Example given here -
to overwrite the built-in link configuration dialog box by adding a field to set a link title:
http://forums.adobe.com/thread/1230814

Very important to compare the code given in the example for changes.

Overview:

1. Setup in the apps director to create a "widgets" folder with these values
• jcr:primaryType  = cq:ClientLibraryFolder
• sling:resourceType = widgets/clientlib
• categories = cq.wcm.edit
2. Create a js file that overrides the built-in js plugin, note:
• Initialize the name of the plugin
• Register the name to the built-in xtype
• Uses CQ.form instead of CUI.
3. Create a js.txt and include the name of js file within

Adobe CQ/AEM Query Builder - empty property

So at work, I was faced with a scenario where I have to use the CQ query builder to retrieve a bunch of articles that when they do not have a date property it will be selected along with the ones with date property that does not expire.

A little pseudo-code to show what I mean:

if (!article.hasDate) {
  return true;
} else {
  if (article.date >= now()) {
    return true;
  }
  return false;
}

Here are some articles I found online before I came up with a solution:

• http://labs.sixdimensions.com/blog/2013-07-10/custom-predicateevaluators-or-how-i-learned-stop-worrying-and-love/
• http://www.wemblog.com/2013/04/how-to-create-custom-query-predicate-in.html

Finally, here is what I have in CQ query builder:

path=[path/to/articles]
type=cq:Page
99_property=@jcr:content/cq:template
99_property.value=[apps/path/to/template]
10_group.p.or=true
10_group.1_property=@jcr:content/offTime
10_group.1_property.operation=not
10_group.2_daterange.property=@jcr:content/offTime
10_group.2_daterange.lowerBound=[current-date-or-hardcode-date-for-testing]
10_group.2_daterange.lowerOperation=>=

This is now returning articles that does NOT have the offTime property; also it returns articles that DO have the offTime date and are current.

Adobe CQ/AEM package install behaviour - filter.xml

Encountered a problem that whenever a package is deploy / installed, it will overwrite existing content and folder structure that was setup.

Using the filter.xml under META-INF/vault, we can configure it in a way that it keep existing content intact.

http://www.wemblog.com/2012/04/how-to-change-package-install-behavior.html

There are three Modes available:

1. replace: Normal behavior. Existing content is replaced completly by the imported content, i.e. is overridden or deleted accordingly.
2. merge: Existing content is not modified, i.e. only new content is added and none is deleted or modified
3. update: Existing content is only updated but never deleted

Add it under META-INF/vault/filter.xml

<?xml version="1.0" encoding="UTF-8"?>

<workspaceFilter version="1.0">
    <filter root="/content" mode="update"/>
</workspaceFilter>

Advance package filtering include / exclude regular expression

Example META-INF/vault/filter.xml

<?xml version="1.0" encoding="UTF-8"?>

<workspaceFilter version="1.0">
    <filter root="/content" mode="update">
        <include pattern="/content/foo/bar/*"/>
        </filter>
</workspaceFilter>
