Question

I have a compoonent inside flex4.5 in 3 columns

When I add some elements, soemtimes these one of these elements just got invisible:
when I resize the browser, it appears again.

There is no rule: it happens randomly and element is always avaible: I tried with referesh, update but this do not help.

ANy idea on why this happens and how to solve that bug ?

                <mx:DataGrid id="rowcolordatagrid1" left="10" right="10" top="49" variableRowHeight="true" 
                                         bottom="58" borderColor="#CCCCCC" color="#5A5A5A" dataProvider="{questions_dp}" symbolColor="#CCCCCC">
                <mx:columns>                        
                    <mx:DataGridColumn dataField="data" headerText="{xml.questions}" itemRenderer="QuestionRenderer" sortable="false"/>
                    <mx:DataGridColumn width="150" headerText="{xml.action}" itemRenderer="ActionRenderer" sortable="false"/>
                    <mx:DataGridColumn dataField="priority" headerText="{xml.priority}" itemRenderer="PriorityRenderer" width="100"  />
                </mx:columns>
            </mx:DataGrid>

of course I tried questions_dp.refresh();

But when I resize or minimize my browsers, these blank lines appear again !
These lines happens sometimes : I would say 20% of chance some rows are invisible.

I think the reason is because your item render.

remove ‘QuestionRenderer’ and try again.

if it is OK for the first column, then check all your render class:
Did you forgot to call super.method(..) with in every override metod in you render class?
