Re: [displaytag-user] Using Link on Column to populate fields (plural!) in parent screen

[tstronge]

I've successfully gone with the TableDecorator solution as suggested by Ed -
it's more obvious/cleaner than using my taglib function solution from
yesterday.  

Code for reference:



>   public String getReturnValuesLink() {
>     String returnAssignmentsStr = "";
>     
>     String[] assignmentPairs = (String[])
> this.getPageContext().getAttribute("returnValueAssignmentPairs"); 
>     String linkField = (String)
> this.getPageContext().getRequest().getParameter("linkField"); 
>     
>     for (int i=0; i<assignmentPairs.length; i++){
>       String assignTo = assignmentPairs[i].split("=")[0];
>       String assignFrom = assignmentPairs[i].split("=")[1];
>       String fieldValue = evaluate(assignFrom).toString();
>       returnAssignmentsStr = returnAssignmentsStr + assignTo + "=" +
> fieldValue;
>       
>       if (i<assignmentPairs.length-1){
>         returnAssignmentsStr += ";";
>       }
>     }
> 
>     return "&lt;a href=\"#\" class=\"DATA-LINK\"
> onclick=\"javascript:populate_parent('" + returnAssignmentsStr +
> "')\"&gt;"
>     + evaluate(linkField).toString() + "&lt;/a&gt;";
> 
>   }
>
