Duplicate local variable contact

[Suyesh Amatya, modificado hace 9 años.]

In my view.jsp page I am getting the above mentioned error from Eclipse. However there is no duplicate variable present. When I run the portlet I get this error

An error occurred at line: 25 in the jsp file: /html/contact/view.jsp
Type mismatch: cannot convert from com.bcnet.portlet.biobank.model.Contact to com.liferay.portal.model.Contact
22: total="<%= ContactLocalServiceUtil.getContactsCount() %>"
23: />

I am using my own Contact entity the code for view.jsp is as below

<%@ include file="/html/init.jsp" %>
<%!
   com.liferay.portal.kernel.dao.search.SearchContainer<contact> searchContainer = null;
%&gt;

&lt;%
	String redirect = PortalUtil.getCurrentURL(renderRequest);
%&gt;

<aui:button-row>

Can you try this?

<liferay-ui:search-container-row
className="com.liferay.portal.model.Contact"
keyProperty="contactId"
modelVar="contact" escapedModel="<%= true %>">

When I use this, the eclipse flags the same duplicate variable error. And also other errors that the methods are undefined for type Contact.

Well, you have set results of search-container as list of Contact objects(com.liferay.portal.model.Contact) and in search-container-row you are referring com.bcnet.portlet.biobank.model.Contact.

It seems you are having custom entity named as Contact, please use service API of that entity instead of liferay's Contact entity.

In my init.jsp page

I am using

<%@ page import="com.bcnet.portlet.biobank.model.Contact" %>
<%@ page import="com.bcnet.portlet.biobank.service.ContactLocalServiceUtil"%>

And in my view I have

<liferay-ui:search-container emptyresultsmessage="contact-empty-results-message">
	<liferay-ui:search-container-results results="<%= ContactLocalServiceUtil..getAllContacts(searchContainer.getStart(), searchContainer.getEnd()) %>" total="<%= ContactLocalServiceUtil.getContactsCount() %>" />

	<liferay-ui:search-container-row classname="com.bcnet.portlet.biobank.model.Contact" keyproperty="contactId" modelvar="contact" escapedmodel="<%= true %>"></liferay-ui:search-container-row></liferay-ui:search-container>

Does not it mean I am referring to my own ContactLocalServiceUtil and not of liferay's?

[Mayur Patel, modificado hace 9 años.]

Right ! it's referring to liferay's ContactLocalServiceUtil. Please check import stmt and see it is referring to custom entity.

[Suyesh Amatya, modificado hace 9 años.]

I have following imports
<%@ page import="com.bcnet.portlet.biobank.model.Contact" %>
<%@ page import="com.bcnet.portlet.biobank.service.ContactLocalServiceUtil"%>

which means I am referring to the custom classes, no? What I am missing here?

[Mayur Patel, modificado hace 9 años.]

imports are correct. this will only conflict when you are having two different jars having same model class inside same package.

New to liferay so dont quite know how to resolve this. How can i get over this issue?

[Suyesh Amatya, modificado hace 9 años.]

The problem seems to be the contact variable in modelVar="contact" is already in use by Liferay and of type com.liferay.portal.model.Contact. So when I try to define the contact variable as com.bcnet.portlet.biobank.model.Contact it was showing the mentioned error.

The solution was to give the modelVar attribute some value other than contact say like "biobankContact". So something like this

<liferay-ui:search-container emptyresultsmessage="contact-empty-results-message">
	<liferay-ui:search-container-results results="<%= ContactLocalServiceUtil.getAllContacts(searchContainer.getStart(), searchContainer.getEnd()) %>" total="<%= ContactLocalServiceUtil.getContactsCount() %>" />

	<liferay-ui:search-container-row classname="com.bcnet.portlet.biobank.model.Contact" keyproperty="contactId" modelvar="biobankContact" escapedmodel="<%= true %>"></liferay-ui:search-container-row></liferay-ui:search-container>

Then it resolves the issue.

Good to know this, Thanks for the info Suyesh
