Is partial submit possible for trinidad components

Question

Hi,
I am designing a mobile browser application. I have to use partial page refresh. Requirement is that Clicking on an image link on the page should display data in the table corresponding to the selected image. I am able to achieve that using ADF components. But not able to achieve the same using trinidad components. As far as i know mobile browser doesnt support ADF components and supports only trinidad components. Is there any trinidad component similar to Image Link in ADF which can be submitted partially?
Thanks

Hi,
I was actually using <af:commandLink>. After changing it to <tr:commandLink>, actionListener (managed bean method) is getting called now. Following is the code i have written in managed bean method
public void setEmployeeId(ActionEvent actionEvent) {
System.out.println("Inside seemp");
// Add event code here...
employeeId = actionEvent.getComponent().getId();
System.out.println(actionEvent.getComponent().getValueExpression(employeeId));
DCBindingContainer m_bindingContainerObj = (DCBindingContainer)ADFContext.getCurrent().getExpressionEvaluator().evaluate("#{bindings}");
DCDataControl dataControlObj = m_bindingContainerObj.findDataControl("TweetAppModuleDataControl");
TweetAppModuleImpl am = (TweetAppModuleImpl) dataControlObj.getDataProvider();
Collection<HashMap> employee = am.setEmployee(employeeId);
empModel = new SortableModel(employee);
//AdfFacesContext.getCurrentInstance().addPartialTarget(getSetEmployeeTable());
AdfFacesContext.getCurrentInstance().addPartialTarget(getMobileEmpTable());
//call the app module impl funtion which will set the where clause value
This method is avaialble inAppModule
public Collection<HashMap> setEmployee(String employeeId) {
ViewObjectImpl tweetVO;
tweetVO = getTweetsView1();
System.out.println("TweetViewImpl = " + tweetVO);
tweetVO.setWhereClause("employee = :emp");
tweetVO.defineNamedWhereClauseParam("emp", null, null);
tweetVO.setNamedWhereClauseParam("emp", "Duncan Angove");
System.out.println(tweetVO.getQuery());
tweetVO.executeQuery();
Collection<HashMap> employee = new ArrayList<HashMap>();
while (tweetVO.hasNext()) {
HashMap emp = new HashMap();
Row searchRow = tweetVO.getRowSetIterator().next();
emp.put("Eventtype", searchRow.getAttribute(2).toString());
System.out.println(searchRow.getAttribute(2).toString());
employee.add(emp);
return employee;
JSF Code
<tr:commandLink id="cl1" partialSubmit="true"
actionListener="#{Tweets.setEmployeeId}">
<tr:image source="/john.gif" id="i1"/>
</tr:commandLink>
<tr:table value="#{Tweets.empModel}" var="row"
rows="#{Tweets.empModel.rowCount}"
emptyText="#{bindings.TweetsView1.viewable ? 'No data to display.' : 'Access Denied.'}"
id="t1" binding="#{Tweets.mobileEmpTable}">
<tr:column sortProperty="Eventtype" sortable="false"
headerText="#{bindings.TweetsView1.hints.Eventtype.label}"
id="c1">
<tr:inputText value="#{row.bindings.Eventtype.inputValue}"
simple="true"
required="#{bindings.TweetsView1.hints.Eventtype.mandatory}"
columns="#{bindings.TweetsView1.hints.Eventtype.displayWidth}"
maximumLength="#{bindings.TweetsView1.hints.Eventtype.precision}"
id="it1">
<f:validator binding="#{row.bindings.Eventtype.validator}"/>
</tr:inputText>
</tr:column>
</tr:table>
But i am getting below mentioned error . Also on the browser it is showing Error 403
<PanelPartialRootRenderer><encodeAll> Error during partial-page rendering

Cant we use AppModule for mobile supported app? Or there are some extra setting required? FYI, following code for bean and app module is working fiine with normal adf compoennts. So i have tested that code for with simple jsf page. What i dont know if the same code will be supported by trinidad components or not
Thanks
