Just wanted to know if anyone has run into this problem or knows why this is happening.
I am doing a really simple mvvm test application. Everything works.
The only problem is that I have a DB with 4588 records and when i try to pull them all, my loadoperation craps out.
If I narrow it down to .take(4095), this works. So my Computer Science Spidy Sense started buzzing. I know this number. It then dawned on me that 4095 ( 4096 records actually since the collection is 0 based) is 8^4 or in other terms 32bits. Is this a built in limitation in RIA? 32 bits? ..or just a good CS round number that was used to cap the calls?
So then I decided to try it another way using a custom domain service and a presentation model.
The wierd thing is that I was able to get all 4588 records.
That also had issues, for instance I was only able to hang 12 properties off of my presentation model. Once I added another property, it broke. But the original problem of 4096 record limit wasn’t showing up with the PM.
Any ideas?
Thanks in advance!!!
It’s possible you are running into the default limit for MaxItemsInObjectGraph, I’ve used the approach given here to resolve in the past:
