How to get the messages in a conversation

[morten]

I am trying to make a zimlet which sends items dropped on a panel item to another server.

When I drag a mail message to the panel item I always get a conversation object, even if it is one message. How do I retrieve the most recent mail message?

I have looked in the javascript libraries for the ZmConv class but I do not know how this class got initialized. I can get the numMsgs and the fragment, but how do I retrieve the messages and if I have the messages, how do I get the body?

You can look at this zimlet code (retrieve messages but in a jsp page):

How do I retrieve the most recent mail message?

After you retrieve your ZmConv object, you maybe can use the method getFirstHotMsg to retrieve a ZmMailMsg object, and after you can retrieve the body with the body param of ZmMailMsg (obj.body).

When I try to execute the getFirstHotMsg I get the following in the error console:

Error: conversation.getFirstHotMsg is not a function
Source File: https://------/service/zimlet/_dev/n...=1211374524110
Line: 74

i have also tried to execute the toString() function but I keep getting Object back instead of the ZkConf text. But if I execute numMsgs and fragment do return values!

It is not normal it don't work, you lack a parameter.
Here is the method from ZmConv.js (source code from version 5.0.2) :

/**
 * Returns the first matching msg of this conv, loading the conv msg list if necessary. If the
 * msg itself hasn't been loaded we also load the conv. The conv load is a SearchConvRequest
 * which fetches the content of the first matching msg and returns it via a callback. If no
 * callback is provided, the conv will not be loaded - if it already has a msg list, the msg
 * will come from there; otherwise, a skeletal msg with an ID is returned. Note that a conv
 * always has at least one msg.
 * 
 * @param params	[hash]	hash of params:
 *        query				[string]*		query used to retrieve this conv
 *        sortBy			[constant]*		sort constraint
 *        offset			[int]*			position of first msg to return
 *        limit				[int]*			how many msgs to return
 * @param callback			[AjxCallback]*	callback to run with results
 */
ZmConv.prototype.getFirstHotMsg =
function(params, callback) {
	
	var msg;
	params = params || {};

	if (this.msgs && this.msgs.size()) {
		msg = this.msgs.getFirstHit(params.offset, params.limit);
	}

	if (callback) {
		if (msg && msg._loaded) {
			callback.run(msg);
		} else {
			var respCallback = new AjxCallback(this, this._handleResponseGetFirstHotMsg, [params, callback]);
			params.getFirstMsg = true;
			this.load(params, respCallback);
		}
		return;
	} else {
		// do our best to return a "realized" message by checking cache
		if (!msg && this.msgIds && this.msgIds.length) {
			var id = this.msgIds[0];
			msg = appCtxt.getById(id) || new ZmMailMsg(id);
		}
		return msg;
	}		
};

More info:

I have tried to do obj instanceof ZmConf to check if it knows that it is a subtype of that class but then I get the error that ZmConf is not defined.

I have really no idea what is going on!
The objects passed to doDrop are of type ZmMailMsg, ZmConf, etc. or not?

[morten]

Even if I pass the arguments to getFirstHotMsg it says it is not a function. Somehow it seems that the obj passed to doDrop is not really a ZmConf class

[tdesorbaix]

It is not ZmConf but ZmConv.

[morten]

I am still at loss, I really do not understand what type of objects are returned by the different methods.

Now i tried the following with a ZmConv object:

	var ajxCallback = new AjxCallback(this, this._done_getMsgsForConv, conversation);
	this.getMsgsForConv( ajxCallback, conversation );

and in the callback:

xxxxx.prototype._done_getMsgsForConv = function( conversation, message )
{
	//Process message
	alert( "body content: " + message.getBodyContent() );
};

The getBodyContent function is defined in ZmMailMsg but when I call the function I get the error:

Error: message.getBodyContent is not a function

What do all these methods return!!! I just want to have the full email details so that I can create a rpc call to another service.
