I have a provider-hosted SharePoint app that I point to via a link in a promoted links list. Launch Behavior is set to "Dialog" and my app opens fine in the dialog window. My problem is that the title of the dialog is "Dialog". HTML generated:
<h1 title="Dialog" class="ms-dlgTitleText ms-accentText ms-dlg-heading" id="dialogTitleSpan" style="width: 718px;">Dialog</h1>
When writing custom code and opening pages with showModalDialog there is an option to set title, but in a standard promoted links list, I can't find any option to set the title of the dialog window(I supposed that it uses the showModalDialog somehow in the background)?
I can probably fix this with code, but I'm curious to know if this can be achieved through configuration in the promoted links list.
