The data provider for the grid is "masters" an ArrayCollection. The
form uses "master" which is an Object. I had to include the
Number(txtMasterRate.text) in the Binding or I get the type coercion
error when trying to save back to the database. It almost works - when
I make an entry in the form, the grid is updated. But trying to enter a
decimal causes weird behavior - it backspaces and clears the previous
entry. (No - it's not my keyboard) Is there another approach to use?
The datagrid looks like this:
<mx:DataGrid id="dgMasterStatus" editable="true"
dataProvider="{masters}" width="457" change="mastersChange()"
valueCommit="mastersChange()">
<mx:columns>
<mx:DataGridColumn headerText="Rate" width="120" dataField="masterRate"
>
</mx:DataGridColumn>
</mx:columns>
</mx:DataGrid>
======================================
Then the form looks like this:
<mx:Form width="264" >
<mx:FormItem label="Rate">
<mx:TextInput id="txtMasterRate" text="{master.groupRate}" >
</mx:TextInput>
</mx:FormItem>
============================
And the Binding looks like this:
<mx:Binding source="Number(txtMasterRate.text)"
destination="revmaxmaster.masterRate" />
