setSerializableColumns() not working properly

Suite and Optimus Suite 5
#1

when I use setSerializableColumns() with boolean arguments, it disables the sendData() function of data processor. Here is my code(I know that there are 3 columns in the grid):

mainGrid.setSerializableColumns(true,true,false);
mainDataProcessor.sendData();

If I use string arguments, either setSerializableColumns(“true,true,false”), or setSerializableColumns(“true”,“true”,“false”), it has no effect - I can change the third column and save it to the database.

Any help is appreciated!

setSerializableColumns() method has only one parameter - string with true/false values with comma delimiter. So valid version of using setSerializableColumns() method is following:
etSerializableColumns(“true,true,false”)
