[Laszlo-dev] method in state confused about scope ?

[Henry Minsky]

I got this error when compiling a test app that uses <dragstate>


  <view id="foo" bgcolor="0xcccccc"
        x="100" y="100"
        height="200" width="200"
        onmousedown="dragger.apply()"
        onmouseup="dragger.remove()">
    <dragstate name="dragger"/>
  </view>


Compiler error: at 38 [/tmp/lzswf9/lzgen22136/$lzc$class_dragstate.as:
18]: Error: Call to a possibly undefined method __dragstate_getnewpos.

this.setAttribute("x", this.drag_axis == "both" || this.drag_axis ==
"x" ? __dragstate_getnewpos("x", this.immediateparent.getMouse("x") +
this.__dragstate_xdoffset) : this.x)
                                                                           ^

Compiler error: at 29 [/tmp/lzswf9/lzgen22136/$lzc$class_dragstate.as:
22]: Error: Call to a possibly undefined method __dragstate_getnewpos.

this.setAttribute("y", this.drag_axis == "both" || this.drag_axis ==
"y" ? __dragstate_getnewpos("y", this.immediateparent.getMouse("y") +
this.__dragstate_ydoffset) : this.y)
                                                                           ^


In lps/components/utils/states/dragstate.lzx, the definition of the x
and y attribute constraints looks like this


    <attribute name="x"
       value="(this.drag_axis == 'both' || this.drag_axis == 'x') ?
              __dragstate_getnewpos('x',
                this.immediateparent.getMouse( 'x' ) +
this.__dragstate_xdoffset)
           : this.x"
        when="always"/>

If I change that function call to have "this.",
"this.__dragstate_getnewpos", then it compiles without complaining.
