Re: using template directives with anchor tags

Hi,

I just started working with Barracuda, so please feel warned that the 
following hint may not be the most elegant or "right" solution for your 
question.
I run into the same problem last week. After a day try-and-error I figured 
out, that you can nest directives. My experiences with BLink, BTable and 
setName() had not been successfull. Maybe I tried it the wrong way. 

Here comes my (working) solution. (My html is generated. I removed lots of 
formating tags "by hand" for this posting ... maybe I removed to much ...)

<TABLE> 
  <TR class="Dir::Iterate_Start.MainScreenData 
Dir::Iterate_Next.MainScreenData"> 
    <TD><P><span 
class="Dir::Get_Data.MainScreenData.Project">primeProject</span></P></TD> 
    <TD><P><A HREF="../html/current.html" 
class="Dir::Get_Data.MainScreenData.DataSet"> 
           <span 
class="Dir::Get_Data.MainScreenData.CurrentDataSetName">Display 
Text</span></A></P></TD> 
  </TR> 
  <TR class="Dir::Iterate_Next.MainScreenData"> 
    <TD><P><span 
class="Dir::Get_Data.MainScreenData.Project">otherProject</span></P></TD> 
    <TD><P><A HREF="../html/currentshare.html" 
class="Dir::Get_Data.MainScreenData.DataSet"> 
            <span class="Dir::Get_Data.MainScreenData.CurrentDataSetName">Next 
Text</span></A></P></TD> 
  </TR> 
  <TR class="Dir::Iterate_End.MainScreenData Dir::Discard"> 
    <TD><P>..</P></TD> 
    <TD><P>..</P></TD> 
  </TR> 
</TABLE>

And here the corresponding java code snipplet:

	public Object getItem(String key) { 
		ViewContext vc = getViewContext(); 
		if (key.equals("Project")){ 
		 	return currentDataSetData.getProject(); 
		} else if (key.equals("DataSet")) { 
			String dataSetName = currentDataSetData.getDataSet(); 
			BAction link = new BAction(new GetDataSetData()); 
			//link.setName(dataSetName); 
			try { 				
link.setParam("project",URLEncoder.encode(currentDataSetData.getProject(),"ISO-8859-1")); 
link.setParam("dataSet",  URLEncoder.encode(currentDataSetData.getDataSet(),  
"ISO-8859-1")); 
				} catch (UnsupportedEncodingException e) { 
				logger.error("Unable to URLEncode (ISO-8859-1) in MainScreen.java"); 
				e.printStackTrace(); // ToDo: remove this line after testing method 
			} 
			return link; 
		} else if (key.equals("CurrentDataSetName")) { 
			return currentDataSetData.getDataSet(); 
		} else { 
			return super.getItem(key); 
		} 
	} 

Maybe this hint is useful for you.

Regards
Martin
