URL from DataItemHandle ?

Hi! I'm trying to display HTML links contained in a DB, but once the report is generated, the href tags are displayed as text and not as actual links...

Is there a particular item to set on the DataItemHandle so that HTML links can be displayed as links? It's in a dynamic report, here's the dataItem creation bit:

CellHandle cellDetail = (CellHandle) detailRowHandle.getCells().get(newAttributeIndex);
DataItemHandle data = elementFactory.newDataItem(name);
data.setResultSetColumn(computedColumn.getName());
cellDetail.getContent().add(data);

I found this: http://www.birt-exchange.org/org/forum/index.php/topic/15569-embed-a-html-link-in-a-report/page__s__6cfe1c8f812c2295a49171933e4069f2 Could/Should I somehow incorporate the format in the setExpression of the computed column or something?

Thanks!

Hi akk2, 
 
a data element has a property "action" which you can set. The corresponding structure in the XML of your generated report design would be: 
[code=auto:0] 
<data id="data_23"> 
<list-property name="action"> 
<structure> 
<property name="linkType">hyperlink</property> 
<property name="toolTip">Visit google</property> 
<expression name="uri" type="constant"><a class='bbc_url' href='http://www.google.com</expression>'>http://www.google.com</expression></a> 
<property name="targetWindow">_blank</property> 
</structure> 
</list-property> 
</data> 
[code=auto:0] 
 
I haven't tried this code, but you would want something along the lines of : 
[code=auto:0] 
DataItemHandle data = elementFactory.newDataItem( "data_23"); 
 
ActionHandle action = data.getActionHandle(); 
 
action.setLinkType(DesignChoiceConstants.ACTION_LINK_TYPE_HYPERLINK); 
action.setTargetWindow("_blank"); 
action.setToolTip("Visit Google"); 
Expression googleUrl = new Expression("<a class='bbc_url' href='http://www.google.com'>http://www.google.com"</a>, "constant"); 
action.setExpressionProperty("uri", googleUrl); 
[code=auto:0] 
 
Hope that helps, 
Cedric

Thanks cypherdj it helped a ton! ^_^

Btw, if some others have to do something similar, I ended up creating two ResultSets and two computed columns for each URL, one for the URL, and the second for the text of the link. The dataItemHandle displays the text, and has the action & Expression open the URL from the second computedColumn value using a javascript expression instead of a constant.

Also in my case the data was created dynamically and data.getActionHandle() returned a null, so I had to use the following:

Action action = StructureFactory.createAction();
ActionHandle actionHandle = data.setAction(action);
actionHandle.setLinkType(DesignChoiceConstants.ACTION_LINK_TYPE_HYPERLINK);
actionHandle.setTargetWindow("_blank");
// action.setToolTip("****");
Expression expressionUrl = new Expression("row[\""+computedColumnUrl.getName()+"\"]", ExpressionType.JAVASCRIPT);
action.setExpressionProperty("uri", expressionUrl);

There's probably a better and more elegant solution to do it, but the above seems to work well. Thanks for your help!
