ValueChangeListeners and Validators does not fire under dataTable
Hi all,
I'm very new to JSF and I'm having a really hard time with it performing a simple task as trying to get only the rows that were changed under dataTable using inputText:
this is the part of the page that displays the data:
<h:form binding="#{b_application_params.outerForm}" id="outerForm">
<h:messages layout="table" styleClass="error"
showDetail="true"/>
<h2>Application parameters</h2>
<table width="100%" cellpadding="3" cellspacing="3" border="0" class="outerBg">
<tr>
<td width="10%">choose:</td>
<td>
<h:selectOneMenu immediate="true" id="catagoryList"
tabindex="1" required="true"
binding="#{b_application_params.catagoryList}">
<f:selectItems value="#{b_application_params.siCatagoryList}"
binding="#{b_application_params.selectItems1}"
id="selectItems1"/>
</h:selectOneMenu>
</td>
</tr>
</table>
<p align="left">
<h:commandButton value="show"
binding="#{b_application_params.btnShowParams}"
id="btnShowParams"
styleClass="form_btn"
action="#{b_application_params.displayApplicationParams}"/>
</h:form>
<h:form binding="#{b_application_params.innerForm}" id="innerForm">
<h:messages layout="table" styleClass="error"
showDetail="true"/>
<h:dataTable var="appParam"
binding="#{b_application_params.paramTable}"
id="paramTable"
value="#{b_application_params.parameters}"
headerClass="table_header"
rowClasses="tbldrk, tbllght"
style="width: 100%;"
cellpadding="1"
cellspacing="1">
<h:column>
<f:facet name="header">
<h:outputText style="width: 10%;"/>
</f:facet>
<h:selectBooleanCheckbox/>
</h:column>
<h:column>
<f:facet name="header">
<h:outputText value="param name" style="width: 40%;"/>
</f:facet>
<h:outputText id="appDescription" value="#{appParam.description}"/>
</h:column>
<h:column>
<f:facet name="header">
<h:outputText value="param value" style="width: 50%;"/>
</f:facet>
<h:inputText value="#{appParam.value}" dir="ltr"
required="true" id="appValue"
valueChangeListener="#{b_application_params.appParam_valueChangeListener}">
</h:inputText>
</h:column>
</h:dataTable>
<p align="left">
<h:commandButton value="submit"
binding="#{b_application_params.saveDataBtn}"
id="saveDataBtn"
styleClass="form_btn" type="submit"/>
</h:form>
Selecting a value fromcatagoryList and clicking on theshow button will display a tableData with 3 columns;
1. empty check boxes (I only add it cause i tried to find a work around solution).
2. param name - output text.
3. param value - input text - that can be modified.
After editing the required data the user then clicking thesubmit button to save the data. As you can see theparam value has a binding to a valueChangeListener method
publicvoid appParam_valueChangeListener(ValueChangeEvent valueChangeEvent)throws AbortProcessingException{
System.out.println("appParam_valueChangeListener");
}
that never been fired when I'm submitting the form.
I searched the forums and tried to use all kind o other solutions but I just can't figure it out.( The managed bean is defined in the request scope. )
