viewer.onInteraction async

[Vardenis]

Hello,

I'm trying to get async data within onInteraction function by variables, but if data comes a little bit too late, the report won't show it and the async things actually doesn't help.
Not sure what is happening under the hood, but if I'm not setting slower internet it gets data in time and shows correctly, but if I slow down the internet even a bit it doesn't get it in time and the regData() and synchronize() functions won't do anything for me.

The code looks something like this

Code: Select all

	viewer.onInteraction = async (args) => {

                if (args.action == "Variables") {               
                     
                    await this.httpService.getData("whateverlink").toPromise().then((result) => {

                        const dataSet = new Stimulsoft.System.Data.DataSet();
                        dataSet.readJson(result.data);

                        report.regData("data", "data", dataSet);
                        report.dictionary.synchronize();
                    })
                }
            }

I've also tried function args.async = true, but then I'm not quite sure how to end async method, cause it starts showing spinner on the beginning and it never ends.

P.S. I'm using Angular, but it shouldn't be the reason

Hello,

Thanks! That did the job

Also I had to add args into callback method to pass them back

Code: Select all

callback(args);
