Got the installer working. Fixed a few bugs including a nasty-to-debug issue where the lang_id was being hardcoded during installation, resulting in strings being inserted with the wrong lang_id causing an infinfinite loop with fetch() throwing a "no strings" error and using template (which calls fetch()) to complain
tinyMCEPopup.requireLangPack();
function saveContent() {
if (document.forms[0].htmlSource.value == '') {
tinyMCEPopup.close();
return false;
}
tinyMCEPopup.execCommand('mcePasteText', false, {
html : document.forms[0].htmlSource.value,
linebreaks : document.forms[0].linebreaks.checked
});
tinyMCEPopup.close();
}
function onLoadInit() {
tinyMCEPopup.resizeToInnerSize();
// Remove Gecko spellchecking
if (tinymce.isGecko)
document.body.spellcheck = tinyMCEPopup.getParam("gecko_spellcheck");
resizeInputs();
}
var wHeight=0, wWidth=0, owHeight=0, owWidth=0;
function resizeInputs() {
if (!tinymce.isIE) {
wHeight = self.innerHeight-80;
wWidth = self.innerWidth-17;
} else {
