Hi Timothy, I solved my little problem. I added an onclick event at my Textfield and stop the propagation of that event.
function ProcessEvent (event, eventName, elementName, stopPropagate) {
var target = event.currentTarget.localName;
var type = event.currentTarget.type;
if (stopPropagate && target == "input" && type == "text") {
if ('bubbles' in event) { // all browsers except IE before version 9
if (event.bubbles) {
event.stopPropagation ();
}
}
else { // Internet Explorer before version 9
// always cancel bubbling
event.cancelBubble = true;
}
}
}
...
onclick="ProcessEvent (event, 'onclick', 'textField', true);"
Now all is fine.
