iFix: CFixPicture_Initialize is flaky

Sometimes I come across screens that have a rather sizable amount of code in the Initialize event of an iFix picture.

In one case, the the author was setting a digital register.

In another, the author was creating objects, setting them to a database tag, and reading the value, and manipulating pull down boxes or text displays based on the read value (this also involved TagGroups)

In the former case, the script would sometimes fail to update the database DR tag.

In the latter, sometimes the picture cannot evaluate the tag and fails to load properly.

Generally I've found that the Initialize event can't be relied upon to do intensive tasks. My hypothesis is that the Initalize event is happening too quick for things to register with the iFix database, but I could be wrong...

Has anyone else come across issues like these?

i have a picture with a lot of code propagating combo boxs with sql server trans actions. so far i haven't had a problem. I did seperate the code from being in the initialize event by making it it's own module and the initialize event calls the procedure in the module.

Hmm, perhaps it is our network setup. I've done what you have said as well, and sometime the initialize event will fail to call the subroutine I partitioned the other code into.

ahhh yes now i remember, i had a similar issue. Disable caching on that picture and that should take care of it.

Interesting...I will give that a try, thanks.

What is it about loading from the cache that would cause this? Does Initialize not like to run properly when fetched?

I dont know why it would be different but I have two pictures that don't load properly if they are cached.
