[flexcoders] Re: Casual Channel.Call.Failed while using remoteObject

[gene_belor]

My problem was caused by the compression filter used in web.xml. As
the result, IE6 could not properly uncompress data to pass it to Flash
Player.

Hi,

Did you figure out the Channel.Call.Failed problem?

I get it consistently for only one remote call to Java backend if my
swf is loaded from IE6. And the same call works fine in IE7 or Firefox.

Any suggestions on how to troubleshoot this problem in Flex or Java?

Thanks!

[flexcoders] Re: AdvancedDataGrid ItemRenderer

[gene_belor]

override updateDisplayList(..) function and set visibility there as
opposed to in set data(...).

[flexcoders] AdvancedDataGrid (DataGrid) Change cell editability at run time

[gene_belor]

Hi,

I think the way AdvancedDataGrid (DataGrid) allows cells to be
editable through AdvancedDataGridColumn (DataGridColumn)'s editable
property is restrictive because the property works on the whole column

I was wondering what is the best approach for dynamically changing
whether a cell is editable or not based on a selection in another cell
of the same row. 

For example the following grid:
1) "TYPE" column is a drop down
2) "VALUE" column is editable column
3) "TYPE" column options are "Keep" and "Change"
4) "Keep" option makes associated cell of "VALUE" column non editable
5) "Change" option makes associated cell of "VALUE" column editable
6) As user changes selected option in "TYPE" column, editability of
"VALUE" cells change

TYPE  VALUE
  --
KEEP  1 (non editable)
CHANGE2 (editable)  

Thanks!
