Load empty data crashes chart

[yorl1n]

Ext version tested:

• Ext 6.0.0 rev 640

Browser versions tested against:
All

Description:

After trying to load empty data in chart and then load normal data Uncaught TypeError: Cannot read property 'calloutOriginal' of undefined
message is thrown in console. After that there is no way to load any data.

Steps to reproduce the problem:
Fiddle

1. Open provided fiddle.
2. Press Load data button -> data loads normally.
3. Press Load empty button -> looks like empty data is loaded normally.
4. Press Load data button one more time.

The result that was expected:

Data loads normally as for step 2. To see what is expected launch the fiddle with ExtJs v.5.1.1
The result that occurs instead:

Uncaught TypeError: Cannot read property 'calloutOriginal' of undefined
exception is thrown. Data stops loading.

The same happens when load data with n records in store and then load data with parameters < n.
So when number of items decreases the chart crashes.

Thanks for the report! It looks like this issue has been resolved for the next release of Ext JS 6.

Thanks!

I'm developing an OpenSource project with ExtJS 6.0.0 and I'm suffering with this problem for over a month now.
I just found this post!

Since Sencha don't care that much to update the GPL version, there is some known workaround I can apply now to my project?

Thank you.

I ran across this, or a similar error in the same 6.0.0.640 build when reloading the store with a smaller set of data (as mentioned in comment #2). The workaround for me was to not specify the labels (which has the side effect of no legend), but does allow the chart to load. Specifically, with the labels enabled, I get the following errors when reloading the store with the smaller data set:

Uncaught TypeError: Cannot read property '0' of null (on Instancing.js line 172)
followed by SEVERAL (one for every mouse move!) errors that say:
Uncaught TypeError: Cannot read property 'orientation' of undefined (on PieSlice.js line 180)

Will the fix specified in EXTJS-18512 also correct the case I've described?
