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

[tstronge]

I'm making some progress with an "anonymous" TableDecorator containing the
following startRow() implementation:



>   public String startRow(){
>     String returnAssignmentsStr = "";
> 
>     if (getCurrentRowObject()!=null){
>       String[] returnValueAssignmentPairs = (String[])
> getPageContext().getAttribute("returnValueAssignmentPairs");
>       
>       for (int i=0; i<returnValueAssignmentPairs.length; i++){
>         String parentObjFieldName =
> returnValueAssignmentPairs[i].split("=")[0];
>         String listObjFieldName =
> returnValueAssignmentPairs[i].split("=")[1];
>         
>         String fieldValue = evaluate(listObjFieldName).toString();
>         
>         returnAssignmentsStr =  returnAssignmentsStr + parentObjFieldName
> + "=" + fieldValue;
>         if (i<returnValueAssignmentPairs.length-1){
>           returnAssignmentsStr += ";";
>         }
>       }
>       
>       this.getPageContext().setAttribute("returnAssignmentsStr",
> returnAssignmentsStr);
>     }    
>     
>     return null;
>   }

I just can't seem to get the "returnAssignmentsStr" attribute when I need it
in my JSP...



>                   <display:column media="html" 
>                                 title="....blah, blah
> 
>                       &lt;a href="#" 
>                          class="DATA-LINK" 
>                         
> onclick="javascript:populate_parent('${returnAssignmentsStr}')"&gt;
>                          <c:out value="${tableRow[columnName]}"/>
>                        
>                 </display:column>

It's probably something stupid & this hour of a Friday evening it's time to
give up til Monday!
