Breaking: #73044 - JSON for ClickMenu in Backend¶
See forge#73044
Description¶
The ClickMenu in the TYPO3 Backend now uses JSON to transport data between the server and the client.
Before, a proprietary <t3ajax> syntax with XML was used to transport the contents of the ClickMenu.
Impact¶
Using ClickMenu to implement a custom ClickMenu JavaScript handler instead of the default ClickMenu.js could result in unexpected behaviour.
Affected Installations¶
Installations with extensions that use custom ClickMenu.js behaviour.
Migration¶
Adapt the custom code to handle JSON responses instead of XML responses.
