undefined in v3.1.2

Hi,

I'm thinking this issue could be caused by calling the update function before the plugin is fully initialized (i.e. before the asynchronous render function has completed).

I expect your javascript code looks something like this:

const viewerContainer = document.getElementById('myViewer')!;
const viewerInstance = new PDBeMolstarPlugin();
viewerInstance.render(viewerContainer, initOptions);
viewerInstance.visual.update(newOptions, false);

Try to change it to something more like this:

const viewerContainer = document.getElementById('myViewer')!;
const viewerInstance = new PDBeMolstarPlugin();
viewerInstance.render(viewerContainer, initOptions).then(() => viewerInstance.visual.update(newOptions, false));

Also, updating to version 3.1.3 could help.

Or alternatively

const viewerContainer = document.getElementById('myViewer')!;
const viewerInstance = new PDBeMolstarPlugin();
viewerInstance.render(viewerContainer, initOptions);
viewerInstance.events.loadComplete.subscribe(() => viewerInstance.visual.update(newOptions, false));

Hi,
thank you very much for your reply. I tried both solutions which you provided including using v3.1.3. The following kinda worked:

viewerInstance.render(viewerContainer, initOptions);
viewerInstance.events.loadComplete.subscribe(() => viewerInstance.visual.update(newOptions, false));

Both structures got loaded but then the coloring was weird. The colors of the chains we jumping and changing by themselves :) I guess i would have to change my coloring functions as well in order to make them work with the new version of the plugin. Too much work to do tho haha. So for now i will stick with v1.2.1 of the plugin as everything works well with it.

Thank you again for your time and help!
