The fix of issue ICE-10518 seems unneccacery.

The fix causes the problem that it isn't possible to disable blockUI for a specific form, if the context parameter 'org.icefaces.blockUIOnSubmit' is set to true.

Because ace:submitMonitor can be placed on every form, it should overwrite the context parameter org.icefaces.blockUIOnSubmit, which only can be disabled for specific pages.

Another way to fix the bug ICE-10518, is to not use the attribute blockUI="@none" on the element ace:submitMonitor, if you want the blockUI to appear. If you want an blockUI to appear then you don't even have to use the element ace:submitMonitor, or you don't need to specify the attribute 'blockUI'.

The one who posted the question said the fix already in his description: "Removing the ace:submitMonitor from the page allows the ui blocker to work correctly. ". He should have just removed the ace:submitMonitor, and the ui blocker allways worked correctly, the use of ace:submitMonitor was only faulty used.
