Hello Everyone,

I recently wrote a SAP UI5 (Master / Detail Theme) application, which is now used in the company. Now I have received a bug report which says that after about half an hour (of inactivity) fragments (dialogs), which are called by the detail controller, can't be loaded anymore. The following error is thrown:

sap-ui-core.js:217 Uncaught Error: resource .../.../.../view/AddRecordDialog.fragment.xml could not be loaded from ./view/AddRecordDialog.fragment.xml. Check for 'file not found' or parse errors. Reason: Error: Invalid XML: <!DOCTYPE html PUBLIC "-//WAPFORUM//DTD XHTML Mobile 1.0//EN" "http://www.wapforum.org/DTD/xhtml-mobile10.dtd">
<html

        </head>
        <body style="background-color:#FFFFFF">

            </p>
        </body>

    at Object.X.loadTemplate (library-preload.js:819)
    at constructor.init (library-preload.js:362)

The strange thing about this error is that it only appears in fragments called by the detail controller. Fragments called from the master side works fine.

I guess the detail page timed out somehow. Is there a way to programmatically re-authenticate to the server side?

Thank you for every answer. I hope you can help me with my problem.

Cheers Jannik

Hi Jannik,

An app should timeout completely and not the individual views ( Master/Detail).

Does the same scenario happens if you have loaded a fragment from Detail Controller and then wait for another half hour and try to reload it.

I think the way your fragments are loaded in the view is making the difference.

Can you check what is the difference in the loading of fragments in both Views ?

If possible can you share your code for Controllers to identify the root cause.

Thanks,
