TYPO3 Core

I tested it on 7.6.2

Please try 7.6.5 (which is a security release)

Same behavior with typo3 7.6.5

The names of the forms are changed between TYPO3 version 6 and 7. In changed the javascript file rtehtmlarea/Resources/Public/JavaScript/RteLinkBrowser.js

    RteLinkBrowser.changeClassSelector = function() {
        if (document.lclassform.lclass) {
            document.lclassform.lclass.value = document.lclassform.lclass.options[document.lclassform.lclass.selectedIndex].value;
            if (document.lclassform.lclass.value && RteLinkBrowser.HTMLArea.classesAnchorSetup) {
                for (var i = RteLinkBrowser.HTMLArea.classesAnchorSetup.length; --i >= 0;) {
                    var anchorClass = RteLinkBrowser.HTMLArea.classesAnchorSetup[i];
                    if (anchorClass['name'] === document.lclassform.lclass.value) {
                        if (anchorClass['titleText'] && document.ltitleform.ltitle) {
                            document.ltitleform.ltitle.value = anchorClass['titleText'];
                            document.getElementById('rtehtmlarea-browse-links-title-readonly').innerHTML = anchorClass['titleText'];
                        }
                        if (typeof anchorClass['target'] !== 'undefined') {
                            if (document.ltargetform.ltarget) {
                                document.ltargetform.ltarget.value = anchorClass['target'];
                            }
                        } else if (document.ltargetform.ltarget && document.getElementById('ltargetrow').style.display === 'none') {
                            // Reset target to default if field is not displayed and class has no configured target
                            document.ltargetform.ltarget.value = RteLinkBrowser.defaultLinkTarget;
                        }
                        break;
                    }

                }
            }
        }
    };

Now the style selector works.

Please consider using proper syntax highlighting (pre tag) for code. Thanks.

Not working with 7.6.9, php 5.5.26 ?

I applied 48714 to two different installs of Typo3 7.6.9 and it does not change a thing.
Is something else needed?
Urgent thanks.

Tested on 7.6.14 out of the box, not working:
Does 7.6.14 need this patch?
Do i have to apply it there, too?
Do i have to apply something else?

having the same problem / behaviour using 7.6.13 / 7.6.14 - this should be really fixed since Editors don't care about this and assigning titleText should work out of the box!
