Error when launching reporting menu item from MES

Epicor ERP 10
1

We have a number of custom buttons in MES for launching forms, using C# code tied to the menu item ID. This is the first time I have added a menu item that is of the “report” style, and I am getting the following error:

Application Error

Exception caught in: Erp.Mfg.UIRpt.PCIDContectsReportEntry

Error Detail 
============
Message: Unable to cast object of type 'System.String' to type 'System.Collections.Hashtable'.
Program: Erp.Mfg.UIRpt.PCIDContectsReportEntry.dll
Method: OnFormLoaded

Client Stack Trace 
==================
   at Erp.Mfg.UI.Rpt.PCIDContectsReportEntry.ReportForm.OnFormLoaded()
   at Ice.Lib.Framework.EpiBaseForm.formLoaded()

The report still launches after clicking OK, but I am wondering if this has something to do with the parameters getting passed in on form load. I have searched through the trace and not sure where to go.

Can you post the code? I think you are on the right track in looking at how you are passing the parameters.

I’m not actively passing any parameters…but maybe I need to, or modify what is being passed by default?

I was able to reproduce the error. Try adding a blank launch form options and passing it in the call. Killed the error for me.

LaunchFormOptions lfo = new LaunchFormOptions();
ProcessCaller.LaunchForm(this.oTrans, “Erp.Mfg.UIRpt.PCIDContectsReportEntry”,lfo);

(insert your menuID)
(Sorry, this text did not want to get formatted)

Not sure exactly why, but something related to the launch form options being a hashtable. Maybe a blank string was being passed instead, not sure. Maybe someone else can shed some light on why this is happening.

Adam, thank you so much! I have set up LFO’s before but didn’t even think of that. Much appreciated.

No problem! Lucky (educated) guess on my part.
