after copy & paste parameters, "please select parameters to fit"

[richardh]

after copy & paste parameters, "please select parameters to fit" appears when you hit fit, have to deselect and select fitting parameter check boxes.

After any modifications to a model (e.g. add or remove an S(Q)) the selected "fit" check boxes are ignored?

[butler]

a bit more sleuthing and seems that for parameters that are copied the state of the checkbox is also copied but is not passed to the model so that the model always thinks it is unchecked. If the parameter is not copied its state is not changed so if checked will be properly seen as checked.

Then there is the problem that if a model is selected with some parameters checked and a new model (either a new one or as a pq*sq any checked parameters are not recognized by the model and pressing fit throws up a "you must select parameters to fit" error. This is probably a result of the change that all parameters are unchecked by default when choosing a new model.

It looks like wx doesn't update the model on view change and requires refreshing. Should be pretty easy to fix.
