problem with getting an element properties in another element

Migrateduser

<p>Hi I have a table element and text element in my birt template. I am trying to set the tables display property to 'none' in the textElements expression builder in the following way</p>
<pre class="_prettyXprint _lang-">
reportContext.getDesignHandle().getElementByID(927).getStyle()
</pre>
<p>i am able to get TableHandle object but when i call getStyle() on it it returns null. so how can i set the tables display property to none out side the table element?</p>
