The function called by the subscription function triggers twice.
The publisher is not being used in an activate or attached function, but in an async function of a different class. Both classes recieve the same EventAggregator through binding. Console.Trace() has the same routes in both cases. The Publish/Subscribe set is unique and not used by any other classes.
async sender(item:any):Promise<void> {
this.dialogService.open({
viewModel: CaModalConfirm,
model: {
color: this.color
}
}).whenClosed(async response => {
if (response.wasCancelled === false) {
this.moduleName = params.params.moduleId;
await this.selectionEventAggregator.publish('requestSelection',{item: item});
this.elementEventAggregator.publish('hideSidebar');
}
});
}
