scrollableDataTable : issues with selection attribute

[mchepuri]

Hi,
I am running in to exceptions when i use selection attribute with scrollableDataTable tag.
Exception :

org.apache.jasper.el.JspELException: /SdPlaylistStatus.jsp(308,8) '#{sdPlaylistStatusManaged.selection2}' java.lang.IllegalArgumentException: argument type mismatch
org.apache.jasper.el.JspValueExpression.setValue(JspValueExpression.java:94)
org.richfaces.renderkit.html.SelectionRendererContributor.decode(SelectionRendererContributor.java:123)
org.richfaces.renderkit.CompositeRenderer$1.execute(CompositeRenderer.java:77)

Note: I used both
org.richfaces.model.selection.SimpleSelection;
org.richfaces.model.selection.Selection; in my backing bean.


Here is my jsp code.

<rich:scrollableDataTable id="sampleData1" rowKeyVar="rkv"
 value="#{sdPlaylistStatusManaged.logMsgList}" var="row1"
 rows="3" selection="#{sdPlaylistStatusManaged.selection1}">
 <a4j:support event="onRowClick" action="#{sdPlaylistStatusManaged.takeSelection}"/>

and backing bean code.

import org.richfaces.model.selection.SimpleSelection;
import org.richfaces.model.selection.Selection;

public SimpleSelection getSelection1() {
 return selection1;
 }
 public void setSelection1(SimpleSelection selection1) {
 this.selection1 = selection1;
 }

public String takeSelection() {
 System.out.println("takeSelection");
 Iterator iterator =getSelection1().getKeys();
 while (iterator.hasNext()){
 SimpleRowKey key = (SimpleRowKey)iterator.next();
 System.out.println(key.intValue());
 }
 return null;
 }

I got above exception when i use Selection as component class for my selection1.

ie some thing like this in my backing bean.

private Selection selection1;

I got below exception when i use SimpleSelection as componenet class for selecttion1.

ie some thing like this in my backing bean.

private SimpleSelection selection1 = new SimpleSelection();

I got below exception when use SimpleSelection as componenet class for selecttion1.

i suspect that this error has the same source as the one im experience... outlined in the thread below this.

[nathandennis]

have you figured this out yet?? its still nagging me aswell.

[nathandennis]

this smells of bug... it works with older versions. perhaps we should file a ticket in jira

[nathandennis]

nope that isnt it either... bad test...
could someone that knows please comment on this..

[pavel.myshkin]

You have a complete solution to it here http://blog.javarnd.com/?p=91.

Hello,

Looks like a classloader issues. I've just checked richfaces-demo, works fine with the latest 3.3.0-snapshot. So can you please provide some more information:

1. RF version
2. Seam version (if any)
3. Application server version
4. Project layout (EAR/WAR)?

[nathandennis]

for some reason it didnt send a email on reply ... thanks for the responses and patience.

richfaces snap 3.3.0 12/26/08
seam 2.1.0.sp1
jboss.4.2.2.ga
EAR

i have richfaces api impl & ui in ear/lib and ear/war/web-inf/lib

[nathandennis]

i looked at the working example. it is almost the same as the demo example in the trunk.

i suspect after all this is sorted out we will find that it is an issue integrating richfaces with seam. according to the seam doc,, UIComponents must be stored in a bean of EVENT scope. that bean can then be injected into the conversation scope. this is the approach i took with no success.

Looks like that's the thing causing problems. Class with the same name is being loaded from two different locations leading to CCE. Does it work if you leave api .jar in ear/lib and impl, ui .jar files in war/WEB-INF/lib? Please try.

Hi,
I have the same problem like mchepuri.
I tried it with:
- AS 4.2.2.GA
- Seam: 2.1.0.GA / 2.1.1.GA
- RichFaces: 3.2.0.SR1 / 3.2.2.GA / 3.2.2.SR1 / SNAPSHOT(20090104.050652-112)

but no success.

Can anyone help me to get the row selection in scrollableDataTable?
My Code is like that in RichFaces FAQ (http://www.jboss.org/file-access/default/members/jbossrichfaces/freezone/docs/devguide/en/faq/faq.html) and I got the same errors like mchepuri.

Thanks.

tuncty, have you read previous comment, especially:
