I've created a widged with Orchard. Unfortunately I've used the same "Title" for a jPlayer widget twice. Now I receive an error:
Server Error in '/wgk' Application.
Sequence contains more than one element

In MediaGallery.cshtml (found in error description above) is written:
@model Orchard.jPlayer.Models.MediaGalleryPart
<fieldset>
<div>@Html.LabelFor(o => o.MediaGalleryName, @T("Media gallery"))</div>
@if(!Model.HasAvailableGalleries) {
<div>@T("You need first to create an media gallery on Media Gallery menu")</div>
}
else {
<div>@Html.DropDownListFor(o => o.SelectedGallery,
Model.AvailableGalleries)</div>
<div>@Html.LabelFor(o => o.SelectedType, @T("Media gallery type"))</div>
<div>@Html.DropDownListFor(o => o.SelectedType,
Model.AvailableTypes)</div>
<div>@Html.LabelFor(o => o.AutoPlay, @T("Auto play"))</div>
<div>@Html.CheckBoxFor(o => o.AutoPlay)</div>
}
</fieldset>
My problem is now, I cannot find or edit the widget with double used name. I would love to replace it to another name. But I do not know where to do this.
Please advice.
