Using edit method on form from table extension methods

(0) ShareShare
ReportReport
Posted on by Community Member

I created a new extension from table BrazilParameters and created a new method of type edit:

public edit Name profitCenterDimAttributeName (boolean _set, BrazilParameters _brazilParameters, Name _name)
{
    DimensionAttribute dimensionAttribute;

    if (_set)
    {
        dimensionAttribute = DimensionAttribute::findByName(_name);
        this.ProfitCenterDimensionAttribute = dimensionAttribute.RecId;
    }

    return DimensionAttribute::find(this.ProfitCenterDimensionAttribute).Name;
}

Also i have created a form extension to include new fields and my intention is to call the edit method right in the new form field to perform the edit operation:

But when i performed the form, the following error showed up:

5873.3808.Capture1.PNG

I can't figure out why this is happened, because the method do exist in the extension. Any guest?

    I just found the mistake in my code. Display and edit method must be STATIC, because under the hood dynamics executes this code from FormUtilClass:

    private static container CallTableDataMethodInExtensionClass(Common _common, str methodName, container inputVariables, boolean newValueIsDefault, str extensionClassName, boolean isStaticMethod)
{
    container returnContainer;
    anyType returnValue;
    boolean set = false;
    anytype newValue;
    int inputVarsSize = conLen(inputVariables);

    DictClass dictClass = new DictClass(className2Id(extensionClassName));
        
    if (dictClass != null)
    {
        DictMethod dictMethod = new DictMethod((isStaticMethod ? UtilElementType::ClassStaticMethod : UtilElementType::ClassInstanceMethod), dictClass.id(), methodName);
            
        if (dictMethod != null)
        {
            // Edit Method
            if (inputVarsSize > 1)
            {
                set = conpeek(inputVariables, 1);
                newValue = conpeek(inputVariables, 2);
                
                // For instance based edit methods parameter count is 2, as instance extension methods is marked as extension methods to C#, but
                // static extension methods are not. So for static extension methods, the check for the 3rd optional parameter is needed.
                int parmOptCheck = isStaticMethod ? 3 : 2;

                // if new value is default and edit method has last argument as optional parameter we want to call method with default argument value.
                if (newValueIsDefault && dictMethod.parameterOptional(parmOptCheck))
                {
                    returnValue = dictClass.callStatic(methodName, _common, set);
                }
                else
                {
                    returnValue = dictClass.callStatic(methodName, _common, set, newValue);
                }
            }
            else // Display method
            {
                returnValue = dictClass.callStatic(methodName, _common);
            }
        }
    }

    returnContainer = conins(returnContainer, 1, returnValue);
    return returnContainer;
}

    Also the order from my edit method was wrong i fix the code and everything worked as expected.
