Showing different attributes of 1-1 associated object gives enormous loading time

hi all,

I want to show 40 objects in a data grid (in a caller data view). But when I try to open the single object data view wherein the data grid is placed, the browser freeze. All browsers. After a while I get in n chome a general message that the the scrip is not functioning anymore. Because of this I am not able to use the inspector to see the browser errors. One screen before there is nothing remarkable, nor in browser nor in the logging.

I notice that the JAVA consuming a lot (25%) of the local memory, so I expect that the jave fall into a deadlock or so.

The loaded objects of the data grid are made in a loop, would this cause any trouble?

So I am wondering what you guys could advice me to debug/solve this error.

In Firefox i got this message:

EDIT:.

I found now the cause; the 1-1 association. When I dont show the object from this association the data grid is loaded without problems.

So what could cause a lot of loading time for 1-1 association?
