트리 클릭시 Cannot read property '__selected__' of undefined

[tpayGhs]

아래와 같이 트리를 생성했는데
Cannot read property 'selected' of undefined -> ax5grid.js:1972
에러가 납니다. 원인이 뭘까요

this.target = axboot.gridBuilder({
target: $('[data-ax5grid="grid-view-02"]'),
showLineNumber: true,
showRowSelector: true,
header: {align:'center'},
frozenColumnIndex: 3,

// item, value
return false;
}
}
},

}
}
],

동일한 이슈가 있었는데, 혹시 필요한 분 계실까봐 제가 수정한 내용 답변 남깁니다.
ax5grid.js 파일에서 수정했습니다.

var doi = this.proxyList[di].__original_index__; 이부분 확인하시면 됩니다.

( 변경전)
while (di--) { if (this.list[doi][cfg.columnKeys.selected]) { pi = this.$.livePanelKeys.length; while (pi--) { this.$.panel[this.$.livePanelKeys[pi]].find('[data-ax5grid-tr-data-index="' + di + '"]').attr("data-ax5grid-selected", false); } } this.proxyList[di][cfg.columnKeys.selected] = false; var doi = this.proxyList[di].__original_index__; }

(변경후)
while (di--) { var doi = this.proxyList[di].__origin_index__; if (this.list[doi][cfg.columnKeys.selected]) { pi = this.$.livePanelKeys.length; while (pi--) { this.$.panel[this.$.livePanelKeys[pi]].find('[data-ax5grid-tr-data-index="' + di + '"]').attr("data-ax5grid-selected", false); } } this.proxyList[di][cfg.columnKeys.selected] = false; }
