update rowkey?

[nimo22]

I have a contextMenu and a rich:extendedDatatable..all works.

I have a menuItem:

<rich:menuItem value="Change" ajaxSingle="true" action="#{myBean.change(row)}" reRender="showRows"/>

<rich:extendedDataTable id="showRows" ...>
</rich:extendedDataTable>

How can I reRender only the row, which was changed instead of all rows (the whole datatable) ?? Is it possible?

Yes concrete cells reRendering could be implemented for our data iteration components. Read about ajaxKeys attribute for data components. Also please check a4j:repeat richfaces-demo page.

I have a one questions about

ajaxKeys="#{listBean.list}"

listBean.list must be a Set containing only Strings (am I right?).
What Strings should I take? Strings from my Objects or ID's ?

I have no ID for my rows, only for my columns:

<rich:column id="rowID">
</rich:column>

It should be filled with rowKeys. Just simple Integers by default.

Please visit the link in my signature and checkout the sources for richfaces-demo in order to check how it works.
