RE: [flexcoders] Re: saving data from datagrid

[Doodi, Hari - BLS CTR]

Thanks Matt,               I found where the problem is. I was following The Flex Book chapter 20 Flex integration with J2EE - where in the second parameter to Object.registerClass referred to constructor of ASObject class. This mislead me. When I specify the AS class name with qualifying path instead of constructor, everything started working fine. I don't know how to send this bug in the book to the authors. Can you send a comment to the authors on behalf of me??   Thanks!

(1)     When you pass dataprovider as a parameter to RemoteObject method, will this be treated as ASObject or an array of VOs ? (2)     When I pass dataprovider as is to as the argument to my Java Class method with java.util.List as input argument I found List is null. When I display the following info System.out.println("saveList.get(i) : "+saveList.get(i).getClass());  I got flashgateway.io.ASObject. So is there any way to convert ASObject to custome VO in POJO. When I tried to cast it to custom VO I got an error occurred during service invocation.   Thanks!

I did check the NetworkMonitor and found that array has values as shown below. In the example RestaurantFinder, he is getting individual values from the textinput controls and assigning them to VO attributes. My case is, I don't have any textinput controls. What I have on my screen is a editable datagrid. And I don't want to get values from each cell and assign them to vo( if there is no other way then I have to do this).   Come on, there are some excellent Flex gurus out there Did any one achieved saving data from editable datagrid on to database? I am desperate to solve this ASAP. I will be very thankful if some one post code for this.   Also how to declare, in flex, an array of type employeeVO? Something like this ....  var employeeVOArray:EmployeeVO = new Array( );   I got compilation error saying found Array where expecting EmployeeVO...   Please help me out..   Method: gov.bls.ppi.janus.rsgp.manageschedules.controllers.MngScheduleController.saveSchedAdj Parameter 1: name : param1 type : object value[array] : length[Number] : 5 [0][object] : adj_amt_terms_desc[String] : 15.0 10 Days/Net 60 Days 8 adj_category[String] : Net Price Conversion Factor - Surcharge adj_factor[String] : 1.2000 adj_month[null] : null adj_num[Number] : 1 adj_order_applied[String] : 10 adj_reporter_applied_flag[String] : Y adj_seas_flag[String] : N adj_sign[String] : Additive adj_status[String] : Y adj_type[String] : Seasonal irm[String] : 200404 item_sid[Number] : 1.16896E+006 row_change_flag[null] : null update_date_time[null] : null   [1][object] : adj_amt_terms_desc[String] : 15.0 10 Days/Net 60 Days Test 2 adj_category[String] : Net Price Conversion Factor - Discount adj_factor[String] : .1000 adj_month[null] : null adj_num[Number] : 2 adj_order_applied[String] : 1 adj_reporter_applied_flag[String] : Y adj_seas_flag[String] : N adj_sign[String] : Multiplicative adj_status[String] : N adj_type[String] : Seasonal irm[String] : 200404 item_sid[Number] : 1.16896E+006 row_change_flag[null] : null update_date_time[null] : null   [2][object] : adj_amt_terms_desc[String] : 15.0 10 Days/Net 60 Days Changed adj_category[String] : Discount adj_factor[String] : .1000 adj_month[null] : null adj_num[Number] : 3 adj_order_applied[String] : 10 adj_reporter_applied_flag[String] : Y adj_seas_flag[String] : N adj_sign[String] : Subtractive adj_status[String] : Y adj_type[String] : Seasonal irm[String] : 200404 item_sid[Number] : 1.16896E+006 row_change_flag[null] : null update_date_time[null] : null   [3][object] : adj_amt_terms_desc[String] : Values New and Modified adj_category[String] : Surcharge adj_factor[String] : .3000 adj_month[null] : null adj_num[Number] : 4 adj_order_applied[String] : 10 adj_reporter_applied_flag[String] : Y adj_seas_flag[String] : N adj_sign[String] : Multiplicative adj_status[String] : Y adj_type[String] : Seasonal irm[String] : 200404 item_sid[Number] : 1.16896E+006 row_change_flag[null] : null update_date_time[null] : null   [4][object] : adj_amt_terms_desc[String] : Values/Term 200411 adj_category[String] : Unit Conversion Factor adj_factor[String] : .3000 adj_month[null] : null adj_num[Number] : 5 adj_order_applied[String] : 10 adj_reporter_applied_flag[String] : N adj_seas_flag[String] : N adj_sign[String] : Multiplicative adj_status[String] : Y adj_type[String] : Seasonal irm[String] : 200404 item_sid[Number] : 1.16896E+006 row_change_flag[null] : null update_date_time[null] : null       Thanks!
