Description
from: [jsr-314-open] Ajax inside a DataTable
Cagatay Civici
I've faced with an issue in our app I'd like to share when trying to update the datatable itself from a command element located inside a column. Case is to select a row, execute logic and update the datatable. Basic code:
<h:dataTable id="cars" var="car" value="#
{tableBean.carsSmall}">
<h:column>
<f:facet name="header">
Model
</f:facet>
<h:outputText value="#
" />
</h:column>
<h:column>
<f:facet name="header">
Action
</f:facet>
<h:commandButton value="Some Action" actionListener="#
">
<f:ajax render="cars" />
</h:commandButton>
</h:column>
</h:dataTable>
As datatable has a rowIndex >= 0 during rendering of commandButton f:ajax defines the component id to render as cars:
{rowIndex} where I should expect "cars" only. This is due to UIData.getClientId implementation as UIData
adds rowIndex for unique row ids. This causes an issue with a nested f:ajax case.

We should never include the row-index in the client-id of the table
itself. For this, we need to revise the client-id generation
algorithm.
Without actually having tried it, I think that it is easy to do so, as
we have a UIComponentBase.getContainerClientId() to create the
client-id of the children - when this method is called, we append the
row-index, if getClientId() itself is called, we donĀ“t.

MYFACES-2788 setRowIndex still uses getClientId instead of getContainerClientId for saving and restoring row states
