About attachments in flex viewer

EvelynHernandez — Tue, 21 Apr 2015 18:04:30 GMT

Hello,

I am developing an app that needs to add an attachment (pdf file) and save it in the arcgis db. Anyone knows how to do that?

My rest service has the attachment value in True, but idk why this code doesnt do it.

This is part of my code:

myPropLayer.url = "myfeaturelayerurl";

myPropLayer.id = "NewEtaFeature";

myPropLayer.addAttachment(1,byteArrayToProcess,"ElemetopPDF","pdf",new AsyncResponder(resultado,malresultado));

function resultado():void{

Alert.show("saved");

}

function malresultado():void{

Alert.show("not saved");

}

Hi Evelyn,

Your need to provide a valid objectid when you add attachments.

What error are your getting?

Also your resultado() and malresultado() methods need to have events passed as parameter which seems to be missing.

Regards,

Nigel.

Hi Evelyn,

Just correct your code with the following and see if it works.

resultado(event:AttachmentEvent) and malresultado(fault:FaultEvent).

Regards,

Nigel.

  myfeaturelayer.url = "http:...../PMGD/FeatureServer/8";

  myfeaturelayer.id = "NewEtaFeature";
  
  myfeaturelayer.addAttachment(1,byteArr,"ElementoPDF", null,new AsyncResponder(resultado,malresultado));

When you debug this code what error do you get? Also check if your feature service has attachments enabled.

EvelynHernandez — Tue, 05 May 2015 12:18:46 GMT

i cannot debug my app, so when i execute the code i dont get any responde (not true or false)

Re: how to Add attachment in flex viewer

NigelDsouza — Tue, 05 May 2015 17:26:22 GMT

Everything seems to be fine with the code you have written. you can also check the "layer details" property of

the feature layer to check whether attachments have been enabled on your featurelayer.

var layerDetails:LayerDetails = myfeaturelayer.layerDetails

if(layerDetails.hasAttachments)

{

Alert.show("attachments enabled");

savePDF(byteArr);

}

else

{

Alert.show("Please enable attachments");

}

One more thing is, you could try passing the "content type" as a parameter instead of passing null..

myfeaturelayer.addAttachment(1,byteArr,"ElementoPDF", "pdf",new AsyncResponder(resultado,malresultado));

And like i said earlier you need to pass a valid object_id.

And here's a small tip for to get your debugger working.

Assuming that you are working with flash builder it is necessary that the debugger version installed is the same as the version of flash player in your browser.

First check the version of flash player running your browser. Navigate to the following link to check the version Flash Player Help

if it is an outdated version I recommend you update it.

2. Once you've got your flash player version updated/installed navigate to the following link to download the debugger

Adobe Flash Player - Downloads

Select the appropriate debugger and click install.

3. Then insert some breakpoints,run your app in debug mode and i think your off..

Actually its really hard to suggest any solution cause your code seems fine... i guess through a debug session you might be able to track some errors..or maybe some section of code that isnt getting called.. hence the expected output is void.

Hope this helps.. do get back,...

Regards,

Nigel.

The code that u send me doesnt do anything, but in my rest srv i have the has attachment in true.

Im downloading the debugger.

And i also tried putting the "PDF" in the content type but still doesnt work.

Idk what more i should do...

Did the debugger work?

Re: how to Add attachment in flex viewer

EvelynHernandez — Wed, 06 May 2015 12:32:43 GMT

No. I installed it and fb still doesnt recognize me the debugger.

It tries to make the connection and got an error with the following msg: "Flash builder cannot locate the requited debugger version of adobe flash player....."

I put that i want to try the debug with the current version and it tries to load the app but nothing happens.

So, i think if anyone can provide me any working example using attachment for PFD and any file will be better,,, (W/o using the attachment inspector)

Thanks for all ur help as always.

Probably the flash player version and the debugger version you installed isn't the same.

For example if you debug in IE and the flash player version is 17 then the debugger exe should be something like

"flashplayer_17_ax_debug.exe" and the link would be something like "Download the Flash Player content debugger for Internet Explorer - ActiveX".

As far as the code is concerned ill send you one soon.

The only thing is maybe the add attachments code block isn't getting executed probably that's why it isnt entering the result or fault methods.

Nigel.

In fact, i usually do some debug on the apps with Alert.show(); but in this case my point is, the addAttachment method doesnt make anything. Its like the code goes to the line before the addAttch and when go to the addatch line the function doesnt do anything.

Its weird cuz atleast if the adding fails has to go to the fault result, or if its successful, go to the onresult function, but even with those controls doesnt do anything.

About the debug.exe i installed the one u just link me. But i always get the same error. Its strange.

Thanks i will be waiting for ur working example for this. I really appreciate all ur answers

Re: how to Add attachment in flex viewer

NigelDsouza — Wed, 06 May 2015 17:59:21 GMT

Actually i have successfully done the add attachments task using the android sdk.

So ill prepare one in Flex and send it ASAP.

Give me a day or 2.

Until then you can try and get the debugger to work.. plus it'll make your debugging alot easier

Hi Evelyn,

I have prepared a small widget for you..

like I said your code is perfect.. just change

the "AttachmentEvent" event into "FeatureEditResult"

so this "function resultado(event:AttachmentEvent):void" would look like

function resultado(event:FeatureEditResult):void

However you can use my widget as a reference..

I did get a successful result.

I have used an online ArcGIS service in the example that uploads a txt file.

Here's a Google drive link to the following widget. You can directly included it in your app and run it .

Test.zip - Google Drive

If you get a successful result you can navigate to the featureLayer link in yout browser "Feature Layer: Incidents (ID: 0) " append the objectid passed as a parameter, so your link would look like this

"http://sampleserver3.arcgisonline.com/ArcGIS/rest/services/SanFrancisco/311Incidents/FeatureServer/0/14682516"

hit enter and you should be navigated to the record. Then click on the Attachmentinfos link to view your attachment.

I hope this helps you.

Regards,

Nigel..

NigelDsouza — Thu, 07 May 2015 16:56:59 GMT

Most welcome

Where was the error at?

Did the sample I sent help you?

Regards,

Nigel

Re: how to Add attachment in flex viewer

EvelynHernandez — Thu, 07 May 2015 17:08:26 GMT

Yes ur example works perfectly. the error was in the onresult maybe and the addatch sentence.

I have another question. If u want to do a delete or update on one especified attch how will it be the featurelayer.addattachment sentence for both cases?

Or i have to use another method to do that?

Thanks
