Hello everyone,
I am using auto-sort table component in jspx pages of my application. I am explaining my problen giving the following example: the table has a column named 'City', and the script is

ice-cc:column title="City" value="#{row.cities.tag}" name="cities.tag" sortable="true"

The rows of the table have null and not null values for this field.
When I first display the table, no error is seen in the log files. But, if I try to sort the table in the browser, by the field 'City', then errors are displayed in the log file (but not in the browser). These errors tell that Null property value for 'cities.tag'.
The situtation is this:
the object 'Cities' is null and I want to know if there is any way to sort by a column even if it has null values and no error is generated. Because in my case there can be null values in fields.
Thank you :)

Hello,

We are using Icefaces 1.7.2 inside our project. We decided to change to Icefaces 1.8.1..

After we switched to 1.8.1 and deployed our project to Glassfish v2 we started having problem with the communication with our server.

Using Firebug we noticed that the server does not send his pong reply. . And after three unsuccessfully attempts of the heartbeat pings to get a pong response, we get the "Network Connection Interrupted" message.

We were obligated to turn back to Icefaces 1.7.2.

Could anybody help us with this problem. Is it a 1.8.1 bug or we are doing something wrong.

Thank you in advance for any suggestion you could give.

Hello to all,

I am struggling to find a way to get the position of a ice:commandLink or any ice component (top, left coordinates) from a managed bean.

Please can someone tell me if exist a way to do that, or am I wasting my time????

Thanks.
Regards

Hi Toms,

I think I am going to use GeoTools as it is the base library for almost all the other Java GIS opensource environment as GEoServer is. And also I need to have a complete control on my shapefiles.
I need to add shapefile layers based on user input, change object styles, get map coordinates on user click and so on. By now I was able to render a shapefile on an GraphicImage component, and now I am searching a way to get the coordinates from the user clicking on the map. If you could help me on this .... then many thanks.

Regards.

Wolf, I took a look to the Resource componet is it is very nice.
We decided to use it to generate pdf reports that are a very esencial part of our project. I think I can use it also for the map. During the weekend I was able to render a shapefile map into an ice:graphicImage

It is very important to me to be able to get the coordinates of the map from the image. I thought that if I can get the image coordinate of the mouse and send them to a managed bean, I can then transform them into realworld coordinates, and with that thing all my problems with be resolved (I hope so :))

I also tried to get the coordinates of the map from the image but I couldn't do that. I tried using a java script code and load the function on the onclick event of the ice:graphicImage, but with no result.

Can somebody help me on this thing?? Thanks.

And Tom, thanks for you post. But as I previously wrote I need to have my project only on an opensource environment, so I can not use the AcrGIS Server thus I can not use your ESRI-WebADF libray.

Thank you all for your replies.

I had a look to OpenLayers and ArcGis/ICEFaces integration.

In my project I am going to use maps to show statistics that will be generated at runtime by reading the data from an oracle database. So I need to have a programatic control on the map, lets say to add layers, remove, layers, change style (layers are shapefiles or coverages), add elements (points) on maps and so on.

It seems to me that all this work is difficult to manage with the openlayer component.
And about ArcGis component, I am interested more in an opensource solution and if I am not wrong the ESRI ArcGIS Server Java 9.2 is a commercial product.

I think that using Geotools would be the best solution for me as there is a lot of capabilities to manupulate maps. But I would need some help on the way to render the shapefiles maps on an image, and how to listen the events on the image (get coordinates).

TheWolf you mention something about the new resource component with geotools. Could you please be more specific and if you can post any example I would be very grateful.

Thanks a lot for your replies again.

Hello to everybody.

I am working on a web project that uses IceFaces technology. It is really great.
We have sme shapefiles (ESRI format) and we need to incorporate them into our web site. Is there a way to render GIS maps (shapefile or coverages format) on the web using Iceface. I was lookin on GeoTools but I am not eing able to figure out how this can be done on a web-based application with JSP.

Any idea, any help with be really appreciated.

Thanks in advance.
