[jira] Created: (WW-2367) Custom StrutsTypeConverter's convertToString not called

Custom StrutsTypeConverter's convertToString not called
-------------------------------------------------------

                 Key: WW-2367
                 URL: https://issues.apache.org/struts/browse/WW-2367
             Project: Struts 2
          Issue Type: Bug
    Affects Versions: 2.0.11
            Reporter: Bob Tiernay
            Assignee: Don Brown


It appears as though a class that is registered in xwork-conversion.properties that extends StrutsTypeConverter will never have it's convertToString method invoked as part of the normal ognl processing.  This is most evident in the case of a converter that is required in a <s:select> tag.  

An interesting thing to note is that XWorkConverter is being invoked rather than StrutsTypeConverter.  Also TextParseUtil.translateVariables appears to not be able to find the correct converter in this context.

A few other users have also noticed this issue and have commented on it here:

Musachy Barroso commented on WW-2367:
-------------------------------------

Can someone provide an example of their actual jsp, converter and object being converter? Does this problem only happens on nested object in the select tag? here is what I did to replicate it:

xwork-conversion.properties:
org.apache.struts2.showcase.ConverterObject=org.apache.struts2.showcase.MyConverter

TestConverterObject .java:
public class TestConverterObject {
    private String name;
    private String value;

    public TestConverterObject(String name, String value) {
        this.name = name;
        this.value = value;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getValue() {
        return value;
    }

    public void setValue(String value) {
        this.value = value;
    }
}

MyConverter .java:
public class MyConverter extends StrutsTypeConverter {
    @Override
    public Object convertFromString(Map context, String[] values, Class toClass) {
        return null;  //To change body of implemented methods use File | Settings | File Templates.
    }

    @Override
    public String convertToString(Map context, Object o) {
        ConverterObject obj = (ConverterObject) o;
        return obj.getName() + obj.getValue();  //To change body of implemented methods use File | Settings | File Templates.
    }
}

jsp:
<s:select list="objects" name="objects" />

The list was initialized with a new TestConverterObject("A", "B"); and the generated html was:
<select name="objects" id="objects">
    <option value="org.apache.struts2.showcase.ConverterObject@1a64562" selected="selected">AB</option>
</select>

so the converter was indeed called

David Connard commented on WW-2367:
-----------------------------------

Re: "Don Brown and has indicated this was fixed in some later version" - sorry, but I don't think this is the case.

I have run into this issue on Struts 2.0.11, and have just spend half a day upgrading to Struts 2.1.2 in the hope that it might be fixed there.... with no luck.

Yes, I ran into the issue in particular with a <s:select> tag.  It appears that the toString() method of my DAO objects is being called instead of the convertToString() method of my StrutsTypeConvertor.  If however I put the "current" DAO object into an <s:textfield>, I do go via the appropriate convertToString() method.

Any idea when we can expect a fix...?  This is an annoying issue - meaning we have to manually specify how to convert each set of <s:select> list data.

---------------------------------

convertToString is also not called for Text-Tag <s:text>. convertFromString is working as expected.
