Hello Everyone,I have a page where I am displaying a list of posts. I want to implement like and comment functionality for each post. Like Api is working well in my case but  comments are not working. I am following the approach given here https://help.liferay.com/hc/en-us/articles/360028726072-Adding-Comments-to-Your-App.
 The code in my jsp is like:
<liferay-ui:ratings className="<%=FormService.class.getName()%>" classPK="<%=aForm.getPrimaryKey()%>" type="like"/>
                <liferay-ui:panel-container extended="<%=false%>" id="formPanelContainer" persistState="<%=true%>">
                         <liferay-ui:panel collapsible="<%=true%>" extended="<%=true%>" id="userCommentsPanel" persistState="<%=true%>" title="comments">
                      
                            <portlet:actionURL name="invokeTaglibDiscussion" var="discussionURL" />
                            <liferay-comment:discussion className="<%=FormService.class.getName()%>"
                                      classPK="<%=aForm.getPrimaryKey()%>"
                                      formAction="<%=discussionURL%>" formName="form2"
                                      ratingsEnabled="<%=true%>" 
                                      redirect="<%= PortalUtil.getCurrentURL(request)%>"
                                      userId="<%=aForm.getUserId()%>" />
                        </liferay-ui:panel>
                </liferay-ui:panel-container>
Here  <portlet:actionURL name="invokeTaglibDiscussion" var="discussionURL" /> may be causing any problem? As invokeTaglibDiscussion  is deprecated in DXP 7.2. Can anyone please suggest any alternative solution to this?
Thanks in advance!!
