How to repeat: Go to group definitions, create a new one. Edit the condition and open the expression builder using the "+" icon. Fill in a Value of "hithere" and leave the other fields the same. Click "Add Expression". Notice the value field is ignored. Workaround - click in the blank area of the expression builder to defocus the textfield, then click ok. Or - add the value on the right hand side of the expression, outside of the expression builder.
rev2473 - use javascript keypress callback handler along with client side timeouts to get around requirement to defocus the 'value' input text field
Fixed, rev2522
