Hello,

i am using the html hidden tag as follows <html:hidden name="model" 
property="actualAddress.primaryKeyString"/>.

The bean model is available and has the function
public Address getActualAddress();

and Address has the function
public String getPrimaryKeyString();

If the getter method of the bean model returns null (getActualAddress()) then we 
receive the following error message.

java.lang.IllegalArgumentException: Null property value for 'actualAddress'

In my opinion the html:hidden field should render null value, like a call without 
dotted path and null value.

What is your opinion ?

Should we catch the exception in RequestUtils ? or in each Tag ?

I can fix it if you will tell me how i should do it.


Thanks 

Markus
