【问题描述】：
我有 listGrid:
private com.smartgwt.client.widgets.grid.ListGrid listGrid;
listGrid = new ListGrid() {
@Override
protected Canvas createRecordComponent(final ListGridRecord record, Integer colNum) {
String fieldName = this.getFieldName(colNum);
if (fieldName.equals("toolStrip")) {
HLayout canvas = new HLayout();
canvas.setAlign(VerticalAlignment.TOP);
canvas.setAutoHeight();
ToolStrip strip = new ToolStrip();
strip.setAutoHeight();
strip.setAlign(Alignment.CENTER);
strip.setWidth(90);
strip.setHeight(25);
if (record.getAttributeAsBoolean("requireDoc") && !record.getAttributeAsBoolean("docProvided")) {
ToolStripButton requiredDocButton = new ToolStripButton();
requiredDocButton.setPrompt(conMess.notProvidedDocsPromt());
requiredDocButton.setIcon("attention.png");
strip.addButton(requiredDocButton);
} else {
strip.addSpacer(19);
}
ToolStripButton pdfButton = new ToolStripButton();
pdfButton.setPrompt(conMess.lookInPdf());
pdfButton.setIcon("pdf.png");
pdfButton.setCursor(Cursor.POINTER);
pdfButton.addClickHandler(new ClickHandler() {
public void onClick(ClickEvent event) {
service.generatePdfUser(record.getAttributeAsString("type"), record.getAttributeAsDate("startDate"), record.getAttributeAsDate("endDate"),
record.getAttributeAsInt("numOfDays"), new AsyncCallback<Void>() {
public void onSuccess(Void result) {
String targetURL = GWT.getModuleBaseURL() + "PdfServlet";
Window.open(targetURL, "", null);
}
public void onFailure(Throwable caught) {
}
});
}
});
strip.addButton(pdfButton);
ToolStripButton deleteRecordButton = new ToolStripButton();
deleteRecordButton.setIcon("document_delete.png");
Date formStartDate = record.getAttributeAsDate("startDate");
if ((formStartDate.getMonth() > lastLockedMonth && formStartDate.after(currentDate)) || formStartDate.getYear() > currentDate.getYear()) {
deleteRecordButton.setDisabled(false);
deleteRecordButton.setPrompt(conMess.deleteForm());
deleteRecordButton.setCursor(Cursor.POINTER);
} else {
deleteRecordButton.setDisabled(true);
deleteRecordButton.setPrompt(conMess.deleteMessagePromt());
}
deleteRecordButton.addClickHandler(new ClickHandler() {
public void onClick(ClickEvent event) {
SC.ask(conMess.deletingForm(), conMess.askingForDeleteVerification(), new BooleanCallback() {
public void execute(Boolean value) {
if (value) {
listGrid.removeData(record);
service.updateUserInfoOnRedraw(new AsyncCallback<User>() {
public void onSuccess(User result) {
redrawHeader();
}
public void onFailure(Throwable caught) {
GWT.log(caught.getMessage());
SC.say(caught.getMessage());
}
});
}
}
});
}
});
if (record.getAttributeAsInt("userId").equals(record.getAttributeAsInt("userCreatorId"))) {
strip.addButton(deleteRecordButton);
} else {
strip.addSpacer(20);
}
canvas.addMember(strip);
return canvas;
}
return null;
}
};
listGrid.setHeaderAutoFitEvent(AutoFitEvent.NONE);
listGrid.setWidth100();
listGrid.setShowHeaderContextMenu(false);
listGrid.setShowHeaderMenuButton(false);
listGrid.setAutoFetchData(false);
listGrid.setShowRecordComponents(true);
listGrid.setShowRecordComponentsByCell(true);
listGrid.setCanEdit(false);
listGrid.setLayoutAlign(Alignment.CENTER);
listGrid.setLeaveScrollbarGap(true); listGrid.setCellHeight(25);
dataSource = FormulaireDataSource.getInstance();
listGrid.setDataSource(dataSource);
listGrid.setFields(formId, userId, type, formSent, numOfDays, startDate, endDate, stage_one, stage_one_text, stage_two, stage_two_text, status, status_text, toolStrip, userCreatorId,
requireDoc, docProvided);
// dataSource.fetchData();
listGrid.fetchData();
listGrid.invalidateCache();
listGrid.setHeaderHeight(30);
listGrid.setCanResizeFields(false);
listGrid.sort("startDate", SortDirection.DESCENDING);
listGrid.setCanSort(true);
它在行 listGrid.fetchData() 上抛出此异常（来自上面的代码）：

我通常无法运行该项目。是旧项目，它适用于： GWT 2.5.0 smartgwt 3.0
现在有了： GWT 2.6.0 smartgwt 4.0
我也尝试过 smartgwt 5.0p，但是没有加载 SmartGWTEntryPoint 或类似的东西时出错。所有 smartGWT 版本都是 LGPL 版本。项目的主页正在加载，当我尝试转到 listGrid 时，我看到了错误。在谷歌中没有关于这个错误的信息。我不知道还要补充什么。我确实尝试过多次清理浏览器缓存、重新编译和调试。请帮忙！
