[chimera-dev] binding handlers to SortableTable checkboxes

[Eric Pettersen]

Hi Jan,
	You don’t say what the data in the table is, but one would normally deal with this by responding to the attribute change in the data rather than intercepting the table trying to set the attribute.  For instance, if your data is an attribute then change it into a property so that you can perform additional actions when the attribute is changed.  Again, I don’t know what your data is or what level of control you have over it, so I’m offering suggestions in the dark here.
