So, your button is not close to the add button, so the reference to the instance manager will be different.Try using;xfa.resolveNode("form1.#subform.#subform.CARDS._Table1").setInstance(1);It can be easier if the subforms are named, so you don't have to use the class references like "#subform", whic...

Hi,Your file is password protected, so I haven't had a look.  But I would look at moving the code to populate the drop down item list into the preOpen event of the drop down, which is what it is for.  I would guess the enter event is being called more often than you expect.Also, from Reader 9.0 ther...

Hi,Sounds like you need a {DropDownList1}.clearItems(); somewhere in your code before you start adding the new items.If that doesn't help then add your code to the thread, or maybe a link to your form.RegardsBruce

That would make me think the "CARDS._Table1" part is wrong, if that returned null then an exception would be thrown and nothing else would happen.You should make sure you have the debugger setup in Acrobat under Edit ... Preferences ... JavaScriptIf you add a screen shot of your forms hierarchy pale...

Add the "this.resolveNode('CARDS._Table1').setInstance(1);" line before the "xfa.host.resetData();" line in your reset button click code.You can add the if statement from the add button, but it is only if some of your form users are still using Reader 8, which is pretty old now, it came out around 2...

Ok, so if the reset button is at the same level in your form structure, you will need;this.resolveNode('CARDS._Table1').setInstance(1);

Yeah, or probably the object name's instance manager.If you post the add button click code we can give you the exact syntax.

Hi,In you add button code there will be some code like {instanceManager}.addInstance(), where {instanceManager} is the name you gave the object in your form.In your reset button you want to use {instanceManager}.setInstance(1), which will set the number of rows to 1 (or whatever value you pass in).R...

Hi James,Ok, so the section in your form is just to group the two rows together?  I've only used sections to decide which rows to display or to do sub-heading/footers.In that case you want to remove the "this.parent.instanceManager.addInstance()" line from your add codeThe sequence number calculatio...

Hi James,Your add button seems to work with an extra .parent, sothis.parent.parent.instanceManager.addInstance();Or you could just have_Row1.addInstance()as the JavaScript engine will work up your form structure until it can resolve a nameBut the code in that add button click event also has the code...
