Paul -

I'd try a hard-delete of your local browser cache - I've seen this more than once when the JS files are updated with the update to 4.0.3.

Nice try Paul but no good the problem's still there.

Hi Paul,

I understand that you did an upgrade right before the problem occured. It's possible that some files got corrupted during the upgrade (especially when FTP'ing to a webhost.)

Try removing the umbraco_client folder (after a backup) and adding it again from a freshly downloaded umbraco 4.0.3 install.

Good luck,

Chris

I forgot to mention. I've had a similar problem some time ago:

OK solved the problem:  It was caused by using Chrome.  When I use the same dialog in FF it works fine.

Not sure what is causing the error to happen in the first place, but here is a workaround.

~/umbraco_client/tinymce3/plugins/table/js/table.js

There are two JavaScript errors that seem to happen only in WebKit browsers in the insertTable function:

O = I.elements.frame.options[I.elements.frame.selectedIndex].value;

L = I.elements.rules.options[I.elements.rules.selectedIndex].value;

Both of these  cause this error: TypeError: Cannot read property 'value' of undefined

If you look at the SELECT list for these they don't have an item selected. I tried to set selected="selected" on each of these but it had no effect. I ended up changing table.js to this:

try {
    O = I.elements.frame.options[I.elements.frame.selectedIndex].value;
} catch(e1) {
    O = "";
}
try {
    L = I.elements.rules.options[I.elements.rules.selectedIndex].value;
} catch(e2) {
    L = "";
}

is working on a reply...
