data change bug in viewer

[ychyss]

I test this bug on dwv/tests/pacs/viewer.js example. version 0.32.0

Steps:

1. Select one series (vhf head data) in single layout
2. Do some interations(scroll it or click it)
3. Change view layout to MPR
4. Press 'Reset Viewer'
5. Open new series (vhf hip data) in MPR layout

the view layer looks like at wrong direction ... (no error log. even when I open series in MPR layout first time)

6. Click view layout to single
   got error: Cannot initialise layer with data id: 0

the stack info is here:

I also found this bug in my project, and I avoid this bug by deleting whole dwvApp object and store the dicom files data into a custom array, and then set new data into a new dwvApp instance manually(do not use reset).

Sorry, I can't reproduce. What do you mean by 'Reset Viewer' in step 4?

[ychyss]

Sorry for that, I mean call app.reset() method using a button.(https://ivmartel.github.io/dwv/doc/stable/App.html#reset)
