When you add CREATION DATE and MODIFIED DATE as wizards to the table, you are unable to click on the SAVE icon when they are dragged into the table

Cleared all browser caches, reloaded builder, tried on multiple projects

I just went back into a table where I could not save these fields, and the fields are actually there, however the fault is replicable still. The SAVE icon appears to do nothing, but it looks like it is doing what it is supposed to, you just need to close the table and reopen it to make sure the field has saved

I saw a bug there is that the field is not aliased correcly. Are you sure the field name is acceptable ?

Because if save do not work it might be because of that. And the red border is not visible because the focus is on it.
Improvements possible...

I just created a brand new project called TEST

I created a table called TEST and started to add a load of WIZARD items. All saved fine except

Creation Date ( alias creation-date)
Modified Data (alias modified-date)

Do not appear to save, however if you close the table and reopen it, they have actually save.

If I then EDIT those fields, again, the save icon appears to do nothing

I have updated my Java to the latest version (Version 8 Update 45).,
cleared all my history, settings and cache,
Using Chrome Version 42.0.2311.152 (64-bit) on a Mac

Arrgghh big issue !!!

It should not be able to save a field containing a '-' in the name. Very bad.

Ok. So I understand the problem.
Will fix that later in the day.

That name is auto generated, I didn't create it

Fixed now
