how to add components in table

rang3r

Hi All,<br />
I was start learning BIRT. And i have a problem. I create a table (this OK, in Eclipse IDE i may see my table).<br />
But i cant add simple label in cell on my table.<br />
this is stackTrace:<br />
<pre class='_prettyXprint _lang-auto _linenums:0'>
org.eclipse.birt.report.model.api.command.ContentException: Element "Label("MyLAbel")" is not allowed to be added into the (content) of "Table("myTable").Footer[0].Cells[0]", for it is already in the design tree.

Please help me!<br />
THank you!

Hi rang3r,

You get this error with the line:

model.getCell(model.getRowCount()-1,model.getColumnCount()-1).add("elem",label);

commented out like in the code above? Or when you try to use that line? If it's when you try to use that line, try commenting out the line:

design.getBody().add(label);

Then you won't be attempting to have the same label with the same name in the design twice. That's just my first guess.
