problem with extended data table and client-side input valid

[koddy]

Hi,
i have an extended data table and an input field on one page. i use a jsf validator to check the user input on the client side. the validator works correctly but after the validation the extended data table is not rendered and i get the error message

_listeners' is null or not an object

.
does anyone know how to solve this problem?

provide at least code samples. environment info also will be helpfull.

<rich:extendedDataTable value="#{clients}" var="client" id="table"
selectionMode="single" selection="#{backingBean.selection}" sortMode="single" groupingColumn="group" tableState="#backingBean.state}">

 <rich:column id="group" label="Group" sortable="true" sortBy="#client.clientGroup}" filterBy="#{client.clientGroup}" filterEvent="onkeyup">

........

</rich:extendedDataTable>

<h:inputText id="new" value="#{bean.name}" required="true">
 <f:validateLength minimum="1"/>
</h:inputText>

<rich:message for="new">
</rich:message>

this is my code. i use spring webflow 2.0.5.
the validator works correctly. if the input field is empty the validator generates an error message. all gui components are ok except the data table.

may be it is helpful:
if i use the data table the error does not occur (only when i use the extended data table).
