NullPointer exception when using AEnv.zoom wiht Idempiere (same code works on Adempiere 3.6.1)

[Pedro Rozo]

Hi everyone

I am trying to use the zoom functionality to open a Material Receipt document at the end of a process with Idempiere, I already have done it with  Adempiere without any issues, but with idempiere I have spent a couple of hours and it doesn´t work .. I got a null pointer exception all the time, is there any change in the API ?  anythng wrong with my code, this is the source code:

public static boolean openWindow2(Integer windowId, String table, Integer record){

 String whereString = " "+table+"_ID= "+record+" "; 

 MQuery query = new MQuery(table); 

 query.addRestriction(whereString); 

 int AD_Window_ID = windowId; 

 AEnv.zoom(AD_Window_ID, query);

 return true; 

}//openWindow2

I am using a valid window_id  from the AD ( similar to adempiere) 

windowId  = 184  //Material receipit window id

table= m_inout   // table name

record= 1000006  // existent material receipt document

I am just got this exception, any suggestions:

The difference is idempiere process is running as background thread, off the UI thread. To perform any UI operations you need to use the AEnv.executeAsyncDesktopTask(Runnable) api.

Thanks hengsin,  it is working now, here a simple example for other people looking about it:

public static boolean openWindow(Integer windowId, String table, Integer record){

OpenWindow ow = new OpenWindow();

ow.windowId = windowId;

ow.table = table;

ow.record = record;

AEnv.executeAsyncDesktopTask(ow);

 return true; 

}//openWindow

public class OpenWindow implements Runnable {

public Integer windowId;

public String table;

public Integer record; 

@Override

public void run() {

String whereString = " "+table+"_ID= "+record+" ";

 MQuery query = new MQuery(table); 

  query.addRestriction(whereString);    // restriction was removed

  String tabla = query.getZoomTableName();
