IUpdater doesn't fire after reloading a title block family

[ivo.lafeber]

I have a Title block family in my sheet, the title block has some sheet parameters. 

The sheet number parameter get updated with an parameter updater, which joins a couple of parameters to one sheet number. 

When I reload / update the title block from the network with "overwrite the existing version" option, the parameter IUpdater is not working anymore for the titleblock. 

the parameter updater still works for all the other families in the model. 

Alos when I insert an electrical fixture the parameter updater works, when I reload / update the electrical fixture the updater still works for the electrical fixture. 

After closing and opening the model the title block is updated with the parameter updater as it supposed to.

ok, so You will probably need to debug this updter, it can be some kind of bug and until you will not catch this error Revit will just eat it and not show anything.
I can only speculate because there is no code. maybe reloading type make some element been recreated and you still trying to refer to old one , or you take something from Symbol that was not activated.

I have debugged the add-in, there is no error generated which I can use to solve the problem. the IUpdater just doesn't get fired anymore after updating the title block.

did you try to unregist and regist updater? if after that it still not working for only this one tile it may be a problem of filter set up for updater.

I have not unregist and regist the updater, the other families don't give these problems, If I for instance insert an electrical fixture the IUpdater works fine, if I update that fixture the IUpdater still works fine, only when I update a TitleBlock the IUpdater does not get fired, it's only as a workaround that a unregist and regist should be needed in my opinion.
