Expandablesection Collapsing Unnecessarily

I have a weird scenario with the following layout:

Selectable Table contains one or more expandable Sections (master)
Filler
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.
