This doesn't surprise me. If I recall, the selection management
directly modifies the in-memory dataset, so if you have two bindings
of the same dataset, the selection management is likely to get
confused. The selection manager for lazy replication is a little more
careful (since it cannot rely on the selected item being in memory),
but I think it also has some bugs.
This would be a good project for an external contributor: to rewrite
the selection manager to maintain it's own state an not to modify the
dataset. Then there would only need to be one selection manager
implementation -- you would not need a different one for lazy
replication.

Hello everyone,
if I bind two grids on the same data I get very strange and
inconsitent
behaviour with selections.
I'm using OL 4.3 and my dev box is running flash9 on firefox for
linux.
Firstly I'm not allowed to select the same row in both grids and after
trying, the behaviour is even more bizarre. It's hardly explainable,
please try it out and let me know if this is a known issue/feature/bug
because I wasn't able to find anything about it.
Thanks a lot for your support,
M.
This is the example code which is actually a small augmentation of the
example on the OL reference page:
<canvas debug="true">
<dataset name="contacts" request="true"
src="http://www.openlaszlo.org/lps/demos/contacts/
contactsdata.xml"/>
<simplelayout axis="y"/>
<grid datapath="contacts:/resultset" id="g1">
<gridcolumn showheader="false" width="50">
<view bgcolor="#CCCCCC" width="${parent.width}"
placement="header" height="${parent.immediateparent.height-1}"/>
<text datapath="position()"/>
</gridcolumn>
<gridcolumn width="200"> Name
<text datapath="@displayname" resize="false"/>
</gridcolumn>
</grid>
<grid datapath="contacts:/resultset" id="g2">
<gridcolumn showheader="false" width="50">
<view bgcolor="#CCCCCC" width="${parent.width}"
placement="header" height="${parent.immediateparent.height-1}"/>
<text datapath="position()"/>
</gridcolumn>
<gridcolumn width="200"> Name
<text datapath="@displayname" resize="false"/>
</gridcolumn>
</grid>
</canvas>
