something like this: base href=%=request.getScheme() + :// + request.getLocalName() + : + request.getLocalPort() + request.getContextPath() + /test.htm % If it starts working, at least you know the problem :) -Jess.

t:columns data conversion
Previously I used h:column with dataTable, data conversionwas done by JSF between String/Integer, String/BigDecimal. When I changed it to use t:columns for variable number of columns, I got error.
Cannot set value for _expression_ '#{backingBean.columnValue}' to a new value of type java.lang.String
In the backing bean:
public Object getColumnValue();
public void setColumnValue(Object value);
The value passed into setColumnValue() is always String.
t:dataTable does not keep track of data type for each column and then convert data automatically. So I need to make data conversion in setColumnValue(Object value) for all columns.
Am I correct? Thanks! Dave__Do You Yahoo!?Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com
