Hi all.
I'm in the middle of a custom widget. And I'm trying to pass an
Integer[][] from java to javascript using the LCA class.
I have managed to pass a String, an int and Integer[].
But what I really need is to pass an Integer [][].
I'm using the same method for the several types that I managed to pass
in the LCA class. It is like this:
writer.set(ChartLCA.PROP_ADDRESS, ChartLCA.JS_PROP_ADDRESS,
Object)c.getInt());
the getInt() returns the supposed Integer[][].
Any ideas? Anyone needs more information?
Thank you all for the time.

Bruno,
the JSWriter methods currently only handle one-dimensional arrays. You
would have to construct the two-dimensional array by yourself. The code
snippet below shows how this would look like.
static void set( JSWriter writer,
String functionName,
Integer[][] array )
throws IOException
{
StringBuffer buffer = new StringBuffer();
buffer.append( "[" );
for( int i = 0; i < array.length; i++ ) {
buffer.append( "[" );
for( int k = 0; k < array[ i ].length; k++ ) {
Integer value = array[ i ][ k ];
buffer.append( value );
if( k < array[ i ].length - 1 ) {
buffer.append( "," );
}
}
buffer.append( "]" );
if( i < array.length - 1 ) {
buffer.append( "," );
}
}
buffer.append( "]" );
// wrap in JSVar to prevent JSWriter from quoting the string
Object[] args = new Object[] { new JSVar( buffer.toString() ) };
writer.call( functionName, args );
}
Please note that you still would have to determine if the integer array
has changed and thus writing the JavaScript code is necessary at all.
