Error calling form from menu

Hello!
I recieve this error:

Exception calling form method 'treeNodeSelected' with arguments [52, nav_menu_items, 82, 198, null] on form 'svy_nav_fr_tree'in async mode on solution sampleuse_navigation

i am using: 3.0.1b3_6.1.rc2

how can i fix it?

Does the *_dtl or *_tbl form that it tries to load really exist? Is it extending svy_nav_base?

I vaguely remember getting this error in a case like that, but I’m not sure anymore what the exact cause was.

Yes it exists and i extend svy_nav_base but it doesn’t work

What does your layout look like? Which template and how many tabs?

This is my layout:
[attachment=0]Servoy_configurator_layout_product.PNG[/attachment]

It the same like the others two menu call

Looks good to me.
Can you also show a screenshot of the program you use?

The form is empty, it’s only linked to the db table

I don’t mean the form, but the program in the configurator.

Sorry… :confused:

[attachment=0]Servoy_configurator.PNG[/attachment]

This also looks good to me, not sure what causes the error yet.

Have you tried deleting and recreating this program and layout? Do you have the same problem then?

I found the error! But i don’t know how can i fix it :(

File: svy_nav_fr_main_base.js

var _tabForm = forms[_newFormName + "_p1_t1"].elements["form"].getTabFormNameAt(1);

This form works DOC

ElementScope {form:TABPANEL[name:form,x:0,y:34,width:901,height:657],toolbar:TABPANEL[name:toolbar,x:0,y:0,width:901,height:34]}

This form doesn’t work:

ElementScope {toolbar:TABPANEL[name:toolbar,x:0,y:0,width:901,height:34]}

i try to recreate the form a couple of time but nothig
