Problems w/ dot-annotation in custom attributes

[johncorro]

I've created a subclass to dataset (rpcdataset) that has two custom attributes: "controller" and "method". When I attempt to create a new instance of rpcdataset, I'll pass in a dot-annotated value for the controller attribute.

<rpcdataset controller="com.foo.bar" method="bah"/>

When I do this, though, Laszlo complains that "com" and "foo" are undefined and that it can't find attributes "foo" and "bar" on them (respectively). However, when I changed my code to

<rpcdataset controller="${'com.foo.bar'}" .../>
everything seems to work fine.

Does anyone know why this is? I'd like to not be forced to have to wrap all my controller values in ${''} if at all possible.

I've tried the solution posted at

but it doesn't seem to work. Any help would be appreciated.

Hi John,

Attributes default to an expression type. To ensure that your type is a string, you need to declare it like:


<attribute name="controller" type="string" />


Another way of setting your controller to string is:


<rpcdataset controller="'com.foo.bar'" .../>


That is equivalent to this:


<rpcdataset controller="$once{'com.foo.bar'}" .../>


Hope this helps.
