I have a method in the root of my application called "getProxies" that queries a catalog for a given metatype. I have a folder in the root called "Platforms" with a method called "selectInstance" that renders a series of checkbox tags. I call "selectInstance" method from an adjacent folder with <dtml-with Platforms> <dtml-var selectInstance> </dtml-with> This is how this method look at first: <dtml-let control_set="setControl(_, 'PlatformID')" control_name="control_set[0]" control_value="control_set[1]" control_type="'checkbox'" num_columns="3"> <dtml-in getProxies('Platform') sort="Name" prefix="platform"> <dtml-let item="platform_item.id" display_item="platform_item.Name"> <dtml-var inputTag> </dtml-let> </dtml-in> </dtml-let> Doing the above gives a key error for "getProxies", however if I move "getProxies" into the let tag it does _not_: <dtml-let control_set="setControl(_, 'PlatformID')" control_name="control_set[0]" control_value="control_set[1]" control_type="'checkbox'" num_columns="3" proxies="getProxies('Platform')"> <dtml-in proxies sort="Name"> <dtml-let item="id" display_item="Name"> <dtml-var inputTag> </dtml-let> </dtml-in> </dtml-let> It seems like <dtml-let> is doing something with the namespace that makes it impossible for the subsequent <dtml-in> tag to find the "getProxies" method in the root.
