Hi friends,

I am trying to call my extension method in post event handler, but i am getting error like

"ClassDoesNotContainMethod: Table 'LedgerJournalTable' does not contain a definition for method 'getDebitBalance' and no extension method 'getDebitBalance' accepting a first argument of type 'LedgerJournalTable' is found on any extension class".

My extension class is

public static class LedgerJournalTable_Extension1
{
public static real getCreditbalance(LedgerJournalTable _LedgerJournalTable)
{
LedgerJournalTable ledgerJour;

select * from ledgerJour
where ledgerJour.JournalNum == _LedgerJournalTable.JournalNum;

return ledgerJour.JournalTotalCredit;

}

and my post init method is like,

[PostHandlerFor(formStr(LedgerJournalTable), formMethodStr(LedgerJournalTable, init))]
public static void LedgerJournalTable_Post_init(XppPrePostArgs args)
{
LedgerJournalTable ledgerJ;
LedgerJournalTable ledgerJournalTable = args.getThis() as LedgerJournalTable ;

ledgerJournalTable.getCreditbalance(ledgerJ);
}

Please suggest an solution for this error , how an call extension from method inside post init method .

Thanks & regards,

Sounds like models are not referred well. Please make sure your Suite is getting reference of those suites which are having these methods. it also happens sometimes that the method itself contains something which further refers to another suite. in such case that 3rd or 4th level of package also need to be referenced. this can be done by updating model parameters.

Thank you for posting these images. My suspicion is still as described previously.

do you want to have a look at to which suite the method getCredit.. belongs?

Also please note the Model/Suite for LedgerJournalTable.

Then finally make sure if those suits that you have found above are referenced in your extension model.

Hi Padma

I'm not sure which platform you're on but if you're on the 7.1 then what I see is wrong.

If you creating an extension of a class/table/form then you need to use ExtensionOf attribute and make it final instead of static so you are not confined to creating static methods only. And if you are creating a extension then your class name has to end with "Extension" rather than "Extension1" regardless of the platform you are on.

Please refer to this on how to create an extension class: docs.microsoft.com/.../class-extensions

From the screenshots that you have put up, I can see that you're creating a post handler of the form init method. Why not use the OnIntialized event? Nonetheless, your post-handler looks wrong as well. Your method is static, you won't be able to call it using a dot operator anyway.

So a few pointer:

1. If you're on 7.1 or above, this is how your extension class should look like:

[ExtensionOf(tableStr(LedgerJournalTable))] public final class LedgerJournalTable_Extension

2. Change your method from static to non-static and you don't need send in the record

public real getCreditbalance() { LedgerJournalTable ledgerJour; select * from ledgerJour where ledgerJour.JournalNum == this.JournalNum; return ledgerJour.JournalTotalCredit; }

3. Post-handler:

[PostHandlerFor(formStr(LedgerJournalTable), formMethodStr(LedgerJournalTable, init))] public static void LedgerJournalTable_Post_init(XppPrePostArgs args) { //args.getThis() will return you an instance of the formRun FormRun formRun = args.getThis(); //From this you need get your LedgerJournalTable cursor LedgerJournalTable ledgerJournalTable = formRun.dataSource(formdatasourcestr(LedgerJournalTable, LedgerJournalTable)).cursor() as LedgerJournalTable; //call your method real creditBalance = ledgerJournalTable.getCreditbalance(); }

Try this out

Let me know how it goes.
