Freemarker errorMessages not working.

[sergi]

Hi,

I'm using Freemarker as the view technology, but I have problems while trying to show the errors. I have a simple form like this one:



<#import "spring.ftl" as spring>

<form action="" method="post">
<table>
<tr>
<td colspan=2>
<#list spring.status.errorMessages as error> <b>${error}</b> <br> </#list>

</td>
</tr>
<tr>
<td>
<@spring.messageText "login.username", "username"/>
</td>
<td>
<@spring.formInput "login.username", "","text"/>
</td>
</tr>
<tr>
<td>
<@spring.messageText "login.password","password"/>
</td>
<td>
<@spring.formInput "login.password", "", "password"/>
</td>
</tr>
<tr>
<td></td>
<td><input type="submit" value="Login"></td>
</tr>
</table>
</form>


And in my xml file:



<bean id="viewResolver"
class="org.springframework.web.servlet.view.freemarker.Fr eeMarkerViewResolver">
<property name="cache" value="true" />
<property name="prefix" value="" />
<property name="suffix" value=".ftl" />
<property name="exposeSpringMacroHelpers" value="true" />
<property name="exposeRequestAttributes" value="true" />
<property name="exposeSessionAttributes" value="true" />
</bean>


But I get the following error:


Expression spring.status is undefined on line 14, column 24 in login.ftl.
The problematic instruction: ---------- ==> list spring.status.errorMessages as error [on line 14, column 17 in login.ftl] ----------
Java backtrace for programmers: ---------- freemarker.core.InvalidReferenceException: Expression spring.status is undefined on line 14, column 24 in login.ftl. at freemarker.core.TemplateObject.assertNonNull(Templ ateObject.java:124) at freemarker.core.TemplateObject.invalidTypeExceptio n(TemplateObject.java:134) at
.....


I don't know why, 'cause if I remove the showing-error line, everything works. Any ideas? Has anyone had the same problem before?

Thanks.

You should define spring.ftl at the beginning of your freemarker template. Check below:



<#import "/spring.ftl" as spring />
..
..

<#if spring.status.error>
....
</#if>

I hate to resurrect a long-dead thread, but I'm having *exactly* this problem and I *SWEAR* I'm importing spring.ftl already. Does anyone have any other ideas for what the problem is?



<#import "/spring.ftl" as spring>
...

<#if spring.status.error>
<div class="errors">
There were problems with the data you entered:
<ul>
<#list spring.status.errorMessages as error>
<li>${error?html}</li>
</#list>
</ul>
</div>
<#else>
<div class="errors">
There are no errors.
</div>
</#if>


results in:


Expression spring.status is undefined on line 35, column 6 in whatever_file.ftl.
The problematic instruction:
----------
==> if-else [on line 35, column 1 in whatever_file.ftl]
----------

at freemarker.core.TemplateObject.invalidTypeExceptio n(TemplateObject.java:134)

Can someone PLEASE tell me what the heck I'm doing wrong?! I'm so frustrated now! I've been trying to get this resolved for hours now!

Hey...I'm facing the same issue and have been trying to get this solved for around a week now :(...SOS !

I managed to solve this sorta after looking at the code in spring.ftl. I put this code into a separate file errors.ftl and I include it in any template that needs to show these errors:


<#import "/spring.ftl" as spring />
<@spring.bind "command" />
<#if spring.status.error>
<div class="errors">
There were problems with the data you entered:
<ul>
<#list spring.status.errorMessages as error>
<li>${error?html}</li>
</#list>
</ul>
</div>
</#if>

Notice the @spring.bind thing? That's what made the whole thing work I think.

[sabbath-shadow]

the meaning thing is that in <@spring.bind "command" /> there should be a string, not a command object itself.
