WebGL: INVALID_OPERATION: getBufferSubData: no buffer

When I click a point on a loaded project I get the following error

News on this?

In my case, if the loaderSettings.generateLineRenders option is turned OFF and you pick an element
-> then the GeometryLoader.processPreparedBuffer() method will not prepare the lineIndices for the buffer
-> the FrozenBufferSet.lineIndexBuffer will be undefined or null
-> binding that lineIndexBuffer to WebGL will be failed and there will be no buffer to run createLineRenderer

I handle this error by:

• Workaround: Always set the loaderSettings.generateLineRenders option to true
• A check for lineIndexBuffer at the start of AbstractBufferSet.generateLines() is needed. But then you will have no way to indicate that this element is selected. So always changing the selected element's color might be a good idea.
