2012/9/11 G.Subramanian g...@7stl.com:
 Hi, i'hv created a custom tag in Strtus 2. where, from action iam passing a
 arrayList object in the value attribute when custom tag java is calling.
 please tell me how to take that arrayList object in my custom tag java file.
 give me some exmple code.

And how do you map that arrayList to html ? It's hard to understand
your problem without a code example.


Regards

 this is a correct question.

 my problem is that i have a form. the form is posted to an action. the
 action has getters/setters for the form fields. i then forward to
 form-success.jsp. on this page, i can use the struts taglibs to access
 the information posted. for example, s:property value=email/.
 however, if i have a custom tag, how do i access email from the
 ActionContext? for example, customTabLib:showEmail value=email/,
 doesn't work. the tag displays the value, email. i also tried a
 couple of things too that didn't work.

 customTagLib:showEmail value=#email/
 customTagLib:showEmail value=%{#email}/

 is there a class/interface that i can extend/implement in struts 2
 that would easily help me get the value of email from the
 ActionContext in my custom tag?

 thanks.

Hi Jake,

I have a custom table tag that needs Value Stack access, too.
Here's how I do it:

package...

import org.apache.struts2.views.jsp.TagUtils;
import org.apache.struts2.util.MakeIterator;

public class TableTag extends SimpleTagSupport
{
private String list;

public void doTag() throws JspException
{
ValueStack stack = TagUtils.getStack((PageContext)getJspContext());
Iterator iterator = MakeIterator.convert(stack.findValue(list));
while (iterator.hasNext())
{
...
}
}

public void setList(String list)
{
this.list = list;
}
}

Of course list is one of my custom tag's attributes and appropriately
defined in my TLD.

Cheers,
Bill
