RE: Re[5]: No proxy description found for oid...

Hi Dejan,

OK, then let's investigate more.

First of all: what ULC version are you on
(from the stacktrace it looks like ULC 6.0.x)? What JDK?

The general problem is a follows: ULC tries to lookup a component
with a special ID on the client side but it cannot find it. This happens
while a tree of other components is being initialized on the client side.

A potential source of problems could be extensions:
did you write any extension and are are they used in the context of the
error?

It would be very helpful if you could isolate the problem via
a code snippet, otherwise it is very difficult for me to track this.

The least you should do is to turn on the LOG level FINEST
(see the ULC docu on how to do this) and send the LOG which produces
the error.

Greetings,

Daniel

hi daniel,

we're aware of the problem of the static fields.
(thats why i have scanned all the code for it)

i can really tell for sure that i also do not reference a static object
indirectly.
i have checked all static variables in our code. there are only a few non
primitive statics which have
nothing todo with ulc.

i'm working with singletons but they always create new instances of the
objects.

DP>>> hi,

DP>>> we have developed an own ULC extension for showing modal dialogs.
