Putting values from datasource into attributes

[mdk]

Hi,

 

I have some problem with designing a jrxml file. I have to put values from datasource into attributes of ReportElement. For example in this way:

<field name="X" class="java.lang.Integer"/>

<field name="Y" class="java.lang.Integer"/>

 ...

<reportElement  x="$F{X}" y="$F{Y}" width="100" height="20"/>

but it generates error.

 

Anyone have some idea how to achive this?
