rich:dataTable synchronization problem

[g4j]

Hi,

I open firefox window with the rich:dataTable information on screen and minimize it. This is SCREEN1.

Now, I open ANOTHER whatever screen, called by SCREEN2, and create new row data (new record) that appears on rich:datatable's first position. The rich:displayTable displays new record normally.

Returning at SCREEN1, I click on row data that would appear after  when "managedbean" recover the wrong data (data from other record).

Hi Gerson,

I guess bean scope is "session".

So here are some possible ways to solve the problem:

- Make list conversation-scoped (requires Seam)

- Use Seam's entity converter as rowKeyConverter for data table

- Implement custom data model for the table that will use persistent identifiers as row keys (take a look at RichFaces livedemo demos)

- Put list into conversation scope or use a4j:keepAlive

Hi Nick!

My scope isn't session.

I use richfaces + spring + hibernate. My beans are managed by Spring via org.springframework.web.jsf.DelegatingVariableResolver.

The bean is defined as:

<bean id="countryMBean" class="com.tti.hd3web.register.faces.CountryManagedBean"></bean>

The .xhml and .java bean were attached.

Thanks in advance!

I saw the example. My implementation looks like livedemo, but, live demo doesn't use database and the data are randomized. When open the other window, the data are not the same.

Somebody tested the livedemo example with database and opening more than one window? I would like to know.

<bean id="countryMBean"></bean>

This means that bean is singleton (or application-scoped). Are you completely sure about the scope chosen?

You can try this example implemented using Seam entity converter: http://livedemo.exadel.com/richfaces-demo/richfaces/dataTable.jsf?tab=modifiableDataModel&cid=15287491

[g4j]

oh damn! It's true. The default scope of spring bean is singleton. I going to change and test with scope="request".

Hi Nick,

I changed scope to "request" and the related problem is persistent.

I don't see how this sample can help me. Anybody have a trick, or example?

My functionality is identical to this sample:

http://livedemo.exadel.com/richfaces-demo/richfaces/dataTable.jsf?tab=editDataTable&cid=15389267

but synchronization problem is recurrent.

[nbelaevski]

The example has the following attribute: rowKeyConverter="org.jboss.seam.ui.EntityConverter". This attaches Seam entity converter that involves one of Seam's extended scopes to preserve persistent IDs for used DB entities.

[g4j]

i tried that. Only adding the attribute don't solves. When adding rowKeyConverter attribute, i've got the exception below. Need i implement something more beyond the attribute?

My datatable:

<rich:dataTable rowKeyConverter="org.jboss.seam.ui.EntityConverter" value="#{countryMBean.list}" styleClass="dataTable" var="country" rows="13" id="countryDataTableList" reRender="dataScrollerList">

value="#{countryMBean.list}" gets the data from getList method:

public List<Country> getList() { ... }
