If there are binding source path properties in root node on HButton template qml file,  source path properties' replacement isn't done in a way we want during component merging. it is  just only  property name and value(path) with no "property string"  keyword. so then, merged qml file causes a warning message of invalid on QDS. 

 

• - before merging –

import ccOS.GUI.Controls 2.0

T.Button {
id: control
objectName: "HButton"
property string backgroundSrc: relativeBGPath

 

background: HNinePatchImage

{            id: innerBackground }

}

 

– after merging –

import ccOS.GUI.Controls 2.0

T.Button {
id: control
objectName: "HButton"
backgroundSrc: "assets/bco_btn_bg_bottom"

 

background: HNinePatchImage

{            id: innerBackground }

}
