Liferay : Solution:Error while integrate Liferay OOB comment functionality with MVC portlet ?

Hello There,

            Couple of days ago I was working with MVC portlet and I had to integrate comment [<Liferay-ui:discussion ….> tag] functionality with it in Liferay [6.1 GA2]. I thought it would be cake walk for me but no it was not L, cause simple way this is working very well but not with search-container or I guess not within for loop.

I tried to get ans. from various place but could not get it.

Problem description:

Step 1) Create MVC portlet.
Step 2) view.jsp which contains search container.
Step 3) In each row of search container I kept below code.

<portlet:actionURL var="discussionURL"  name="invokeTaglibDiscussion"></portlet:actionURL>
 
 <liferay-ui:discussion
                 className="<%=objEntry.class.getName() %>"
                 classPK="<%= obj.getEntryId() %>"
                 formAction="<%= discussionURL %>"
                 formName="fm2"
                ratingsEnabled="<%= false %>"
                redirect="<%= currentURL %>"
                subject="<%= obj.getTitle() %>"
                userId="<%= obj.getUserId() %>"
               
            />

Step 4) Deploy portlet and check js console of browser I was getting two errors as describe below

Java script Error 1)

“TypeError: document.****************_parentMessageId0 is undefined”

Resolution:

-    It was OOB issue and since we were using EE version we got patch for above error.

Java script Error 2)

“TypeError : d.one(…) null” [Please find screen shot for same.]

 

Resolution:

-        After even applying patch I was facing error-2,so debug further and

Found following solution

Reason:

While you are using <Liferay-ui:discussion…/> tag inside the for loop or inside the search container that time "formName" always remain same in mine case its always "fm2" that the issue.

Solution:

Try to keep “formName” element unique with primary key of that object,
Following code worked for me in mine case, you can use the same.

<portlet:actionURL var="discussionURL"  name="invokeTaglibDiscussion"></portlet:actionURL>
 
        <liferay-ui:discussion
                 className="<%=objEntry.class.getName() %>"
                 classPK="<%= obj.getEntryId() %>"
                 formAction="<%= discussionURL %>"
                 formName="<%= primaryKeyOfMyObj %>"
                ratingsEnabled="<%= false %>"
                redirect="<%= currentURL %>"
                subject="<%= obj.getTitle() %>"
                userId="<%= obj.getUserId() %>"
               
            />

Hope this helps.
