[wely cery，修改在7 年前。]

hi

im creating liferay faces portlets.when my codes gets some exceptions i see that my portlet give some outputs on portlet by himself.
i wana give my own outputs to the screen when a error comes.
so how can i disable liferay faces error handling and set my own error outputs?

Can you post an error example screenshot so we can see exactly what you mean by "outputs on portlet by himself"?

Thanks.

thank your for your reply at first.

i have create a liferay faces portlet who bring the user information from database.if the code cannot find any data from user in database it
gives error on portlet.
i would like to define the error outputs like a pop up text or something else. so what i wana know is can i disable the exception handle from liferay faces and set my own output (like pop up screen or something like that) on my portlet.

Sorry, you didn't answered my previous question about posting here a screenshot to see what kind of error is showing in your portlet.

Thanks.
