Hi,
I am having problems with initializing my combo box cell renderer.
I have a application initialize method call which calls a few
httpservice to get data
function appInit()
{
clcrSSrv.send();
clStatSrv.send();
clTypeSrv.send();
initCellRenderer();
}
the method initCellRenderer()
private function initCellRenderer() : Void
{
var comboBoxValues = clTypeSrv.result.types.type;
ComboBoxCellRenderer.dataProvider = comboBoxValues;
}
where 'ComboBoxCellRenderer' is my cell renderer and is a Action
script class file.
in the createchildren method i have
function createChildren(Void) : Void
{
super.createChildren();
createClassObject( Label, "comboLabel", 1, { styleName:this,
owner:this } );
createClassObject( ComboBox, "combo", 2, { styleName:this,
owner:this, selectable:true } );
combo.addEventListener( "change", this );
combo.addEventListener( "enter", this );
combo.dataProvider = ComboBoxCellRenderer.dataProvider;
combo.setStyle( "backgroundColor", getStyle( "selectionColor" )
);
changeFlag = false;
size();
}
my datagrid
<mx:DataGrid id="rsClients"
dataProvider="{findClientSrv.result.clients.client}"
change="selectClient(rsClients.selectedIndex)" height="100%"
toolTip="Client List" borderStyle="none" editable="true">
<mx:columns>
<mx:Array>
<mx:DataGridColumn
columnName="clid" headerText="Client ID"
marginLeft="4" />
<mx:DataGridColumn
columnName="clName" headerText="Client Name"
marginLeft="4" />
<mx:DataGridColumn
columnName="clType" headerText="Client Type"
marginLeft="4" cellRenderer="{ComboBoxCellRenderer}" editable="false"/>
<mx:DataGridColumn
columnName="clCrStatus" headerText="Credit
Status" marginLeft="4"/>
<mx:DataGridColumn
columnName="clStatus" headerText="Client
Status" marginLeft="5" />
<mx:DataGridColumn
columnName="name" headerText="Name"
marginLeft="5"/>
<mx:DataGridColumn
columnName="city" headerText="City"
marginLeft="4"/>
<mx:DataGridColumn
columnName="state" headerText="State"
marginLeft="4"/>
<mx:DataGridColumn
columnName="zip" headerText="Zip"
marginLeft="5"/>
</mx:Array>
</mx:columns>
</mx:DataGrid>
Now this setup works fine some times.. sometimes the cellrenderer does
not have any data, even though it is the same(single static) query
and i can see the data coming back from the jsp. I am thinking that
the createchildren method if called before the jsp has returned data
so I changed my httpservie to have result="initCellRenderer()"
<mx:HTTPService id="clTypeSrv" url="clTypes.jsp"
result="initCellRenderer()" showBusyCursor="true" />
even this creates the combobox sometimes and not all times..
I tried debugging and see the dataprovider is undefined inside the
createchildren method.
And also I found the createchildren method was called a total of 12
times initially, even though there are no rows to be shown initially.
Can anyone tell me how to solve the missing data problem and also why
the cellrenderer is being initialized 12 times.
