android - Scichart can't remove annotation -


when im trying remove annotation, i’m receiving error:

java.lang.nullpointerexception: attempt invoke interface method ‘void com.scichart.charting.visuals.annotations.iannotationplacementstrategy.drawadorner(android.graphics.canvas)’ on null object reference @ com.scichart.charting.visuals.annotations.annotationbase.ondrawadorner(sourcefile:889) @ com.scichart.charting.visuals.annotations.adornerlayer.ondraw(sourcefile:144) @ android.view.view.draw(view.java:17071) @ android.view.view.updatedisplaylistifdirty(view.java:16053)

i’ve tried many ways, like:

updatesuspender.using(pricechart, new runnable() {     @override     public void run() {         pricechart.getannotations().clear();     } });

and

updatesuspender.using(pricechart, new runnable() {     @override     public void run() {         pricechart.getannotations().remove(myannotation);     } });

but can't remove it.

that's weird. there's scichart android tutorial on annotations here. uses 'chart.getannotations().remove(0)'

the full source code tutorial can found @ scichart.android.examples github repository.

does work you?

qa guys complained can't automate frontend testing. because our html looks same outside. lazy hack did this <template> <div :role="$options.name"> ... </div> </template> <script> export default { name: 'vmcomponentname' } </script> which takes name script , applies html. in browser get: <div role="vmcomponentname"> ... </div> line :role="$options.name" goes in every component. is there dry er solutions? please share. additional details i'll explain in details looking for. imagine have vmusercreate form creates user. test case can create user . to automatically test without role, have use following selector: .wrapper > .wrapper > .wrapper > .submit-button the test extremely brittle (will break lot). if use roles can use [role="vmusercreateform"] .submit-button selector. many folds less brittle. so basically, i'm ...
