Re: Re: Use beforeSave() for validation and display error message

Hi Chris,

Thanks for pointing to the use of form tools validation methods. However,
how would I get the error message displayed on my custom type edit form?

I have the property set to:

<cfproperty ftseq="50" ftFieldSet="Login" type="string" ftLabel="Username"
name="username" ftType="string" ftValidation="required" bLabel="true">

Then I have my validation method as:

<cffunction name="ftValidateUsername" access="public" output="true"
returntype="struct" hint="This will return a struct with bSuccess and
stError">
<cfargument name="objectid" required="true" type="string" hint="The
objectid of the object that this field is part of.">
<cfargument name="typename" required="true" type="string" hint="The name of
the type that this field is part of.">
<cfargument name="stFieldPost" required="true" type="struct" hint="The
fields that are relevent to this field type.">
<cfargument name="stMetadata" required="true" type="struct" hint="This is
the metadata that is either setup as part of the type.cfc or overridden
when calling ft:object by using the stMetadata argument.">
 <cfset var stResult = structNew()>
<cfset var qDuplicate = queryNew("blah")>
<cfset stResult = createObject("component",
application.formtools["field"].packagePath).passed(value=stFieldPost.Value)
/>
 <!--- --------------------------- --->
<!--- Perform any validation here --->
<!--- --------------------------- --->
<cfquery datasource="#application.dsn#" name="qDuplicate">
SELECT objectid from userProfile
WHERE upper(username) = '#ucase(stFieldPost.Value)#'
</cfquery>
 <cfif qDuplicate.RecordCount>
<!--- DUPLICATE USERNAME --->
<cfset stResult = createObject("component",
application.formtools["field"].packagePath).failed(value="#arguments.stFieldPost.value#",
message="The username you have selected is already taken.") />
<!--- <cfdump var="#stResult#"><cfabort> --->
</cfif>
 <!--- ----------------- --->
<!--- Return the Result --->
<!--- ----------------- --->
<cfreturn stResult>
 </cffunction>

If I dump out the stResult, I can see ftValidateUsername is invoked and it
correctly detected the duplicates and set the error message:

struct BSUCCESS false  STERROR  struct CLASS validation-advice  MESSAGE The
username you have selected is already taken.    VALUE flyingturtle123

However, without abort execution, it still saved the record and not
displaying the validation message anywhere.

Am I missing sth here?
