# v 4.2.3: linebrake behind CDATA lost, JavaScript not processing

 * After embedding the call of a JavaScript function into a post/page the Text view
   of the editor shows:
 *     ```
       <script type="text/javascript">// <![CDATA[
       myFunction();
       // ]]></script>
       ```
   
 * When calling this page by its URL its HTML code looks like that since today –
   23 July 2015:
 *     ```
       <script type="text/javascript">// <![CDATA[  myFunction();  // ]]></script>
       ```
   
 * … all in a single line. And the JavaScript function is not called.
 * Saving the HTML code as static page and inserting a line break before `myFunction()`
   solves the problem, the function is called again.
 * And this problem comes up with all pages having JavaScript embedded this way –**
   all of them are drop dead now** – without having edited any of them since days.
 * As the only change to the WordPress system was the update to 4.2.3. last night
   we are quite sure that this version starts flattening embedded CDATA code.

 * Same problem here, though the workaround I found was to change from using line
   comments “//” to comment block “/* */” and all is good.
 * e.g. OLD code
 *     ```
       <script type="text/javascript">// <![CDATA[
       myFunction();
       // ]]></script>
       ```
   
 * NEW code
 *     ```
       <script type="text/javascript">/* <![CDATA[ */
       myFunction();
       /* ]]> */ </script>
       ```

 * Don’t work in all case. In my code this:
 * `sParameterName[0]`
 * is change as:
 * `sParameterName[0&#093`
 * As a result the code is wrong.

 * I am getting this error in 4.1.6 suddenly.
    This
 * <script>// <![CDATA[
    alert(‘hello’); //]]> </script>
 * gets converted to
 * // <![CDATA[ alert(‘hello’); // ]]>
 * and the js code doesnt execute. I had an embedded twitter feed in my site which
   has stopped working because of this.
