Posted by iDempiere ERP. Workflow Editor 預設的編輯的欄位數為4個。 （圖 1）
在較複雜的Workflow設計圖時，可能就不敷使用。本篇文章說明如何修改Soruce code來增加欄位。
在 JIRA 提供 Patch檔或參考下列說明。
https://idempiere.atlassian.net/browse/IDEMPIERE-5431
我們在工作列上增加一個 NumberBox，可以用來任意調整Workflow 畫布的欄位數。變更後按Refresh即可變更畫布欄位數。（圖 2）
畫布欄位數預設值為 4， 也可以透過System Configuration 來設定預設值 (關鍵字為 WORKFLOW_EDITOR_COLUMNS）
org.adempiere.webui.apps.wf.WFNodeContainer 增加一個 setNoOfColumns method
public int getNoOfColumns() {
return noOfColumns;
}
public void setNoOfColumns(int noOfColumns) {
this.noOfColumns = noOfColumns;
}org.adempiere.webui.apps.wf.WFEditor
增加一個 NumbreBox
private NumberBox columnsBox;在initForm method中，將NumberBox 加入Toolbar
NumberBox預設值為4，
columnsBox = new NumberBox(true);
columnsBox.setValue(MSysConfig.getIntValue("WORKFLOW_EDITOR_COLUMNS", 4,Env.getAD_Client_ID(Env.getCtx())));
toolbar.appendChild(columnsBox);在 load method 中加入
nodeContainer.setNoOfColumns(columnsBox.getValue().intValue());
for(int c = 0; c < 4; c++) {
改成下列程式碼
for(int c = 0; c < columnsBox.getValue().intValue(); c++) {
WFNodeContainer及WFEditor 完整程式如下。
