Hi,

I've a tree of multiple objects but the links with the others classes take a few moment to load.
therefore i would like to exclude an association .

Thanks

lazy="true"?

no, lazy="true" and explicit proxy is insufficient..

When i call, by DWR, the class i wait too long... (through the debug log, i can see that "DWR" converts all elements from the collection)

So i would try to exclude the List from the loading (just for this page).

Fair enough. Have you tried listing the exclude from the loading?

Yes but if that works I would not be more advanced (because i need this collection from this class in other page)

i try, two second.

Benchmark (load of a tree):

With the collection mapped in myClass.hbm.xml -> 3s
When it's unmapped -> 1.2 sec

EDIT:

collection mapping

<bag name="communications" table="Communication" lazy="true" inverse="true" >
<key column="entityLink"/>
<one-to-many class="org.X.X.Communication"/>
</bag>

You're welcome.

But i'm not more advanced, i need this collection from this class in other page.

For the benchmark, i removed the declaration of the collection from the file myClass.hbm.xml ...

But it isn't what i want, i need to exclude the load of a collection in the query.
I don't want to remove this collection from the class.
