Make sure that, Is there any text fields or any labels are in the cells.
In tbl_get_cell_data() will capture the value of the cell only. if the cell value embed with any objects like textfield or label, it will return null.
You should specify the object name to get the value if so.
Thanks for the response. It turns out I can use the java_activate_method() for this . The getValueAt Java method returns an object and then I pass that as an input parameter to the toString Java method.
I am having a similar problem, I am not able to recognize the cell value in a table, and hence was using the java-activate_method ot getValueAt but even this doesnt work for me as you suggested to pass it to "toString" value....can you please let me know how exactly you resolved this issue, your help in this regard would be appreciated...
