[CLOSED] Problems with Hidden Field after SVN Update
Hello,
after an SVN Update (the first since ca. 6 months) we have some trouble with one of our old UserControls.
Here is the Code:
https://examples1.ext.net/#/GridPane...ous/Two_Grids/
but with a Tree at the left side.
The problem is, that the HiddenField is not really found. Firebug says:
ctl00_mainContentPlaceHolder_Fieldset7_Pluginaa35d 9125f5e4416a1d2917ba91b40b8_ItemGrid is not defined
Its a bit strange to me because it seems that the ClientId itself is resolved from:
#{ItemSelected}
to
ctl00_mainContentPlaceHolder_Fieldset7_Pluginaa35d 9125f5e4416a1d2917ba91b40b8_ItemGrid
But the object doesnt seem to be on the page.
Also a
Ext.get('ctl00_mainContentPlaceHolder_Fieldset7_Pl uginaa35d9125f5e4416a1d2917ba91b40b8_ItemGrid')
on the firebug console returns null. Ext.getCmp returns undefined.
Does anybody have an idea? Where there any specific changes the last months on Ext.NET or ExtJS?
As I said its a very old control. If I would build it new from scatch I would use normal JavaScript vars instead of Hidden fields
but we do not have time to rebuild several old UserControls after every Ext.NET udate ;)
So I hope that there is a another solution.
Regards,
Martin
