Histology scoring wizard does not work

[Nicklas Nordborg]

It is not possible to register scores in the Histology wizard. To begin with everything seems to be ok, and the first sample on a glass can be scored without problems.

Clicking on the next sample doesn't move the selection to it. The original sample is still the one with the bluish background color. The name in the scoring table below the slides is updated to the sample that was clicked and the scoring information is cleared. However, entering the scores for the second sample will overwrite the scores on the first sample.

Checking the developer console in Firefix an error message appears every time a new sample is clicked:

InvalidCharacterError: String contains an invalid character

Seems like the change to a new sample is not working correctly. Some information like the name and score fields are update/cleared, then the error happens and the rest of the code that should update the selection is never executed.
