angularjs - Input file error in lumx -


in directive, i'm trying use input file lumx following error:

<div flex-item>     <lx-file-input label="browse..." id="files" ng-model="file"></lx-file-input> </div>

error: [$compile:nonassign] expression 'undefined' used directive 'lxfileinput' non-assignable! http://errors.angularjs.org/1.3.15/$compile/nonassign?p0=undefined&p1=lxfileinput

also, in official documentation lumx (http://ui.lumapps.com/directives/file-inputs), if check in console log, you'll see same error.

how can fix this?

i found reason, if encounter same issue. must need value attribute, this:

<lx-file-input label="browse..." value="file" id="files" ng-model="file"></lx-file-input>
