argument type mismatch - trying to replicate upload task

[Matt Raible <ma...@yahoo.com>]

After banging my head against the wall for a few hours, I'm hoping someone on
this list has an idea.  I keep getting the following error:

java.lang.IllegalArgumentException: argument type mismatch
	at java.lang.reflect.Method.invoke(Native Method)
	at
org.apache.commons.beanutils.PropertyUtils.setSimpleProperty(PropertyUtils.java:1566)
	at
org.apache.commons.beanutils.PropertyUtils.setNestedProperty(PropertyUtils.java:1460)
	at
org.apache.commons.beanutils.PropertyUtils.setProperty(PropertyUtils.java:1490)
	at org.apache.commons.beanutils.BeanUtils.populate(BeanUtils.java:567)


I have getters/setters for all the elements in my HTML form below - and I never
even get to my action class to debug it.  I've basically copied the UploadForm
example and added asset, description, and mediaType as Strings.  Then removed
filePath (hardcoding for now), and viewFile fields.  

<form method="POST" action="/onpoint/do/saveObject" id="assetForm"
name="assetForm">
   <input type="text" name="asset" size="30" value="">
   <textarea name="description" cols="30" rows="5"></textarea>
   <select size="1" name="mediaType">
      <option value="video">Video</option>
      <option value="text">Text</option>
      <option value="audio">Audio</option>
   <input type="file" name="theFile" value="">
   <button value="Cancel" name="org.apache.struts.taglib.html.CANCEL"
type="submit">Cancel</button>
   <button onClick="" value="Save" id="action" name="action"
type="submit">Save</button>
</form>

This is effectively saying that your form bean's set method for some 
property doesn't match the value (most likely a string) given to it..

Can you post your form bean??
