Secondly my last question, is keepAlive = session?

keepAlive works like conversation scope from Seam or viewScope from JSF 2.

and why it throws exception when i use keepAlive?

neither session scoped objects nor kept alive ones should be used to store component binding.

then how to resolve this issue?

[waq]

The link provided by Nick tells that it can not be done using keepAlive. But i need to find some work around or some alternative for this bug.

       Hi, Waqas Arshad, I think your search button shuld be a non-ajax button, then after clicked the search button, the whole page will be refreshed, and in server side the <t:saveState/> knows what to be saved.

even this doesn't solved the problem......

  What problem, exception?

No exception.

I changed search button frm ajax to jsf and place the t:saveState and put my dictionary list bean in the saveState but still action is not called.

[yyq2009]

     Show me some brief page code.

[waq]

<h:form id="search_form">

<a4j:region selfRendered="true" id="word_region">

<h:inputText id="search_fld" value="#{dictionary.word}" size="50" />

<h:commandButton value="Search"

action="#{dictionary.searchWord}"

reRender="detail_table, table_div" id="searchBtn" />

<h:selectOneRadio id="myRadio" value="#{dictionary.search_filter}"

styleClass="text" style="font-style: oblique;">

<f:selectItem itemValue="exact" itemLabel="Exactly" />

<f:selectItem itemValue="start_with" itemLabel="Start with" />

<f:selectItem itemValue="contain" itemLabel="Contain" />

</h:selectOneRadio>

</a4j:region>

<a4j:outputPanel id="table_div" layout="none">

<h:dataTable id="detail_table" var="dic" border="0"

rowClasses="even_rows, odd_rows" cellpadding="2" cellspacing="1"

rows="5" value="#{dictionary.dictionayList}"

binding="#{dictionary.dataTable}">

......

<h:column headerClass="datatable_width_detail">

<f:facet name="header">

<h:outputText value="" />

</f:facet>

<a4j:commandLink action="#{dictionary.showDetails}"

value="Detail" oncomplete="Richfaces.showModalPanel('panel')"

reRender="panel" />

</h:column>

</h:dataTable>

<br />

<rich:datascroller align="center" for="detail_table" maxPages="20"

renderIfSinglePage="false">

</rich:datascroller>

</a4j:outputPanel>

<t:saveState value="#{dictionary.dictionayList}" />

<rich:modalPanel id="panel" width="600" height="300"

autosized="true">

.....

</rich:modalPanel>

[waq]

sorry button does not contain re-render attribute. its

<h:commandButton value="Search"

action="#{dictionary.searchWord}"

id="searchBtn" />

[yyq2009]

      Remove the region tag or be sure that the <t:saveState/> is in region zone.

[waq]

its still not working, code is:

<h:form id="search_form">

<h:inputText id="search_fld" value="#{dictionary.word}" size="50" />

<h:commandButton value="Search" action="#{dictionary.searchWord}" id="searchBtn" />

<h:selectOneRadio id="myRadio" value="#{dictionary.search_filter}" styleClass="text" style="font-style: oblique;">

<f:selectItem itemValue="exact" itemLabel="Exactly" />

<f:selectItem itemValue="start_with" itemLabel="Start with" />

<f:selectItem itemValue="contain" itemLabel="Contain" />

</h:selectOneRadio>

<a4j:outputPanel id="table_div" layout="none">

<h:dataTable id="detail_table" var="dic" border="0"

rowClasses="even_rows, odd_rows" cellpadding="2" cellspacing="1"

rows="5" value="#{dictionary.dictionayList}"

binding="#{dictionary.dataTable}">

......

<h:column headerClass="datatable_width_detail">

<f:facet name="header">

<h:outputText value="" />

</f:facet>

<a4j:commandLink action="#{dictionary.showDetails}"

value="Detail" oncomplete="Richfaces.showModalPanel('panel')"

reRender="panel" />

</h:column>

</h:dataTable>

<br />

<rich:datascroller align="center" for="detail_table" maxPages="20"

renderIfSinglePage="false">

</rich:datascroller>

</a4j:outputPanel>

<t:saveState value="#{dictionary.dictionayList}" />

<rich:modalPanel id="panel" width="600" height="300"

autosized="true">

.....

</rich:modalPanel>

This problem is really sqeezing.

Isn't any way to do it the way i was doing previuosly? I mean instead of rendering entire page, i just need to do partial submitting using ajax.

You can split your bean into two beans - the first holds properties and is kept alive, the second contains reference to the bound component.

Another options is to redesign your code, so that binding isn't necessary anymore.

[yyq2009]

Hi, Waqas Arshad, I'm sorry that I didn't noticed you binding the datatable to backing bean. Excep binding the datatable, everything works for me.

[waq]

but without binding datatable how would you pick the selected row data?

[ilya_shaikovsky]

by using parameters like there
