Dear Mango Users and Developers, We are running Mango M2M 1.13. We are trying to produce a custom view with relative positioning of elements, so that the graphical view may be viewable on displays for which it was not optimized (i.e. it should scale on resizing). I created a toy graphical view with a button and found the corresponding <div> element. I noticed the style field inside the div element: <div> id="c4" class="selectable" onclick="markViewComponent(this, event);" style="position: absolute; left: 394px; top: 114px; z-index: 0;" > Now I wanted to ask if someone already thought on / implemented already a relative positioning feature. If not, could you give me hints or tips on where to look next? I am thinking of something along the lines of style="position: relative; ...". But then this is not relative to window size but to its "normal" position AFAIK... I would like to get more familiar with Mango and web development in general by solving this problem. Ideally, there should be the ability to set the positioning from the settings editor in p.u. (per unit), e.g. x=0.5, y=0.6, z=0 relative to the current browser window size. As it is now, there are three forms for absolute positioning in the simple point settings editor. If I was more proficient in JavaScript and knew the Mango system better I would also consider calculating the positions on the fly after the window has been resized, i.e. update absolute position values for each view component (?). Best Regards, Michael

Sorry for getting back this late. MA already has a reports module, with which you can generate certain types of reports. I assume that you know this and need something else, in which case you are probably out of luck at the moment As you said, I know these. I use them for daily emailed monitoring reports to check operation. Apart from that, we would like to use our existing reporting facilities (statistical stuff implemented in GNU R) on the MA data. maybe you can let us know whether this is something that would be useful for you Great, this is exactly what I was looking for. This API would help us greatly in building a custom report infrastructure. Thus, a +1 from my side.

Hi All, I am new to Mango environment. Can any one let me know if there are any protocols present to support mobile devices? And is it possible to remotely control mobile devices using Mango server? or does Mango support protocols like OMA-DM?

The details of the license are still being worked out. (Joel did not say this explicitly, but if the case were otherwise i assume he would have pointed you to the license text.) But for certain, it will not be FLOSS.

Oh.. yes i missed that. Now works perfect. Thanks!

hi Cammie, the patch is only for version 1.12.4 and you must apply the patch to the source and then recompile the source. a programmer would have the knowledge required to do this, but for non programmers this may be too difficult

Yes, this is the correct fix. It already made it into 1.13.x, but didn't make it back into 1.12.x.

updated patch against mango 1.12.4. the filedata one places the files in dated directories of the format YYYY/YYYY-MM-DD so I don't have thousands of images in a single directory in 10 years Attachment: download link

updated patch against 1.12.4. (no CSV streamer changes). just includes last image in report period in the report. Attachment: download link

Hi, has anyone seen something like in the attached wireshark trace? Mango is querying a modbus-TCP slave, but somehow loses pace with closing and reopening connections (used with simple TCP, without keep-alive). This slave can only accept one connection at a time, thus the connection will be broken... Thanks, Greg Attachment: download link

Hi, I'm analysing Mango source code. I don't know how JSP pages are connected. For example: the first page is login.jsp (in WEB-INF/jsp/). When user clicks on Log in button, what is the next jsp page that will be shown to him? Where can I define navigation rules? In JSF there is a file faces-config.xml where navigation rules are defined (start JSP page, servlet which checks username and password, and the next JSP page). I imported Mango source code in Eclipse as General/Existing Project into Workspace. Thank you very much! Dusan

This depends from your use case. I would suggest try a search engine and have a look at your (university) library. Arne

Hello everyone, Thanks your topic about building Mango in eclipse, i can now work... but i don't really understand all the sources. So, i wonder if a diagram of the application exists ? or if someone can explain me the architecture of mango ? Thank you for your help ! Carole

Hello, I try to create a new type of data source for my browser (Scada) but I don't know by what it's better to start. Indeed, I must create a new data source to be able to create some point when I link a data source to the browser. This new data source using the protocole snmp for communicate with my entity. Can you explain to me, the step for create (develop) my new data source plz P.S.: Sorry for my bad english, I'm french and I don't speak often. Sincerely Hrer25

@apl said: Thats where further development of mango will happen ...Please don't misunderstand me Arne, but I think you're simplifying too much... Let's try to make things a bit clearer. Perhaps it's time to stop calling this "open source"... just call it freeware since code is no longer available. I'm afraid that for commercial reasons we're gonna loose continuity on one of the best open java projects ever (despite some use of non open packages). Indeed that's probably why scadabr is only a fork and is not officially taking control of mango project. If not them, then who may ever? - Well, there's still VMware... they're acquiring everything! ;) However I must confess I would never call by the name "mango" anything not written by that serotonin developer... But I also think there should be less forks as possible. There are too many forks already in this open source world. In the end, with source provided, maybe people all over the world would likely donate some money for mango support (at least I would). Sorry if I was long, didn't mean to waste your time

Zig have you had any luck on this? I'm doing something similar on a Sheevaplug running Debian with OpenJDK, and it appears to work (sort of) but is ridiculously slow (5+ minutes to load a page). Just wondering if you've gotten anywhere with this. (btw. I'm running mango 12.0).

I suppose it could be done, but then all of the positions of the components in the view would need to be changed accordingly. I presume also that you would want all components to be scaled in the same way as well.

Hi Victor, What version are you seeing this in? I used to see this because the DataPointVO.lastValue property would be set with the latest value of the point, and view initialization depended upon it being different from the current value (because it only sends changes to the browser, and if there is no difference, no change is sent, and the point stays as a block). Personally though, i cannot now recreate the problem. A question though... The above condition should be cleared when the value of the point actually changes. Is this what you are seeing, or does the point always remain a block.

I was asking mwil7034.

@apl: There is already 1.12 version :) You are late!
