Hi,
I have custom field type which is using AssetUrlSelector to select image. If i add this custom field to publishing pages document library along with PublishingHtml field and then open any page and try to edit it using "Edit page" option then after clicking in PublishingHtml and trying to insert image in it i have "From SharePoint" option disabled. If i remove my custom field or comment out lines in custom field code which adds AssetUrlSelector then this option becomes enabled. The presence of AssetUrlSelector some how alters status of this button. If i try to edit document properties via "Edit properties" menu then this option is enabled in both cases.
What can be a cause of this problem?
Best regards, Chernobrivets
