View Full Version : Combo Box's lazyRender config option appears to not working

15 Jun 2009, 5:36 AM
I use the "lazyRender" config option for a combobox to avoid it to be rendered before I ask it to do it. Unfortunately, it doesn't do anything: the field is rendered at the rendering of the form.

Here is my field configuration:

{name:'structures__codeconservation',fieldsetid:'structures_fieldset',fieldLabel:'codeconservation',hiddenName:'structures__codeconservation',xtype:'combo',emptyText:'Enter a value',triggerAction:'all',mode:'local',lazyRender:true,store:new mmw.bib_conservationStore,displayField:mmw.baseSfBib_conservationObject.displayField,valueField:mmw.baseSfBib_conservationObject.keyField},

Can someone help me to resolve this issue?

lazyRender is for when transforming a <select> It only transforms the <select> element when it (the ComboBox) is rendered.

Thank you for your answer. So, there is nothing in the config options to prevent the field from rendering?

Are you wanting it to be hidden?

No, in fact it's a bit complicated. I retrieve in one request the data of the stores of multiple fields. Then I use it to fill each store. The problem is that I must fill the store before the rendering of the fields (because I haven't succeeded to make visible the data contained in the field when I load the store data after the rendering of the field). So, I must stop the rendering of it until I retrieve the data (the data which will fill the store of the fields), and then I can fill the stores, and to finish, render each field.

Do your rendering after the Stores are loaded.

Yes I know, it's what I want to do, but the rendering is did automatically, and that's why I want to pause it (the rendering of the fields), to be able to do this manually. And that's the problem, I search a way to do this.

It's done when you ask for it to be done.

Ok I see, but now I can't render my fields because I must find them with the findField method of the BasicForm class (because I put the data of the fields in a array field identified by the name, or the hiddenName of the field), and it seems that this method doesn't work before the rendering of the field.
It's a real headache!

I dont get you.

WHy "must" you fnid them with findField?

Create them, and use them!

Sorry to resurrect such an old post, but this one is pretty similar to an issue I'm currently dealing with.

Putting the "why" question aside here for a moment, how does one make "it [rendering] done when you ask for it to be done."? Can you provide an example or documentation explaining how to do this?

Thanks and great work on ExtJS!
