Error when reloading scrollableDataTable in browser error wi

[jingjingfu]

Here is the environment: Richfaces 3.1.2, portlet-3.1.0-SNAPSHOT.jar (bridge), liferay portal, JSF 1.2, facelets, Tomcat 6 and firefox. We put the scrollableDataTable within facelet . scrollableDataTable comes up fine in liferay portal, and works as expected. But if we hit the "reload" button in browser, it crashes with this classic JSF error: java.lang.IllegalStateException: duplicate Id for a component.

Note this error only happens for page with data bing, and only happens when reload browser, and only happens if it is portal. I can't duplicate it in a servlet.

So is it a known issue in the portlet bridge, or there is already workaround? Appreciate any help.

BTW, I tried the "portlet-3.2.0.jar", but any page comes up blank. Anyone got "portlet-3.2.0.jar" working?

One workaround I just discovered is to set the backing bean scope to "request" instead of "session". Thanks!

Hello!

We had the same problem.

But changing the scope to "request"degraded the scrolling performance while using a large table (160000 rows).

Using ui:debug, see for example http://www.roseindia.net/jsf/debug.shtml, I found out that the component id of the outputText was doubled. So I added an id

id="o1"

for that components:

<rich:column id="nidentifier" sortable="false" width="80px">
 <f:facet name="header">
 <h:outputText styleClass="headerText" value="nidentifier" />
 </f:facet>
 <h:outputText id="o1" value="#{category.nidentifier}" />
</rich:column>

Now it seems to work.

Greetings
