Is there a way only one component allowed for a parsys???

[GK-AEM]

Hi All,

we have requirement that needs to allow only one component for parsys. Generally when we drag a component in parallel it will create one more empty parsys and can create  drag/drop another component but we do not want this behavior.

Is there a way to restrict like this??

Thanks,

Kishore

Go into design mode and edit the parsys to only allow for the single component you're referring to.

Customization of parsys to restrict number of compnents in CQ

1. Copy the parsys component from(/libs/foundation/components/parsys) to your poroject(/apps/<project nmae>/components/).

     2.  In the design dialog add number filed configuration to enter the number of components.

           Crate node noofcomp of type cq:widget under /apps/<project nmae>/components/parsys

              /design_dialog/items.

           Add the following properties

           xtype : numberfield

           name : noOfComp

           maxValue : 20

           fieldLabel : No of components

     3.   Create ajax.jsp and write the below logic.

           <%@page import="com.day.cq.wcm.foundation.ParagraphSystem"%>

           <%@include file="/libs/foundation/global.jsp"%>

           <%

                 ParagraphSystem parSys = ParagraphSystem.create(resource, slingRequest);

                 int totalComponents=parSys.paragraphs().size();

                 int restrictCompoNo=Integer.parseInt(currentStyle.get("noOfComp","20"));

                if(totalComponents >= restrictCompoNo){

                      out.println("true");

                  }else{

                            out.println("false");

                    }

               %>

 4.  You need to overlay the EditBase.js and Sidekick.js

          Create the following structure   /apps/cq/ui/widgets/source/widgets/wcm

         then copy the EditBase.js and Sidekick.js form libs . Place under /wcm /

         In Sidekic.js at line 4098 in set timeout method add this snippet.

            var parentPath=editComponent.path;

            var ajaxUrl=parentPath.substr(0,parentPath.lastIndexOf("/"))+".ajax";

            var notAllowToCreate = CQ.HTTP.eval(ajaxUrl);

            if(!notAllowToCreate){

                editComponent.createParagraph(definition);

            }else{

                CQ.Ext.Msg.show({

                                   msg: 'You reached  the maximun limit. You can set the limit in disign mode.',

                                   buttons: CQ.Ext.Msg.OK,

                                   icon: CQ.Ext.MessageBox.WARNING

                                });

               }

                dropTarget.editComponent.hideTarget();

         In EditBase.js at line 1181  in set timeout method add this snippet.

           var parentPath=e.path;

            var ajaxUrl=parentPath.substr(0,parentPath.lastIndexOf("/"))+".ajax";

            var notAllowToCreate = CQ.HTTP.eval(ajaxUrl);    

            if(!notAllowToCreate){

                e.createParagraph(definition);

            }else{

                CQ.Ext.Msg.show({

                    msg: 'You reached  the maximun limit. You can set the limit in disign mode.',

                    buttons: CQ.Ext.Msg.OK,

                    icon: CQ.Ext.MessageBox.WARNING

                });

            }

            e.dialogs[CQ.wcm.EditBase.INSERT].hide();

            e.insertDialogMask.hide();

I hope this would help you.

Coming to original question Allowed component is part of design. Make sure to configure the property "components" as type string[] with list of all the components.As an example for geometrixx you can refer /etc/designs/geometrixx/jcr:content/contentpage/par/@components.   Another trick you can follow is http://experiencedelivers.adobe.com/cemblog/en/experiencedelivers/2012/06/default-components-in-your...
