Hi Rogelio, below the code i used to create my CellTable populated by
dataset of ValueProxy, received via request factory (onClickGetList
method). I can show data in the CellTable also the pager everything work
fine. The problem occur when i want to update a row via SelectionCell, it
take a long time before update and some time i get (remote connection lost)
or (Stack overflow; to increase the stack size, use the -Xss flag at
startup (java -Xss1M ...))
To be sure which part of code cause the problem, i put a message inside
getValue method and update method, i found out an several call to getValue
method and NO call to update method.
*PS:*
- *ValueProxy (ConceptProxy) that i received do not have TypeConcept, i
want to set it via SellectionCell That's why i return **"Unknown"** if
TypeConcept == Null in getValue method*
- *My GWT app based on Activities & Places and the code below is in a
view implementation that extend Composite class and implement the view
interface.*
