Hi

I have an xtend expression that is supposed to returns: String but it returns [String].

This is the xtend expression

import NETSTMM;

String datatypeconv(NETSTMM::Languages l,NETSTMM::DataTypeKind partype ):
if l.toString().trim()=='vbnet' then
	{if (partype!=null) then
		switch (partype.toString()) {
		case 'DateTime':'Date'
		case 'int':'Integer'
		case 'Bool':'Boolean'
		case 'decimal':'Decimal'
		default: partype.toString().trim()
		}
	else
		"String"
	}
else
	switch (partype.toString().trim()) {
	case 'Date':'DateTime'
	case 'String':'string'
	case 'Integer':'int'
	default: partype.toString() 
	} ;

this is the xpand template to call it

ByVal «M.NMthHasPar.PName» As «datatypeconv(M.NMBelongsMC.MCBelongsPr.PrLanguage,M.NMthHasPar.first().PType)» _

and this is the result

Quote:

ByVal Param1 As [String], _

but I need it to retuns

Quote:

ByVal Param1 As String, _

Any ideas?

hi,

the {} operator creates a List
{"a"} gets [a] if you call to String on it / it is printed in the template.

so with

if l.toString().trim()=='vbnet' then {
...
} else
...

you construct a list in the if case.
