Parameters not being set on Action in Struts 2

[Tarek Nabil <Ta...@dubaiworld.ae>]

Hi,

I'm experimenting with Struts 2, and I'm facing a problem with request
parameters being populated on the Action. I checked out the source to
make sure that the behavior I expect is the correct one, and judging by
the source, it is, but it's not happening.


I have an action that has a method

public void setType(Integer type) {
	// some code
}

I declared the action in Struts.xml as follows

        <action
	    name="dod1"
	    method="setup"
	    class="somePackageName.someClassName">
	    <result name="page">/jsp/someFolder/someJSP.jsp</result>
            <result name="input" type="chain">dod1!setup</result>
        </action>

In the setup method, I put the following line

	    logger.debug(getContext().getParameters());

In the URL, I call the following

http://server/application/namespace/dod1!setup.action?type=1

The result is that the parameters map is logged as {} and in my method
when I attempt to access the type field, I find it to be null!

Could someone please point me to what could be wrong?

Thanks,
Tarek Nabil

Re: Parameters not being set on Action in Struts 2

[Ted Husted <hu...@apache.org>]

First, simplify the problem. Right now, the code seems to be calling
an alternative method, setup. What happens if you try the same thing
with the default execute method?

If your application is based on the blank application, it may turned
the "!" syntax off, since it can conflict with using wildcards. To use
the Check the struts.properties file for the line
"struts.enable.DynamicMethodInvocation", and set it to true.

We're working on some new code for Struts 2 that will extend the "!"
syntax so that it can happily coexist with wildcards.
