Hi, I have a list in a gallery showing filtered items of a table and a formular to create a new entry or to modify one.

When i choose an item of the list, the item is put in the context variable ctxMission, which works fine.
When i want to create a new entry, the variable is set by
UpdateContext({ctxMission:Patch(Defaults(Table);{numMission : XXX; ordre : XX} ) })
Unfortunately, it does not seem to work, as IsBlank(ctxMission.ordre) returns true. But strangely, when i go to the variable information, there is actually a value in the field ordre so that the previous test should return false.
Do you know what could be the reason ?
Thanks in advance,
