You must have an argument for Datasource setup in the MakeBreadCrumb function that is required. You either have to pass datasource into the function. A quick example:

or make the argument not required.

Thank you very much, finally help from someone. :)

However I don't see any of the code you might have pasted in here. It would be nice if you could try to paste it again, because I am not really sure I understand what you mean by having a "datacource setup in the MakeBreadCrumb function". You see, I thought it is enough to pass it ftrough "cfargument" in the function definition and with an "cfinvokeargument" in the invoke definition, as I actually did in the code.

Also I already tried having the arguments in the function set on required="no", but even that didn't work - which for me as a programmer was quite logical, cause if there is no argument passed correctly, than the required field shouldn't make any difference if enabled or disabled in case that I am actually not passing any argument. I think it's a nice solution passing arguments like this, having the required field set as "yes"... only I have to figure out how to do it properly (if I would see your code example). If the argument would be passed correctly, then the required option could stay as it is: required="yes". Am I right?

Also now I see that in this forum we cannot paste any HTML or CF code, because it doesn't show it. Will have to suggest to the author of this comunity to add the [code][/code] tags possibility. Wouldn't that be great?

Opps I missed that it didn't add my example. Anyways the error that you are getting is typically related to required arguments that are not being passed in when the function is invoked. It is odd that you are getting the same error when setting the required="false" to the argument itself. Here when you invoke try this, I am not going to past the carrots so pretend they are there haha:

cfinvoke component="component" function="MakeBreadCrumb" datasource="value"

Hm... but I am doing exactly that, except that I think you meant "method" instead of "function". :)
I mean like this:

cfinvoke component="component" method="MakeBreadCrumb" datasource="value"

Have you checked my code here?

BTW, wouldn't it be nice that we could be able to post code in the same way as we can do it in some other forums, such as on the link I pasted above?

opps my bad yes I ment method not function. instead of doing this:

cfinvoke
component="cfdocs.Recursive Navigation.cfcomponents.navigation"
method="MakeBreadCrumb"
returnvariable="MakeBreadCrumbRet"
cfinvokeargument name="id" value="#URL.item#"/
cfinvokeargument name="cnt" value="1"/
cfinvokeargument name="dataSource" value="#databaseSource#"/
cfinvokeargument name="table" value="#sourceTable#"/
/cfinvoke

try this
cfinvoke
component="cfdocs.Recursive Navigation.cfcomponents.navigation"
method="MakeBreadCrumb"
returnvariable="MakeBreadCrumbRet"
id="#URL.item#"
cnt="1"
dataSource="#databaseSource#"
table="#sourceTable#"
/cfinvoke

I am determined to figure this out haha. I am now trying to recreate issue on my local box. Maybe I can get it to break as well.

Also do you have a default value set for the argument that you are now set to not required? I know that Coldfusion doesn't like when an argument is not passed in and a default value is not set.

Nope, tried already to set up the default option in the function. It still doesn't find any argument from outside. I tried to set the default value to default="" and of course the error report says:

"Datasource '' could not be found."

So It is true that the arguments don't come from outside! If you will check my code, you will see that's really odd, cause it excepts the first two out of four arguments, but it doesn't "see" the last two:

cfargument name="dataSource" type="any" required="yes" default=""
cfargument name="dataTable" type="any" required="yes" default=""

So that's really odd.

Also, what version of Coldfusion are you running? It may help I suppose because now you can set this.datasource on the application page and you may be getting variable scope issues.
