This case study walks through the research, dead ends, and breakthroughs — decompiling the CMP package, extending ContentReferenceEditor, proxy content items, and a custom Assets pane tab — using Wedia as the concrete example.</description>            <guid>https://techhub.iodigital.com/articles/optimizely-cms-third-party-dam-integration</guid>            <pubDate>Tue, 07 Jul 2026 00:00:00 GMT</pubDate>           <category>Blog post</category></item><item> <title>ReloadOnChange in Optimizely CMS: The Attribute Nobody Talks About</title>            <link>https://techhub.iodigital.com/articles/optimizely-cms-reloadonchange-attribute</link>            <description>Optimizely CMS has a little-known attribute that reloads the editor when a property changes — perfect for dependent dropdowns and checkboxes. Here is how I found it, proved it worked, and shipped it on a Product Detail Page.</description>            <guid>https://techhub.iodigital.com/articles/optimizely-cms-reloadonchange-attribute</guid>            <pubDate>Fri, 19 Jun 2026 00:00:00 GMT</pubDate>           <category>Blog post</category></item><item> <title>Optimizely Developers The Netherlands Meetup 2026</title>            <link>https://world.optimizely.com/blogs/william-parr/dates/2026/6/optimizely-developers-the-netherlands-meetup-2026/</link>            <description>&lt;p&gt;&amp;nbsp;&lt;/p&gt;

&lt;p&gt;For now this is a &quot;Save the Date&quot; and more details will be following (on Meetup) in the upcoming weeks once everything has been finalised. For now, expect fellow Optimizely developers and enthusiasts for casual shop talk and sharing experiences with one another, as well as some representatives from Optimizely themselves with information straight from the source &#128521; Let&#39;s just say: there&#39;s a lot of cool stuff coming our way!&lt;/p&gt;
&lt;p&gt;For more information, comment on this post or hit me up on the Optimizely Slack. We look forward to seeing you on July 1st in Den Bosch!&lt;/p&gt;
