I found an breaking change in version 20193.245 and 20193.258
We have a few Combobox/MultiSelect controls with remote bindings.
That works fine until we update to 2019 v3.
The data will not load anymore and the collectionView property returns null, so the refresh method cannot be called.
function filterChanged(sender) {
var multi = wijmo.Control.getControl("#UserMultiCombo");
if (multi != null) {
var cv = multi.collectionView;
cv.refresh();
}
}
<c1-multi-select id="UserMultiCombo" checked-member-path="Assigned" display-member-path="Name" placeholder="Select users" header-format="{count} users" drop-down-css-class="multi-column" show-drop-down-button="@(Model.Mode == ActionEditMode.Create)" is-disabled="@(Model.Mode != ActionEditMode.Create)" checked-items-changed="changedAssignedUsers">
<c1-items-source read-action-url="@Url.Action("GetAvailableUsers")" query-data="QueryData" disable-server-read="false" collection-changed="changedAssignedUsers"></c1-items-source>
</c1-multi-select>
