Noel Grandin commented on PIVOT-804:
------------------------------------
Comment from Chris Bartlett:
It is due to the different setters in the TabPane's skin.
http://pivot.apache.org/2.0/docs/api/org/apache/pivot/wtk/skin/terra/TerraTabPaneSkin.html
The 'buttonPadding' style only has explicit setters for Insets and int
void setButtonPadding(Insets)
void setButtonPadding(int)
But 'padding' has setters for these.
void setPadding(Dictionary<String,?> padding)
void setPadding(Insets padding)
void setPadding(int padding)
void setPadding(Number padding)
void setPadding(String padding)
> Why can't I set a TabPane's buttonPadding to a dictionary?

> I must be missing something really obvious here. TablePane happily
> accepts a padding value expressed as a dictionary. So does Label.
> But when the bxml serializer gets down to the TabPane below where I
> try to set its buttonPadding to the same dictionary, it barfs, saying
> "Unable to coerce org.apache.pivot.collections.HashMap to class
> org.apache.pivot.wtk.Insets". Aren't the padding values also of type
> Insets? What am I doing wrong?
> <Window xmlns="org.apache.pivot.wtk">
> <TablePane styles="{padding:{left:10,right:10,top:5,bottom:5}}">
> <columns>
> <TablePane.Column width="1*" />
> </columns>
> <TablePane.Row>
> <Label text="Some text"
> styles="{padding:{left:10,right:10,top:5,bottom:5}}" />
> </TablePane.Row>
> <TablePane.Row>
> <TabPane styles="{buttonPadding:{left:10,right:10,top:5,bottom:5}}" >
> <BoxPane TabPane.tabData="Test" />
> </TabPane>
> </TablePane.Row>
> </TablePane>
