AX 2012 - Workflow form open error

 

At one of our customers Workflow wasn't opening. Also error message wasn't so much explaining:

After a review of Event log, couldn't find any log about this error. Tried all suggested solutions at web, still no success:

-Incremental CIL

-Full CL

-XppIL klasörünü silip AOS restart

-Full compile ve Full CIL

-Client reinstall

At a blog says there isn't inner CLR catch at try/catch in WorkflowEditorHost form. Like blogger did I decided add include these red lines to form:

 

private void build()
{
    #Admin

        throw error("@SYS108268", '', sysInfoAction);
    }

    versionTable = element.args().record();

    //BP Deviation Documented
    select userInfo where userInfo.Id == curUserId();

            //AGC memre           
            throw error("@SYS327400");
        }
    }

}





public void run()
{
    //AGC memre
    #OCCRetryCount
    System.Exception ex;
    //AGC memre

    try
    {
        modelEditorControl.Load(workflowConfiguration, userSettings);
        workflowEditorPane.initializeActionPane();
        if (element.args().openMode() == OpenMode::View)
        {
            isReadOnly = true;
            modelEditorControl.set_IsReadOnly(true);
            modifyElementButtonGroup.caption("@SYS322934");
            modifyWorkflow.caption("@SYS322935");
            viewToolboxButton.visible(false);
        }
    }
    catch (Exception::CLRError)
    {
    //AGC memre
        ex = ClrInterop::getLastException();
        if (ex != null)
        {
            ex = ex.get_InnerException();
            if (ex != null)
            {
                error(ex.ToString());
            }
            else

        else
                error(AifUtil::getClrErrorMessage());
    //AGC memre
        throw error("@SYS327400");
    }

    super();
}
 

Then I could get a clear error message:

 

Looked inbound ports, reviewed Windows firewall, reviewed Ax32Serv.exe.config file, seem everything good. But client configuration tool still couldn't WCF refresh:

 

 

In spite of there is just one AOS at the computer, tried to write Instance Name:

 

Problem was solved:
