Displaying Error Messages_Just View this

[Rajesh Babu，修改在14 年前。]

Errors messages displayed previously are shown on next page load (or) by clicking on back button.

below is my code to display the error messages:


<tr><td colspan="2"><b><form:errors path="unitName" cssStyle="color:red" /></b></td></tr>
<tr><td colspan="2"><b><form:errors path="firstName" cssStyle="color:red"/></b></td></tr>
<tr><td colspan="2"><b><form:errors path="lastName" cssStyle="color:red" /></b></td></tr>


anybody have any solutions or suggestions regarding this?

Hi Rajesh:
There's a taglib for this in Liferay.
we use it this way:

<liferay-ui:error exception="<%= EntryTitleException.class %>" message="please-enter-a-valid-title" />

Isn't it valid for you?

How do you know that you should display an error message? Is the validation is at server side or at client side?
