gwt-maps-1.0.4.jar and gwt-user-1.5.3

[everlongh]

I noticed a dependancy between the new gwt-maps and gwt-1.5.3.

I am having some issues with my maps application using the new
jars...original code works fine with gwt-maps-1.0.2 and gwt-1.5.3...

Here one exception I get with no code changes:



link.addClickHandler(new ClickHandler() {
@Override
public void onClick(ClickEvent event) {
// remoteService.remoteMethod("Hi Server", callback);
final Widget sender = (Widget) event.getSource();
if (sender instanceof Hyperlink) {

final Hyperlink link = ((Hyperlink) sender);

System.out.println("Polling link ="
+ link.getTargetHistoryToken());

link.setText("Polling...");

final String key = link.getTargetHistoryToken();
// int index = html.indexOf("?");
// final String key = html.substring(index);

// link.setHTML("Polling site...");

Timer t = new Timer() {
public void run() {

// Window.alert("Site "+key+" ATG's could not be reached.");
// Window.alert("Site ATG's could not be reached.");
TankInventoryVO[] tivos = inventoryVOMap.get(key);

for (int x = 0; x < tivos.length; x++) {
TankInventoryVO tivo = tivos[x];

DateTimeFormat formatter;
formatter = DateTimeFormat
.getFormat("yyyy.MM.ddHH:mm:ss");

Date date = new Date(System.currentTimeMillis());

String dt = formatter.format(date);
tivo.setInventoryDateTime(dt);
// tivo.setInventoryDateTime("2009-03-04 12:15:00");

double volume = tivo.getInventoryVolume();
volume = volume - Random.nextInt(100);

tivo.setInventoryVolume(Float.parseFloat(Double
.toString(volume)));
tivo.setVolumeUom("gal");
String divId = key + "-TankInventory-" + x;
System.out.println("Updating panel for "
+ divId);
RootPanel.get(divId).getElement().setInnerHTML(
getTankInventoryForMapTree(tivo));
}

link.setHTML("Poll Now");

}
};
t.schedule(5000);

}


}
});

Hi,

I see your code, but I don't see any code in gwt-maps being called (at
least, not directly) and I am not sure what exception you are
referring to.

Sorry, I thought I had included the exception... here it is below, it
occurs on the line

RootPanel.get(divId).getElement().setInnerHTML(

getTankInventoryForMapTree(tivo));

The link in the code is inside a gwt-,maps InfoWindow

link.addClickHandler(new ClickHandler() {
@Override
public void onClick(ClickEvent event) {

I do not get the excpetion with gwt-1.5.3.

So, what is the code at:

at com.fuelquest.darkstar.client.DarkStar$14$1.run(DarkStar.java:
1062)

[everlongh]

here it is below, it occurs on the line

RootPanel.get(divId).getElement().setInnerHTML
(getTankInventoryForMapTree(tivo));

DEBUGGED BACK TO... RootPanel.get(divId)

In RootPanel.java

// Create the panel and put it in the map.
if (elem == null) {
// 'null' means use document's body element.
rp = new DefaultRootPanel();
} else {
// Otherwise, wrap the existing element.
rp = new RootPanel(elem);
}

rootPanels.put(id, rp);
detachOnWindowClose(rp);
return rp;

[everlongh]

Just to be comletely clear the div id being updated is html in a
com.google.gwt.widgetideas.client.FastTree widget inside a map marker
infowindow

below is the code that adds the widget

private void addInfoWindowWidget(final Marker marker, final Widget
widget) {

marker.addMarkerClickHandler(new MarkerClickHandler() {
public void onClick(MarkerClickEvent event) {
InfoWindow info = map.getInfoWindow();
InfoWindowContent content = new InfoWindowContent(widget);
info.open(marker, content);
}
});
}

The FastTree that has html with the divID updated in the loop below,
each tree node html gets update with a call
to RootPanel.get(divId).getElement().setInnerHTML
(getTankInventoryForMapTree(tivo));

The whole loop is below:

for (int x = 0; x < tivos.length; x++)
{
TankInventoryVO tivo = tivos
[x];

DateTimeFormat formatter;
formatter = DateTimeFormat
.getFormat
("yyyy.MM.ddHH:mm:ss");
Date date = new Date
(System.currentTimeMillis());
String dt = formatter.format
(date);
tivo.setInventoryDateTime
(dt);

double volume =
tivo.getInventoryVolume();
volume = volume -
Random.nextInt(100);
tivo.setInventoryVolume
(Float.parseFloat(Double
.toString
(volume)));
tivo.setVolumeUom("gal");
String divId = key + "-
TankInventory-" + x;
System.out.println("Updating
panel for "
+ divId);
RootPanel.get(divId).getElement
().setInnerHTML(

getTankInventoryForMapTree(tivo));
}

I think the problem is that you are clobbering a tree in the DOM using setInnerHTML() that you created with GWT widgets.  Can you find a way to comment out the setInnerHTML() or attach to the div some other way?

I have a similar problem that only started when I started using GWT
1.6.

In my code I create a fieldset HTML elememt and add it to a flex table
thus.

<code>
public static HTML createFieldSet(String as_legend, String
div_element_id) {
return new HTML("<fieldset>"
+ "<legend>" + as_legend+ "</legend>"
+ "<div id='" + div_element_id + "'></div>"
+ "</fieldset>");
}

HTML html = createFieldSet("My Fieldset", "MYID");
FlexTable table = new FlexTable();
table.setWidget(0, 0, html);
</code>


In the onload method of my window, I then inject a new widget into the
ID for the fieldset div with ID "MYID" as follows

Widget somewidget ...
RootPanel.get("MYID").add(somewidget);

I get the same error as described above in hosted mode. In web mode it
works fine.


I tired using the following to fix the problem.

<code>
Element p = DOM.getElementById("MYID");
p.appendChild(somewsidget.getElement());
</code>

THis works in hosted mode but fails in web mode.

Any ideas?

Thanks,
