Hi all,

So I have 2 cards, card A and B. Card B has 3 android native field and some other labels and graphics. Whenever card A goes to card b, it always shows the 3 android native fields first before lagging and showing the rest. I have already tried using lock and unlock screen, putting the preopencard script into opencard. Wonder is it a bug or something I’m doing wrong. The reason why I’m using android native field is because I’m gonna use the keyboard type number so that the keyboard on screen only allows users to key in number.


Thanks!

Hi.

I do not develop for mobile, but is it possible that native fields are rendered apart from LC controls? In other words, can you hide, under LC script control, native fields? If you can, then something else is going on, because you ought to be able to control their "visible" property.

This is all conjecture.

Hi Craig,

So would I need to hide the native fields first and then show them when I enter the card?

Thanks!

as a failure behavior...could it be related ? Don't try to draw a Data Grid on a card that Is not open
When a Data Grid renders it dynamically creates fields and accesses certain properties. Some of these properties can not be properly reported by the Revolution engine unless the field is on an open card.

Hi,

I’m not really using a datagrid but more of a android native button/field.

Thanks!

I had a similar issue with odd redraws when changing cards. Try the latest rc version of LC and see if the problem persists. There were some fixes in that release that may help.

HI Jacque,

I have solved the issue, because there was some scripts in my preopencard handler which is getting data from my database which causes the app to lag a bit therefore, the android native field has shown first before the scripts are done. Does this counts as a bug?

Thanks !

I don't think it's a bug. PreOpenCard doesn't continue the handler until each command completes.

which is getting data from my database which causes the app to lag a bit therefore

so eddie, did you just add a small delay untill data was fully loaded to... "solve" that ?

Hi All,

I just moved the extracting data from the database script down to opencard handler and it solved my issue.

Thanks !
