Save report error with "this.value is null"

I use code like this
Code: Select all
designer.onSaveReport = function (event) {
var jsonStr = event.report.saveToJsonString();
console.log(jsonStr);
}
But console output is
this.value is null
undefined
If I use event.report.saveToJsonInternal
I will see TypeError: this.value is null
Where is wrong? Your product are very buggy.

After some digging I see the error is from
i.addPropertyJObject("Styles", this.styles.saveToJsonObject(t))
in function ut.prototype.saveToJsonInternal
Please tell me how to fix it

And more digging,
This code work.
var report = new Stimulsoft.Report.StiReport();
report.saveToJsonString();
This code not work.
var report = new Stimulsoft.Report.StiReport();
designer.report = report;
report.saveToJsonString(); // this.value is null
Looks like report get **** after assign to desginer.

Resolved.
The reason is I'm using stireport with vue.js, and vue.js will wrap properties in designer object with getter and setter, that make `designer.styles.saveToJsonObject()` return an object not null, and that make Stimulsoft.Base.StiJson.addPropertyJObject failed.
I fixed this problem by save designer to a global clean javascript object.
Instead of
I use
Code: Select all
window.stiInstances = {};
window.stiInstances.designer = createDesigner();
