I think this is a bug in the Tab Container...
Opening a new tab using Java or the Server Side JavaScript createTab method when the new tab contains a panel that is set to be an iframe pointing to another XPage in the same database will always cause the XPage to get reloaded after loading about five or six tabs (in Chrome, IE does the same but it takes more tabs...)
If the tab contains an iframe that points to another database that holds the XPage it works fine.
The SSJS code is:
getComponent("djTabContainer1").createTab({title:"New tab"});
;
The Java code is
public static boolean createTab(UIDojoTabContainer tabContainer) {
try {
if (tabContainer == null) {
tabContainer = (UIDojoTabContainer) Utils.findComponent("TabContainer");
if (tabContainer == null) {
return false;
}
}
String tabTitle = null;
String url = null;
String unid = null;
UIDojoTabPane newTab = null;
// get default number from current project preferences
tabTitle = "My Tabpage";
url = Utils.GetXpageURL("tabpage.xsp");
// create a new Tab
newTab = new UIDojoTabPane();
newTab.setTitle(tabTitle);
newTab.setTabUniqueKey(new Random().toString());
newTab.setClosable(true);
newTab.setId("TabContainer_" + unid);
newTab.setStyleClass("myTabContainer");
Utils.WriteToConsole("setting style class on " + newTab.getTitle());
// newTab.setStyle("height:auto;width:auto; overflow-y: auto;border: 0px;");
// create new Panel
UIPanelEx newPanel = new UIPanelEx();
newPanel.setId("IFrame" + unid);
newPanel.setStyleClass("iframeClass");
// make an iFrame of this panel with our URL as src
newPanel.setTagName("iframe");
Attr property = new Attr();
property.setName("src");
property.setValue(url);
newPanel.addAttr(property);
// add Panel to our new Tab
newTab.getChildren().add(newPanel);
// add the new tab to our tab container
tabContainer.getChildren().add(newTab);
tabContainer.setSelectedTab(unid);
return true;
} catch (Exception ex) {
Utils.WriteToConsole("Unable to add a new Tab Page to the Tab Container (com.tlcc.Main.createTab)", ex);
return false;
}
}
The XPage that is referenced in the src property of the iframe is very basic...
<?xml version="1.0" encoding="UTF-8"?>
<xp:view xmlns:xp="http://www.ibm.com/xsp/core">
<xp:button
value="Label"
id="button1">
</xp:button>
<xp:inputText id="inputText1"></xp:inputText></xp:view>
When the XPage reloads it has no more tabs (except the first tab that was created in the XPage at the start) and is not responsive.
