liferay-ui:search-container pagination does not work

[Lucas Terra, modificado 8 Anos atrás.]

Hi guys,

I developed a liferay-ui:search-container, but pagination does not work, the page always lists all records, and on page appears that this listing only 20.

		<liferay-ui:search-container delta="20" emptyresultsmessage="<liferay-ui:message key=&quot;com.test.portlet.searchClient.noResults&quot;/>">		
			<liferay-ui:search-container-results results="<%= (List<User>) renderRequest.getAttribute(&quot;listUsers&quot;) %>" total="<%= (Integer)renderRequest.getAttribute(&quot;countUsers&quot;) %>" /> 
			
				<liferay-ui:search-container-row classname="com.liferay.portal.model.User" modelvar="user" escapedmodel="<%= true %>">
					
					<liferay-ui:search-container-column-text name="Primeiro Nome" value="<%= user.getFirstName() %>" />	
					<liferay-ui:search-container-column-text name="Último Nome" value="<%=user.getLastName() %>" />
					<liferay-ui:search-container-column-text name="Nome de Exibição" value="<%=user.getScreenName() %>" />
					<liferay-ui:search-container-column-text name="Cargo" value="<%=user.getJobTitle() %>" />
					<liferay-ui:search-container-column-jsp align="right" path="/html/action.jsp" />
					
				</liferay-ui:search-container-row>			
			<liferay-ui:search-iterator paginate="<%= true %>" />
		</liferay-ui:search-container>

I've tried removing

paginate="<%= true %>"

, but not resolved.

someone has gone through this?

Thank's

Hi,
Try to replace results='<%= (List<User>) renderRequest.getAttribute("listUsers") %>' with
results='<%=ListUtil.subList((List<User>) renderRequest.getAttribute("listUsers"), searchContainer.getStart(), searchContainer.getEnd()) %>'
in your liferay-ui:search-container tag

Thank you!! It worked in the first list . But when I click next , it happens a submit in view and consequently the list is empty.
This should happen as I make my list dynamically only when I click on my button get followed and a text field with the information.

Hi,
The list is empty because you get the list from renderRequest and it might be empty when the view was rendered (not sure until see complete code) . Please have a look on Liferay Pagination at this link. Quite well explained by the Author and even got example portlets.

Hi Arun I managed to solve. When I clicked next he made a new request and lost my view search parameters in renderRequest, to solve I put my parameters in the portlet session scope , not to lose in this way , he managed to hold the search again by clicking next .

example:
in processAction:

PortletSession session = actionRequest.getPortletSession();
session.setAttribute("filter","attribute-value", PortletSession.PORTLET_SCOPE);

in render:

String filter = (String) renderRequest.getPortletSession().getAttribute("filter");

Thank you so much!

As Arun said you need to pas two parameter:
1 - List of Model which you want to show on current page. This list should not be all objects. For eg. if you are on page 1, list should have record 1 to 10; if you are on page 2, list should have record 11 to 20 and so on.
2 - Total record - It used to generate pagination. For eg. if you have 25 records in DB and delta is 10, there will 3 page in pagination.

searchContainer.getStart() gives start position of records on that page
searchContainer.getEnd() gives end position of records on that page

hi

create one iteratorurl which points to same display page only
and pass one attribute containing that url in liferay ui search container tag

like <liferay-ui:search-container iteratorURL="<%=iteratorURL%>" delta="2"
emptyResultsMessage="Sorry. There are no items to display.">


total="<%= cpaneldetails.size() %>"
results="<%= ListUtil.subList(cpaneldetails,searchContainer.getStart(),searchContainer.getEnd()) %>" />

here cpaneldetails is the object u created and listing

cpaneldetails = CpaneldetailsLocalServiceUtil.findCpaneldetailsByExitUser(userId, -1, -1);
