--------------------------------------
Fix Version: Nightly
Resolution: Won't Fix
Assign To: Mathias Broekelmann
Will be fixed in RI, not with us.
This bug has a similar outcome, but not the same reasons as MYFACES-853 and MYFACES-1009, so please make sure you indicate if you are using the RI if you post information about this fix on the list.

> Environment: Apache Tomcat 5.5.12 or OC4j 10.1.3 DP4, Win Xp, Sun RI 1.1.01 , JDK 1.5

> Hi,
> I'm trying using Tomahawk t:dataTable and it seems to me that its behaviour is very different from the standard JSF h:dataTable.
> Consider a column which contains a command button and a table with two rows. When the user clicks on the button of the first row, two action events are generated!
> For example, look at this very simple code:
> <f:view>
> <h:form>
> <h:dataTable value="#{testBean.persons}" var="item" binding="#{testBean.uiData}">
> <h:column>
> <h:commandButton value="Test" action="#{testBean.test}"></h:commandButton>
> </h:column>
> <h:column>
> <h:outputText value="#{item.name}"></h:outputText>
> </h:column>
> <h:column>
> <h:outputText value="#{item.surname}"></h:outputText>
> </h:column>
> </h:dataTable>
> <t:dataTable value="#{testBean.persons}" var="item" binding="#{testBean.htmlDataTable}" preserveDataModel="false">
> <t:column>
> <h:commandButton value="Test" action="#{testBean.test2}"></h:commandButton>
> </t:column>
> <t:column>
> <h:outputText value="#{item.name}"></h:outputText>
> </t:column>
> <t:column>
> <h:outputText value="#{item.surname}"></h:outputText>
> </t:column>
> </t:dataTable>
> </h:form>
> </f:view>
> When the user clicks the "Test" button of the h:dataTable, the "testBean.test" method is executed just one time.
> But when the user clicks the "Test" button of the t:dataTable the "testBean.test2" method is executed twice ( or three times if the table has 3 rows, and so on...).
> I suppose that the problem is that the elements of t:dataTable which belongs to differnt rows have the same ID, and during the processDecode phase the same event is broadcasted more than one time.
> In fact, this is the html code which is generated by Tomahawk extended datatable:
> <table>
> <tbody id="_id0:_id8:tbody_element">
> <tr>
> <td><input type="submit" name="_id0:_id8:_id10" value="Test" /></td>
> <td>John</td>
> <td>Smith</td>
> </tr>
> <tr><td><input type="submit" name="_id0:_id8:_id10" value="Test" /></td>
> <td>Mark</td>
> <td>Greene</td>
> </tr></tbody>
> </table>
> and this is the html code which is generated by RI h:dataTable:
> <table>
> <tbody>
> <tr>
> <td><input type="submit" name="_id0:_id1:0:_id3" value="Test" /></td>
> <td>John</td>
> <td>Smith</td>
> </tr>
> <tr>
> <td><input type="submit" name="_id0:_id1:1:_id3" value="Test" /></td>
> <td>Mark</td>
> <td>Greene</td>
> </tr>
> </tbody>
> </table>
