Sometimes the move page wizard fails ( usually when we change the page name and URL while staying in the same part of containment tree.)
There is a spinner for a while, then there is a dialog that says "failed to load".
This is an intermittent problem, many times it works fine.
I've looked in the logs when the error occurs and the only ERROR message I can see is the following
GET /content/versionhistory.thumb.48.48.png HTTP /1.1 ] org.apache.jsp.libs.cq.Page.thumb_png_jsp resource has no content . path=/content/versionhistory.thumb.48.48.png referrer is null
Does this mean anything ?
There are some known issue reported to our engineering wherein moving the page in the same folder does not work in touch UI [next button is inactive].
Engineering team has fixed the issue in 6.5.4(CQ-4282307 | Page Move and Rename not working in Touch UI for a large set of content) via internal JIRA IDs CQ-4282943, CQ-4282307.
As a workaround, you can increase the size property of /libs/wcm/core/content/sites/movepagewizard/destination/field from 40 to 2000 and test this in a lower environment.
