When click the screen on the Action button droup- down list of Refresh ,the error message is display.
Then in the activity ,the next step of Page-Set-Messages i used the following methods,but none of them solved my problem,and i want to know what the reason was
Thank you very much for taking the time to answer my question. I read your link, but i was going to display message at pre-activity instead of post-activity. and at post-activity the error mesaage can diaplay.
1) Refreshing the error section or harness after the screen entry. The error should appears with human interaction.
2) Configure your harness to use a Custom Error Section, after put the custom error section on the bottom of your harness (after the content!). The errors should appears on screen entry without human interaction.
If you pass on theses steps we may discuss futher solutions.
