Empty TabContainer in Dojo Dialog - dojo

Question

The problem is that the TabConainer inside the Dialog is empty after opening although selected="true" is given (see the screenshot below). The content is called with dojo/html html.set(node, contentHTML, {parseContent: true});
When changing the tab by clicking on another one the content appears and the class "dijitVisible" is set for this div as it should be from the beginning. The attribute nested="true" is necessary since otherwise three select bars are shown over the tabContainer.
What can I do so that the content appears from the start on?
<div data-dojo-type="dijit/Dialog" id="formDialog" data-dojo-id="formDialog" title="Edit member data">
<div id="formContent" class="dijitDialogPaneContentArea" data-dojo-attach-point="formContent">
</div>
</div>
Update:
Here is the whole javascript for getting the content
getForm = function(formID, urlAction){
var contentHTML;
var xhrArgs = {
url: urlAction,
handleAs: "text",
load: function(data){
contentHTML = data;
},
error: function(error){
contentHTML = text_error_unexpected + ": " + error;
},
handle: function(error, ioargs){
var node = dom.byId(formID);
html.set(node, contentHTML, {parseContent: true});
}
}
var deferred = dojo.xhrGet(xhrArgs);
};
Update 2:
This is the content that gets called and inserted in the above div "formContent" (I thought I make the description as simple as possible and lost some details on the way)
<div id="form" data-dojo-type="dijit/form/Form" data-dojo-attach-point="form" encType="multipart/form-data" action="#">
<div style="width: 450px; height: 370px;">
<div data-dojo-type="dijit/layout/TabContainer" nested="true">
<div data-dojo-type="dijit/layout/ContentPane" title="Personal data" selected="true">
Content 1
</div>
<div data-dojo-type="dijit/layout/ContentPane" title="Detailed data">
Content 2
</div>
<div data-dojo-type="dijit/layout/ContentPane" title="Contact data">
Content 3
</div>
</div>
</div>
</div>

Answer 1

Have you tried calling either dialog.resize() or tabcontainer.layout() after adding it to the dialog?

Answer 2

I am not sure as to how the code below will place contents inside the first ContentPane (title="Personal data"). I am assuming that the parameter formID = "form"
html.set(node, contentHTML, {parseContent: true});
I can suggest an alterantive.
Use an id with the content pane as shown below.
<div id="content1" data-dojo-type="dijit/layout/ContentPane" title="Personal data" selected="true">
Content 1
</div>
Then use dijit/registry to get the contentpane widget in the handle function call as shown below.
handle: function(error, ioargs){
var content= registry.bId(formId); // over here formId = "content1"
content.set("content","<p>This is content for <b>Personal Data</b></p>");
//content.set("content", contentHTML);
}
EDIT 1
This is may be one possible solution.
#Richard had suggested dialog.resize(), which I did try to put it after the html.set code but it would not work.
What I have noticed is that the html.set takes some time to execute and the dialog.resize() does not work because it is
called before the completion of the html.set call.
html.set also complicates the issue as it does not provide any handle (promise object) to let us know when it has finished execution.
so the below solution uses a setTimeout call to delay the execution of the dialog.resize(). Hence would advice to put the value of delay time depending upon some actual UI testing.
Modified code.
handle: function(error, ioargs){
var node = dom.byId(formID);
html.set(node, contentHTML, {parseContent: true});
var dialog = registry.bId("formDialog");
setTimeout( function(){
dialog.show();
dialog.resize();
},2000) // time delay of 2 seconds
}
