In Fiori launchpad, the page title will display default value “Home”. When I click a given tile to enter an UI5 application, the page title is changed for example from “Home” to “My Tasks”.
Today I am dealing with an incident that once I have entered one application, the page title is not displayed correctly, see below error screenshot:
In order to fix this issue, I need to know exactly which line has changed the value of page title.
Since I don’t have any clue why page title becomes like this when I enter the erroneous application, so my thought is if I can test with an application where the page title works correctly, and if I can find out the line of code for title value assignment, then I can set breakpoint on that line and debug back with erroneous application.
Thanks to the power of Chrome development tool, I can finish trouble shooting in a quite efficient way.
First step, Identify which html tag holds the value of page title. Open Chrome development tool, click Elements tab and locate the tag “title”. Change its value and the change will refresh in browser immediately. This proves the fact that it is title tag which holds page title.
