Subform Fields Are Read Only

[Former Community Member]

Hello, I'm not sure if this is a bug or a setting.  But I have a working form with subforms, if I copy a subform which already has controls on it and is functioning correctly and paste it (or duplicate it for that matter), when I preview it, those pasted controls are all read only and not able to type into them.

Anyone have any ideas why that would happen?

Thanks

Joe

*update*  I just uploaded the above image of the subforms, the top one correct, the bottom one after copy and pasting the top one and renaming it, it has now become read-only

Joe,

If you can you post a form extract with the two subforms, I can take look.

Here's a copy of the form with the two subforms.  Thanks for your help.

Joe,

I am not sure, but perhaps some script got removed when you cut-and-paste your extract because I did not see any script on the drop-down object or any data binding to the drop-down value. More importantly, I am not sure why the drop-down worked at all.

I removed the drop-down and added a button to call the InstanceManager to generate new instances of sub-form 'sfServer1'. The new sub-forms behave correctly.

Ah..I just caught this error and found your script on the sub-form calculate.

if (GenericNetworkInformation.ddlNumberofServers >= "1") then

sfServer1.presence = "visible" else

sfServer1.presence = "hidden"

endif

The attached form is updated.

Hey Steve,

That worked perfect.  I didnt' realize you could do add a second instance of subform using that command.

Is there anyway to get that to work via a drop down box instead of a button?  Thanks

Hi Joe,

No you cannot. The addInstance method does not take an integer argument. The method as commonly coded below can be misleading. The argument is a boolean 'true' and not an indication of the number of instances to add.

form1.Servers.Servers.sfServer1.instanceManager.addInstance(1);

Hey Steve,

Thanks a lot for the information.  It's nice to have a resource like you to help people like me.

Last question about this topic.  Is there a way then to count the amount of instances of a subform?

Thanks

You're welcome Joe. There are a lot of people who contribute to the forum to make it a useful resource.

I want to clarify my response about adding subforms using a drop-down. There is an instanceManager method called 'setInstances' that creates a specific number of subform instances. You could use a drop-down in the following manner.

// form1.Servers.GenericNetworkInformation.addServerDropDown::exit - (JavaScript, client)

form1.Servers.server.instanceManager.setInstances(this.rawValue);

Regarding getting the subform count, there is an instanceManger property called 'count'.

I added a drop-down and a button to get the count in the attached form.
