Hello everybody!
I'm working to two new B4XDialog template:
1. implementation of lazy loading in B4XListTemplate
2. merge of B4XSearchTemplate + B4XListTemplate + lazy loading - named: B4XSearchListLazyTemplate
The main issue is the 2nd template, the B4XSearchListLazyTemplate, and is present only in B4A but not in B4J (I've not B4i).
When I open it the first time, no problem; at second time I've a crash:
The error is given by the line “Dim p As B4XView = CustomListView1.GetPanel (s)".
I put a log to understand if there was a particular panel but any attempt the panel is different: sometimes no. 2, sometimes no. 7, this time no. 11 etc.
For the lazy loading I've used PreoptimizedCLV, which has the "only" issue to may not manage the customlistview colors and impacts the selection of customlistview items and the color of the letters when I use search (normally the letters in search are colored red), but compared to crashing it is a smaller problem. I've to work about it.
Anyone may help?
Thanks!
A little project is attached.
