Jit cellblock is often very odd, which makes it difficult to use despite a large options implementation.
For example, when one want to save the content of the array with the patch, the simple way is to select Save Contents with Patcher and if the data is used for a performance or a non developper user, you want also to activate the Read-only option. But actually, when the readonly is on, the jit.cellblock content is not retreived when loading the patch. Does it make any sens ? No.
In addition, you may hack the bug in writing the content on the disk, but when trying to read agin, of course (this is normal) you have to desactiveate readonly, read teh file and then reactivate readonly again.
No peace for the wicked !
