Information Selection Crash (only when loading an experiment) #351

Closed Kevin-Jay-Roberts21 closed 2 years ago

Kevin-Jay-Roberts21 commented 2 years ago

Upon creating an experiment, when a user goes through the whole process and gets all the way to the Results page, there is no issue when tapping on the graph. However, when a user loads an experiment, when tapping on the graph in the results page, the app crashes. The error message is the following:

Attempt to invoke virtual method 'double[][] com.onrpiv.uploadmedia.pivFunctions.PivResultData.getVorticityValues()' on a null object reference

The error occurs (on line 805 of ViewResultsActivity.java) because multipass is null and tries to call .getVorticityValues(). Again, this happens only when loading an experiment.

Good error report. This means we're not loading the multipass object file correctly. I'll have a fix shortly.
