Expandablesection Collapsing Unnecessarily

I have a weird scenario with the following layout:

Selectable Table contains one or more expandable Sections (master)
One or More Tables listening to changes in the above table

Selectable table (master) has serverSide boolean set to true.

When I click on any expandable section in the master table then the section expands and then collapses automatically. If I turn off the serverSide flag or remove the listeners the section stays expanded.

Any clues on how to fix this?

PS I realize many may be switching to Echo2 but I am working with Echo1.1.4 + Echopoint 1.0

Thanks for any pointers.
