Bug in StretchableLayoutManager?

I’m using StretchableLayoutManager in conjunction with StretchableLayoutResizerBar to create a simple setup with two stacked tables (and the resizer bar between them). Everything works as expected EXCEPT once I move the resizer bar all the way up or down (essentially hiding one of the two tables) – the bar becomes stuck and I can’t move it anymore to show the hidden table.

Relevant code snippets:

in constructor of my main component:

layoutManager.setItemLayout(0, 0, -1.0, -0.5);
layoutManager.setItemLayout(1, 8, 8, 8);
layoutManager.setItemLayout(2, 0, -1.0, -0.5);


Component* comps = { &table, &resizerBar, &fileTable };
layoutManager.layOutComponents(comps, 3, 0, 0, getWidth(), getHeight(), true, true);
