[0.8.2] Error Getting AjaxMethod Value

[protactinium]

Hey all,

I'm using a codebehind process for modifying the dataObject before saving, deleting and inserting.
For that I pass the record from the ProductsStore to the codebehind as a parameter.

I'm using also a Function (CheckData) to commit the Data Changes before the event

        var CheckData = function () {
            if (!#{FormPanel1}.getForm().isValid()) {
                
                return false;
            }
            #{FormPanel1}.getForm().updateRecord(#{ProductsStore}.getAt(0));
            #{ProductsStore}.commitChanges();
            return true;
        }

For testing, I'm using MessageBox to show the entity.

    protected void MenuItem7_Click(object sender, AjaxEventArgs e)
    {
        
        Ext.Msg.Alert("AjaxEvent", string.Format("Item - {0}", e.ExtraParams["ProductEntity"])).Show();
    }

<ext:ToolbarButton ID="BtnSave" runat="server" Icon="Disk" Text="Enregistrer">
    <AjaxEvents>
        <Click OnEvent="MenuItem7_Click" Before="CheckData()">
            <ExtraParams>
                <ext:Parameter Name="ProductEntity" Value="#{ProductsStore}.getRecordsValues()"
                    Mode="Raw" Encode="true" />
            </ExtraParams>
        </Click>
    </AjaxEvents>
    <ToolTips>
        <ext:ToolTip ID="ToolTip7" runat="server" Html="enregistrement." />
    </ToolTips>
</ext:ToolbarButton>

My problem is that I cannot get the updated data in the codebehind directly.
For example, if I change the ProductName in the formPanel, I cannot get this modified data only if I click another time the saveBtn

Here you are the scenario :
1) I change the product name YYYY to XXXX.
2) I click Save
3) The product name passed to the codebehind is YYYY
4) I click save again
5) The product name passed to the codebehind is now XXXX


So, what's wrong ?? I checked the ProductsStore.getRecordsValues with FireBug. It return the productName XXX during the first click.



Thanks again for you help.

Hi,

Before handler is called after params building. The reasone: to give ability to change params in the Before handler


Possible solutions:


1. Add click listener and call 'CheckData' in that listener. It is guarantee that record updating will be performed before AjaxEvent


or


2. Get data in the CheckData. Change CheckData signature

CheckData (el, type, action, extraParams)

And use the following code inside CheckData

extraParams.ProductEntity = ProductsStore.getRecordsValues();

As you can see option 1 requires less coding
