Please try this :

In process action :

actionRequest.setAttribute("paramName", paramValue);

In render method :

String value= renderRequest.getAttribute("paramName");
renderRequest.setAttribute("paramName", value);

In JSP:

String value= (String) request.getAttribute("paramName");

Thanks.

Hi,
I want to sent a list to populate the right list of the input-move-boxes.
Really, i didn't understand so much wich param i have to put.
view.jsp:

<<% 

           List leftBox = new ArrayList(), rightBox = new ArrayList(); 
           leftBox.add(new KeyValuePair("1", "Player1"));
           leftBox.add(new KeyValuePair("2", "Player2"));
           leftBox.add(new KeyValuePair("3", "Player3"));
           leftBox.add(new KeyValuePair("4", "Player4"));
           leftBox.add(new KeyValuePair("5", "Player5"));
           

%>
<form action="<%= actionURL1 %>" method="post" name="<portlet:namespace />fm">  
 
	<aui:select name="selectChannel" label="Select a channel">
	    		<aui:option value="channel1"> Channel1</aui:option>
	            <aui:option value="channel2"> Channel2</aui:option>
	            <aui:option value="channel3"> Channel3</aui:option>
	            <aui:option value="channel4"> Channel4</aui:option>
	            <aui:option value="channel5"> Channel5</aui:option>
	            
	</aui:select>	
	 
	 
	 <liferay-ui:input-move-boxes rightlist="<%= request.getAttribute(\" playerslist\")%>"
	 rightTitle="Selected Players" 
	 leftBoxName="allFieldsList" 
	 leftList="&lt;%=leftBox%&gt;" 
	 rightBoxName="displayFieldsList" 
	 leftTitle="available Players" 
	 leftReorder="false" 
	 rightReorder="true" 
	 cssClass="custom-move-boxes" /&gt; 
	     
	  <input name="<portlet:namespace />hiddenLeftFields" id="<portlet:namespace />hiddenLeftFields" type="hidden">     
	 <input name="<portlet:namespace />hiddenRightFields" id="<portlet:namespace />hiddenRightFields" type="hidden">   
	 <center><input onclick="<portlet:namespace />submitForm();" type="button" value="Validate" cssClass=".submitButton"> 
	 
	</center> 	
	 
  </liferay-ui:input-move-boxes></form>

what i want is when i select a channel from the list, the right list of the input-move-boxes got the appropriate data.

Hi Jam,

You have to create list of key/value pair in action method to pass in jsp.

In action method,

List<keyvaluepair> displayFields = makeKeyValuePar(leftValuesArray);
		
actionRequest.setAttribute("displayFields", displayFields);
	
//you can use below method to generate list of key/value pair which we need to pass in rightBox
private static List<keyvaluepair> makeKeyValuePar(String[] values) {
		List<keyvaluepair> keyValuePairList = new ArrayList<keyvaluepair>();
		for (String val : values) {
			val = ListingUtils.columnNameStaticMapping(val);
			KeyValuePair obj = new KeyValuePair();
			obj.setKey(val);
			obj.setValue(val);
			keyValuePairList.add(obj);
		}
		return keyValuePairList;
	}</keyvaluepair></keyvaluepair></keyvaluepair></keyvaluepair>

In render method,

renderRequest.setAttribute("displayFields", renderRequest.getAttribute("displayFields"));

Thanks.
