Hi all,
I was searching the nabble archive but still am not quite sure how FileUploads are supposed to work with 3.0 M1. I have a test implementation of my webapp that currently give me the error: Parameter callCount not defined!
When I do a normal DWR request that does not involve a file upload, it still works fine (as it was in DWR 2.0.3).
We are using Spring, so DWR is conifgured using this in one of the spring xml files:
<bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
<property name="mappings">
<props>
<prop key="/engine.js">dwrController</prop>
<prop key="/util.js">dwrController</prop>
<prop key="/interface.js">dwrController</prop>
<prop key="/call/**">dwrController</prop>
<prop key="/interface/**">dwrController</prop>
</props>
</property>
</bean>
<dwr:controller id="dwrController" debug="true" />
<dwr:configuration>
</dwr:configuration>
The Bean that exposes methods is this:
<bean id="AJAXController" class=" ... ">
...
<dwr:remote javascript="Mac">
<dwr:include method="checkIO"/>
<dwr:include method="checkImage"/>
</dwr:remote>
</bean>
On the client side, I call the checkImage function liek this:
//DWR
var creative = dwr.util.getValue(fieldId);
//YAHOO.log(creative);
Mac.checkImage(creative, c.width, c.height, c.size, fieldId,
{
callback: function(result)
{
alert("Image check: " + result);
},
timeout: 5000,
errorHandler: function(message)
{
alert("Oops: " + message);
}
});
I verified that the parameter creative really is resolved into the input element that I want to upload.
The method on the server that I am trying ot invoke is this:
public boolean checkImage(FileTransfer uploadImage, Integer width, Integer height, Float size, String creativeId ) throws IOException
{
log.debug("verifyImage()");
...
}
Basically it never get's invoked. once Mac.checkImage ()... is called I get the error wiht
'Failed to find parameter: callCount'
Any ideas?
Could it be that DWR needs to be configured a bit differently in 3.0, especially when it comes to Spring?
Thanx
Sven
