Dear Wijmo Team,
I’m struggling to send data to a server. When editing an item, the change in the collectionview is corretly stored. But when calling a save function, the change in the collectionview is lost.
Change method called by button click
- parameter item is an item from the collectionview
- gridData is the collectionView that is created as a component property
like so: public gridData: wjcCore.CollectionView = new wjcCore.CollectionView();
change(item) {
this.gridData.editItem(item.date);
item.date = this.date;
this.gridData.commitEdit();
item.dirty = true;
this.gridData.refresh();
console.log("gridData: ", this.gridData); //here everything is fine
}
Async function to send data to server
async save() {
//here the change is already lost, even the dirty flag is gone
console.log("gridData: ", this.gridData);
for (let i = 0; i < this.gridData.items.length; i++) {
let tmpItem = this.gridData.items[i];
// even though the dirty flag is gone the code successfully passes the if statement
if (tmpItem.dirty === true && tmpItem['id']) {
console.log("tmpItem: ", tmpItem); // the single item that was changed, but the change is lost
let convertedItem = Utils.convertFromNative2Katalogwert(tmpItem, this.katalogAttributeMap);
updatedItems.push(convertedItem);
}
}
This is kind of strange. It seems like there is a second instance of gridData flying around but I have no idea why.
Do you have an idea why this might happen?
Best regards
Moritz
