Hello again!
OK, at least I figured out (with a little help :) ) why the
checkox-glitch occurs: The value of the checkbox was not stored in a
dataset. I used the onvalue-handler to update the data in the dataset.
The sad thing is, that I have to have an additional TAG in my XML to
have use a checkbox in my object... but anyway: That workaround does the
trick for me!
It may very well be, that my second question solved itself, but my third
question still stands: will I encounter problems, when I try to display
informations from another dataset?

Hi List!
I experienced a strange behaviour when I tried to use some fancy
LazyResizeReplication to boost my applications performance compiled
with OL 4.3. I want to display a large set of Inboxentries (could be
more than 200 or 300 entries) - each of these replicated Objects is a
view that contains several Icons, Buttons, Text-Elements and, last but
not least, a checkbox to mark this item.
First of all: When I mark one item and scroll down, suddenly other
items are selected as well... at least their checkbox is appareantly
(Have a look at the code-example below). Is this a glitch or am I
missing somethin important?
Second thing: When I scroll down, the data of the Items is not changed
correctly (not in the attached example, but in my "big" application
which is a little bit more complicated). Is this a common issue and
how do I avoid that? It seems, that the same kind of Objects is rolled
over an over again - but surprisingly the marked checkbox appears at
different items. Very strange and seriously anoying...
Third question: I am replicating the Objects in my inbox using a
dataset, which is filled during the startup of the application
(servlet call). But in my Objects I have to display some more
Information which is not located in my "inbox-dataset" but in my
addressbook - such as name of the sender of the message. In the
developer guide you can read somethin like "All displayed data has to
be provided through the underlying dataset - if you change information
you should store the changes in the Dataset". But what does happen if
some of the displayed data is not locatet in the dataset which
triggers the replication?! Please don't tell me to add datanodes to
the replication-dataset, that are copies of the other dataset to
display their information :)
So, any thoughts? See the attached File for further information!
