Im using adobe CQ 5 and I have created a bunch of components.
For all these components I have set allowedParents to */parsys and I have defined the componentGroup as xyz.
My page contains the parsys component. When I enter the parsys design mode, the list of allowed components does not show the component group xyz.
Please help! Thanks in advance
Kindly make sure that your components jcr:title is not the same as the component's name. For Eg: if the name of the component is text, then the title should at least be Text and not text. Change it and then check in the design mode, it will list your component group.
If your component does not have dialog then child node cq:editConfig enables the component to show in the sidekick. for more please visit http://www.cqtuts.com/cq5/cq5-component.html
1.Please verify your Jcr:title (text) does not match with your component name.A difference need to mentioned i.e., if your component name is Title,then your Jcr:title should have title.
If the component is not adding in sidekick after doing the above,then add this tooo 2.Add Cq:editConfig to your component.This will enable you to add your component in sidekick.There is no need to create a dialog.
