Error with JavaScript on XDP form rendered as HTML

Avatar

Level 3

I have saved a form as an XDP and am rendering it as HTML with LiveCycle Forms Server ES. When I click on certain form buttons that cause JavaScript code to fire, I get the following error:

this._peer is undefined

I've seen this error posted in a few Adobe forum posts without answers. Any ideas?

The buttons that are generating the errors are they buttons that you have jkavascript behind or are they submit buttons?

They are buttons that I have JS behind. The submit buttons work fine.

Can you post the code that you have behind those buttons? Is it set to run at Client or at Server?

Here's a snippet of the button that runs the JS. It's really long, so I cut out most of the JS. I can post the whole thing if you want. It is set to run at the client.

<input class="fsc33 fsc21 fsc22 fsc2" id="NButton2_0" name="Button2[0]" onclick="return this._peer._clickfunc(***JS REMOVED FROM POST TO SAVE SPACE***)" type="button" value="Insert Clause" />

I was looking for the code that you added to the button ……in Designer what type of button is it and what do you expect that button to do when it is clicked?

It is a regular button that fires code that does a popup dialog box. It works fine when the form is rendered as a PDF; I get the "this._peer is undefined" error when I render it as HTML and try to run the code. Here's the code:

var insert_clauses =

{

result:"cancel",

DoDialog: function(){return app.execDialog(this);},

strpop1:"",

SetListSel:function(list,path){if(path.length == 0) return;

eval("list[\""+ ((typeof path.join != "function")?path:path.join("\"][\"")) + "\"] = 1")},

GetListSel:function(oLstRslts,path){

   for(var item in oLstRslts){

      if( ((typeof oLstRslts[item]=="number")&&(oLstRslts[item]>0))

         || this.GetListSel(oLstRslts[item],path) )

       {path.push(item);return true;}

   }

   return false;

},

initialize: function(dialog)

{

//this.xfa.form.Ultra_Form.Page1.clauses.rawValue;

//var listpop1 = {"Clause1": -1,"Clause2": -2}

var listpop1 = {};   

//listpop1["Select a clause to insert"] = 1;

//xfa.resolveNode("xfa.datasets.data.Ultra_Form.Page1.clauses").value

var arrClauses = xfa.resolveNode("xfa.datasets.data.Ultra_Form.Page1.clauses").value.split("||"); //

var num=0;

while (num < (arrClauses.length))

{

  var test = arrClauses[num];

  listpop1[test] = -num;

  num+=1;

}

//dialog.load({"pop1": listpop1});

this.SetListSel(listpop1, this.strpop1);

var dlgInit =

{

"pop1": listpop1,

};

dialog.load(dlgInit);

},

commit: function(dialog)

{

var oRslt = dialog.store();

var path = new Array();

this.strpop1 = (this.GetListSel(oRslt["pop1"],path))?path.reverse():"";

},

The JS I put on this link produces the same error:

<a href="#" tabindex="4" onclick="return this._peer._clickfunc(&quot;\nxfa.host.print(1, \&quot;0\&quot;, (xfa.host.numPages \-1).toString(), 0, 0, 0, 0, 0);\n&quot;)">Print</a>

That’s your issue ….the app object is not known when you render as an HTML page. You may want to change this to an xfa.host.messageBox or use a native javascript dialog box (remember that you are running in a browser as HTML).

Hmm....doing a test with xfa.host.messageBox didn't seem to work either:

<input class="fsc20 fsc21 fsc22 fsc2" id="NButton3_0" name="Button3[0]" onclick="return this._peer._clickfunc(&quot;\nxfa.host.messageBox(\&quot;yeah this worked\&quot;);\n&quot;)" tabindex="276" type="button" value="Button" />

I still get the "this._peer is undefined" error. It seems like any time I try to use onclick="return this._peer._clickfunc()" I get this error.
